The Southern Song in Suzhou: Revival and Prosperity

During the Jianyan period (1127–1130) of the early Southern Song (南宋), the Jin forces (金军) inflicted severe damage on Suzhou (苏州) during their northern retreat after occupying Hangzhou (杭州). The Jin regime was dominated by the Jurchen (女真人) people, whose ancestors were the Sushen (肃慎), inhabiting the Heilong River basin (黑龙江流域). At the end of the Northern Song (北宋), Aguda (完颜阿骨打) of the Wanyan clan unified the Jurchen tribes and rose against the Liao in 1114, proclaiming himself emperor of the Great Jin (大金) the following year. In 1125, after destroying the Liao, the Jin armies (金军) advanced south in two columns to attack the Song—eastern and western routes converging on Bianjing (汴京) (modern Kaifeng (开封)). In 1126, the Jin captured Bianjing and took the two Song emperors Huizong and Qinzong captive, ending the Northern Song. Zhao Gou, Qinzong’s brother, succeeded to the throne as Emperor Gaozong (宋高宗), with the reign title Jianyan.

In 1127, facing the Jin southward advance, Emperor Gaozong retreated south from Yangzhou’s (扬州) to Jingkou (modern Zhenjiang (镇江)), then via Changzhou and Wuxi (常州与无锡) to Suzhou. Though some wealthy families fled privately, market trade continued normally. The emperor lodged at the prefectural seat for three days before departing for Hangzhou, leaving Wang Yuan to defend Pingjiang (平江) (Suzhou). After reaching Hangzhou, Emperor Gaozong ordered Zhang Jun (張浚), Vice Minister of Rites—the civil-military coordinator soon charged with defenses on the southeastern front—to take supreme direction at Pingjiang (Suzhou). In March 1129, the generals Miao Fu and Liu Zhengyan launched a mutiny, killing Wang Yuan and forcing the emperor to abdicate. When the counterfeit edict reached Pingjiang, Marshal Zhang Jun (張俊), commanding field troops stationed along the prefecture’s approaches, refused to obey; he secretly conferred with Zhang Jun (張浚) (the two eminent contemporaries romanize homophonically though they are written with different Chinese characters) to organize loyalist counter-pressure. On March 20, Han Shizhong (韩世忠) army departed from Suzhou and defeated Miao’s forces at Linping. In April, Emperor Gaozong was restored to the throne, with Suzhou serving as the crucial base for suppressing the rebellion.

In July 1129, the Jin launched a large-scale invasion on multiple routes. On December 21, they captured Hangzhou. Emperor Gaozong retreated along the Zhedong Canal to Yuezhou (越州) (modern Shaoxing), Mingzhou (明州) (modern Ningbo), and finally to the sea off Wenzhou and Taizhou. After occupying Hangzhou, Wuzhu (兀术) decided to withdraw due to fierce Song resistance and the Jin troops’ inability to adapt to the southern heat. On February 16, Wuzhu led 100,000 soldiers northward along the Grand Canal (大运河). On February 18, the Jin attacked Xiuzhou (modern Jiaxing) and Chongde. The Song ordered Zhou Wang and Tang Dongye to defend Pingjiang. However, due to chaotic command and poor discipline, Guo Zhongwei and others retreated without fighting. On February 25, Jin troops entered through Panmen (盘门), looting government offices and residences. “Smoke and flames stretched over a hundred li, and the fire burned for five days.” In this catastrophe, sixty to seventy percent of Suzhou’s (苏州) population was killed—later counts recovered 62,000 male corpses and 25,000 female corpses on land, and 85,000 male and 111,000 female corpses from the rivers. The Jin also abducted 100,000 young men and women northward. It was truly “a city martyred whole”—the most devastating catastrophe in Suzhou’s history.

In 1161, Wanyan Liang led a massive army southward. The Song ordered Li Bao, deputy commander of Zhexi, to station at Pingjiang for defense. Prefect Hong Zun of Pingjiang criticized retreat strategies and supported Li Bao’s offensive approach. Li Bao later led his naval force straight to Jiaoxi (modern Shandong Peninsula (山东半岛)) and returned victorious. This success was inseparable from Hong Zun’s timely and ample supply of provisions, weapons, and boats. Pingjiang remained the logistical hub and material base for resisting the Jin, serving as the protective barrier for the temporary capital Hangzhou.

To restore order in Pingjiang Prefecture (平江府), the Song government took effective measures. First, Guo Zhongwei and others who had harmed the people during the anti-Jin war were severely punished to console the populace and stabilize morale, with military discipline strictly enforced. During the Jianyan period, when prefectural troops ran rampant, Tang Dongye immediately had two soldiers who broke into a widow’s shop and destroyed her wares “executed and displayed as a warning,” restoring social order. Second, taxes were reduced and the people comforted. In 1158, Emperor Gaozong ordered all overdue taxes in Pingjiang to be forgiven, with the imperial treasury supplying the shortfall. Third, urban construction was strengthened. During Wang Huan’s tenure as prefect (1144–1147), the prefectural office was rebuilt, the Gusu Gate (姑苏门) area was extensively developed, the Gusu Pavilion (姑苏台) was established inside the gate, the Gusu Terrace (姑苏台) was built atop the city wall, the Hundred Flowers Islet garden was created, and the Qiyun Tower was constructed. Seeing the city covered in rubble after the wars, Wang Huan ordered all boats entering the city to carry broken bricks and tiles out to the suburbs for rebuilding the city and official buildings. Through construction during the Shaoxing period, Suzhou gradually recovered its old form. During the Chunxi period, Prefect Xie Shiji used surplus funds of 400,000 strings to repair the city walls. In 1224, the court granted 30,000 coins and 20,000 shi of rice for wall repairs. In 1254, the moat was further expanded, making Suzhou’s walls “the finest in the circuit.”

Some Southern Song officials in Suzhou adhered to fairness and suppressed powerful local families. In 1136, Zhang Yi, as prefect of Pingjiang, specially appointed an assistant prefect to handle “equalizing taxes,” curbing the arrogance of wealthy magnates. In 1163, Zhang Xiaoxiang, serving as prefect, arrested powerful families who had seized property by force, confiscating tens of thousands of shi of grain from their estates. The following year, when central Wu suffered great famine, the people “survived by relying on this.” During the Jingding period, Bao Hui attacked powerful families occupying farmland, becoming renowned for “breaking up fortified estates, removing corrupt officials, handling major cases, and clearing debts.” Thanks to these political and economic stabilization measures, combined with cultural and educational flourishing, Suzhou recovered and developed. By 1184, Suzhou’s population had grown to 173,041 households with 298,405 adult males. By the late Southern Song, it had reached 329,600 households—over 1.6 million people by the five-person-per-household calculation—an unprecedented prosperity confirming its status as one of the nation’s great metropolises.

During the Jianyan period, the Song court retreated south of the Yangtze, elevating Hangzhou to Lin’an Prefecture as the temporary capital. The main defensive lines had three layers: the outer layer along the Huai River (淮河) and Han River (汉江) with the Qinling Mountains (秦岭); the second layer along the Yangtze River (长江); and the inner layer defending Lin’an’s periphery. As an auxiliary prefecture to Hangzhou with a quasi-capital status, Suzhou was, as ancients noted, “the most crucial zone for the capital region, more important than any other route.” It served as the corridor node connecting the Yangtze line to Hangzhou along the eastern shore of Lake Tai (太湖), the transition zone between the second defensive line and the capital. Xupu was an important naval base guarding against northern invasion by sea, heavily garrisoned. Suzhou remained a vital forward logistical base of immense military importance. Pingjiang (Suzhou) was the capital of the Zhexi Circuit (浙西路), hosting both the Judicial Intendant’s Office and the Tea-Salt Fiscal Intendant’s Office, administering fiscal and tea-salt affairs across eight prefectures and thirty-eight counties—making it the administrative and economic center of Zhexi.

During the transition between the Northern and Southern Song, large numbers of northern people migrated south with Emperor Gaozong, with many settling in Suzhou as new immigrants. The Southern Song population increased dramatically—rising by 12.76 million in just twenty years between 1159 and 1179, reaching nearly 30 million nationwide. The southern migrants came mainly from Jingdong (京东), Jingxi (京西), and Huaidong (淮东) circuits. In 1142, due to the large number of examination candidates, a special quota was added for sojourners. Among these newcomers were generals and officials from the north. Han Shizhong was the most outstanding representative. During the Jianyan period, he settled in Suzhou, taking the Canglang Pavilion (沧浪亭) as his residence, and was buried at Lingyan Mountain (灵岩山) after his death. The Han family thus became registered in Suzhou from the Southern Song onward—new Suzhou people. Another general’s descendant, Xu Suxing, believed that the Western Dongting Mountain (西洞庭山) “with its deep mountains and broad waters, beyond the reach of warfare, where one could farm and avoid disaster,” and so retreated there. Among the southern migrants were many intellectuals and their descendants. This massive north-to-south migration strengthened the south’s productive technical capacity, allowed superior natural conditions to be exploited, opened vast wastelands and abandoned lands, and enabled the southern economy to surpass the north. The arriving officials and intellectuals elevated the south’s cultural level, making the region “a gathering place of scholar-officials.”

The Song land system removed government limits on land ownership; as long as taxes were paid according to area, land accumulation was permitted. From late Northern Song into Southern Song, many powerful households concealed land without reporting it. In 1142, Li Chunnian, a Vice Director in the Secretariat’s Bureau of Personnel (Zuosi yuanwailang—the rank often translated as Left-Wing Outsider Gentleman Consultant), proposed the “Zhengjingjie”—a land survey to measure and verify holdings. He identified ten major harms from improper land boundaries, including cultivated land escaping taxation, inability to transfer ownership, exploitation of tenants, clerks manipulating tax categories, unreliable post-war tax records, concealed county revenues, powerful households falsely declaring holdings, and excessive taxes on abandoned land. Li began by surveying his own land meticulously, then had the people self-declare in groups of ten households. Actual land possession was used to compile household registers. Officials who completed this work without generating lawsuits were rewarded; those who delayed were demoted. During this process, Li wanted to raise Suzhou’s tax quota to the old 700,000 hu, but was opposed by Prefect Zhou Kui, who explained that the old figure was in unhusked grain, with two hu yielding only one hu of rice—so the old quota equaled the current 300,000 hu of rice. Thereafter, Suzhou’s tax was set at 300,000 hu. Overall, Li Chunnian’s “Zhengjingjie” verified actual landholdings, equalized tax burdens, and had positive significance, achieving “uniform land taxes, peaceful fields, and benefits for both public and private interests.”

The Southern Song local government in Suzhou showed concern for people’s welfare. Besides developing water conservancy, prohibiting lake reclamation, and providing relief, they adopted the “hedi” policy for fair grain purchases. In 1160, when Hong Zun served in the Ministry of Personnel, Suzhou suffered flooding. Farmers could not pay autumn taxes, and the tax office demanded payment in wheat the following spring. Hong argued that wheat prices were no lower than rice—why collect twice from people already suffering? He thus halved the tax and exempted disaster areas entirely. In 1164, Chen Han, as prefect, personally committed to flood control at Lake Tai, and the people built a temple on the Xu River in his honor. During the Qiandao period, Shen Du used 40,000 horses’ fodder (by imperial order) to relieve the people after floods, “saving many lives,” then mobilized production, soon achieving abundant harvests—earning him the title “good prefect.” In 1222, Zhao Yushu made “frugality and enriching the people” his priority. In 1268, Zhao Shunsun, as prefect and transport intendant, abolished the thirty-year practice of prepaying summer taxes by using his own salary and savings to purchase 200,000 shi of rice, winning popular acclaim: “the prefecture is well governed.” Some officials also protected commerce—Hong Zun repeatedly argued against government seizure of merchant ships, eventually returning them to ensure commercial transport continued.

Powerful ministers monopolized authority and accepted bribes openly. Some officials bought their positions and then plundered like bandits. Shi Miyuan’s son Shi Zhaizhi, once prefect of Pingjiang, as Vice Director of the Military Bureau in charge of fiscal planning, established land management offices in Zhexi, “putting greedy and shameless men in charge… stirring up the entire circuit.” The ruling class indulged in luxury, building gardens and pavilions while living in peaceful revelry. The late Southern Song prime minister Jia Sidao was extravagantly wasteful, indulging in wine, women, and song—nicknamed the “Cricket Chancellor.” He deliberately concealed military defeats, reporting victories when he had actually sued for peace, allowing the Yuan armies to advance eastward and hastening the Southern Song’s collapse.

The people’s burdens grew increasingly heavy. The Southern Song controlled only two-thirds of the Northern Song’s land, yet fiscal revenue exceeded it by 30%. Later Southern Song increased miscellaneous taxes like jingzhi qian, zongzhi qian, and yuezhuang qian. In the Liangzhe Circuit (两浙路) where Suzhou was located, these surcharges exceeded the main tax. By 1140, jingzongzhi qian revenue reached nearly 17.25 million strings, one-quarter of total Southern Song revenue. County officials extorted under various pretexts, sometimes five to eight times the legal amounts. Powerful families seized land and built estates; land concentration reached extremes. Self-cultivating farmers went bankrupt, becoming tenants of official or private estates. With such heavy burdens, especially in bad harvest years, people took desperate measures. In 1261, a great famine struck Liangzhe including Suzhou, with hungry civilians arming themselves to seize grain by force.

To adjust land structures, the Southern Song implemented “Zhengjingjie” and the “Gongtian” (public land) policy. The Gongtian Law had the government purchase excess land from official households to “suppress the strong and aid the weak.” Suzhou prefects Bao Hui, Cheng Gongce, and Wang Dalü were successively responsible. But in practice it became compulsory purchase. Initially exempting households under 200 mu, eventually “even 100-mu households were not spared.” Payment was mainly in paper currency, later even using empty honorary titles as collateral—intensifying ruling-class conflicts and harming middle farmers. As Zhou Mi observed: “Now seizing people’s land loses popular support, only aiding the Great Yuan’s (大元) advance.” The government also overissued huizi paper currency, which could no longer be exchanged for precious metals. When exchanging new for old, one new string equaled two old strings, inflicting invisible heavy losses. When the government tried to purchase grain with huizi, “the huizi was no longer accepted, new issues could not be exchanged, and the people closed their granaries and stopped trading.” Under such oppression, uprisings erupted across the south, and the Southern Song regime faced latent crisis.

Zhang Shijie (张世杰) (?–1279) was a renowned Southern Song general against the Yuan, rising from the ranks to become commander-in-chief. In February 1275, the Yuan defeated the Song at Wuhu; in March they captured Jian’kang (modern Nanjing (南京)). In April, Yuan chancellor Boyan (伯颜) sent Song defectors including Li Quan to recruit surrender. Li Quan brought troops to Suzhou’s Fengqiao (枫桥), where Prefect Qian Shuoyou fled, and officials including Tongpan Hu Yu opened the gates. At this time, Zhang Shijie came via Raozhou (饶州) to the temporary capital (Hangzhou), bearing the titles of Baokang Army Commissioner and Chief of the Metropolitan Command. Zhang dispatched generals in all directions, defeating Li Quan and others, “recovering Pingjiang, Guangde (广德), and other prefectures.” In July, he joined Liu Shiyong for the battle at Jiaoshan, but was defeated by Yuan general Aju’s fire attack and retreated to Chuanshan. Soon promoted to Dragon-Spirit Guard Commander, he became Riverine Pacification Commissioner in October. With Yuan forces approaching Hangzhou at Dusong Pass, the court summoned Wen Tianxiang (文天祥) from Suzhou to defend the capital. Wen’s position as “Prefect of Pingjiang” was temporarily assumed by Zhang Shijie as Baokang Army Military Commissioner. Zhang established his headquarters in Suzhou but soon left to defend Hangzhou. In January 1276, Zhang proposed combining forces with Wen Tianxiang for a decisive battle, but was blocked by Chancellor Chen Yizhong. He subsequently supported Zhao Shi and Zhao Bing, retreating to Fuzhou and then Xinhui (modern Guangdong) Yashan, finally dying at sea. Zhang Shijie left a significant mark in Suzhou’s history of national resistance.

Wen Tianxiang (1236–1283), styled Songrui and Lushan, from Ji’an, Jiangxi (江西), passed the jinshi examination in 1256 at age twenty. In 1275, with the Yangtze front critical, the court summoned all to defend the dynasty. Wen raised troops in Ganzhou and marched with 10,000 to the capital. He was appointed Right Chancellor and Military Affairs Commissioner, commanding all route forces as Pacification Commissioner of Jiangdong (江东) and Jiangxi, and Prefect of Pingjiang—responsible for Jiangnan (江南) military affairs. In October, as Boyan’s Yuan forces advanced east toward Changzhou (常州), Wen dispatched generals Yin Yu, Ma Shilong, and Zhu Hua with 3,000 Gan troops to aid. On October 26, Ma Shilong laid ambush at Wumu Guangqiao on the Changzhou-Wuxi border (常州与无锡交界). When Yuan forces attacked, Ma’s ambush sprang, killing many, but Yuan numerical superiority grew and Ma died fighting. Zhang Quan watched from the opposite shore, doing nothing. On the 27th, Yuan forces attacked Wumu in full strength. Zhu Hua’s troops fought fiercely from morning to noon. In the afternoon, Yin Yu’s men pressed forward, killing two Yuan soldiers, but Zhang Quan still refused to help. Defeated, Zhu Hua’s troops retreated across the water, and Yuan forces turned on Yin Yu. Yin led 500 warriors personally, was captured after exhausting his strength, and died under torture. Of his 500 men, only four returned to Suzhou. In this battle, Yang Zongda and his son Jiliang from the Suzhou-Wuxi (无锡) border also led thousands of local militia to fight and sacrifice at Changzhou. Song supplies for this campaign came from Suzhou; Pingjiang was an important anti-Yuan base for Wen Tianxiang.

Meanwhile, another Yuan force captured Anji, threatening Dusong Pass—Hangzhou’s outer defense. Chancellors Liu Mengyan and Chen Yizhong reassigned Wen Tianxiang’s army to defend Hangzhou. Wen delegated Tongpan Wang Juzhi and commander Wang Bangjie to hold Suzhou. Early December, shortly after Wen left Pingjiang, Boyan’s forces took Wuxi and advanced on Wangting. Wang Juzhi and Wang Bangjie went to Hanshan Temple to surrender. In January 1276, the Song court sent Wen as Right Chancellor and Military Affairs Commissioner to negotiate with Boyan at Suzhou; he was detained and escorted north. He escaped at Zhenjiang and, with popular support, fled to Tongzhou (modern Nantong), crossed to Fujian, and joined Lu Xiufu and Zhang Shijie in resistance. In 1277, he operated in Jiangxi, where anti-Yuan volunteers gathered, recovering many counties. Later captured at Wupoling and sent to Dadu (大都) (modern Beijing), he endured repeated threats and temptations but never yielded. He was executed at Chaishi in February 1282, at forty-seven. A note found in his clothing read: “Having read the sages’ books, what did I learn? From this day forth, I shall be without shame.” Suzhou was his important starting point for anti-Yuan resistance; later generations built the Prime Minister Wen Shrine at the site of his former prison to commemorate him.

The Southern Song attached great importance to Jiangnan water conservancy, with drainage of Lake Tai waters remaining the priority. In 1158, the court augmented river-dredging troops and strengthened water management and maintenance. Responding to Vice Transport Intendant Zhao Ziqian’s request, various rivers were dredged. In 1159, the court ordered Censor Ren Gu to open waterways in Pingjiang (Suzhou), starting from an eastern dredging reach abbreviated as “Dong—” in the archival digest (likely an eastern channel head in Changshu (常熟)) and opening Fushan Tang. In 1164, Prefect Shen Du opened ten harbors in Kunshan (昆山) and Changshu to connect the Yangtze, costing over 300,000 strings and 90,000 shi of rice. In 1165, dredging troop numbers were replenished, and harbors in Kunshan and Changshu were opened to the sea. In 1175, Xupu Harbor (浒墅关) was dredged, with embankments built. Intendant Xue Yuanyi memorialized to open fifty li of canal. In March 1178, Transport Commissioner Wei Jun re-dredged Zhihe Tang, completed in two months with wealthy residents contributing labor. In 1186, Zhexi Intendant Luo Dian memorialized to open Dianshan Lake (淀山湖). In 1190, Intendant Liu Ying dredged Dianshan Lake to drain Wusong River (吴淞江) waters, prohibiting encroachment. During Emperor Lizong’s reign, thousands of naval troops were stationed at Weijiang, Jiangwan, and Fushan to maintain rivers and lakes. In 1232, Wujiang Long Bridge (吴江长桥) was repaired. Southern Song water management was handled by specialized agencies with military support, forming a comprehensive irrigation and drainage system that created conditions for high agricultural yields.

Due to frequent Song-Jin warfare and population flight, much wasteland appeared. The Southern Song encouraged reclamation. In 1132, Emperor Gaozong issued an edict allowing people to claim abandoned land after two years, with original owners allowed to reclaim within ten years. This encouraged displaced households to return and open wasteland. At that time, 36,000+ qing of abandoned land in Suzhou awaited original owners’ claims within two years. The Southern Song continued the Wudai practice of poldering: “building earth embankments according to terrain, enclosing hundreds or thousands of qing as arable land.” These polders could reach over 1,000 qing. Yang Wanli noted: “There are also polder fields, with layered embankments keeping out external water—similar to this, even fields with occasional water level differences are protected from harm.” Suzhou’s sand fields also developed. Sand fields were “people managing riverside and lakeside accretion land as farmland”—near water, consistently moist, suitable for rice and mulberry, often yielding abundant harvests. In 1159, due to inaccurate surveys, increased rents on sand fields were abolished. In 1166, the court again debated sand field taxes. In 1170, Ye Boyan surveyed 8.2 million mu of sand fields in Zhexi, Huaidong, and Jiangnan circuits—showing considerable scale. Suzhou also continued developing floating fields (fengtian), which floated on water and were naturally flood-proof—especially suitable for water-rich Suzhou.

Through rewarding agriculture, expanding cultivated area, improving soil quality, using new implements and superior seeds, and strengthening field management, agricultural output increased dramatically. “When Suzhou and Huzhou harvest, the world is fed” became accepted wisdom.

In the Southern Song, improved iron-smelting technology made steel-edged wrought-iron tools more common, with farming implements becoming tougher and sharper. Traditional tools like the Jiangdong plow were more finely crafted. The government promoted the huadao (cutting plow) and the tali (tread plow). The huadao was like a short sickle with a thick back, specifically for clearing reeds and weeds, “saving more than half the labor.” The tali, also called changji, was a human-powered plow: “pressing down on the rear of the plow handle with the foot so the blade enters the soil, then pulling back on the handle”—solving the shortage of draft animals when cattle were scarce. Suzhou, the land of water and lakes, grew rice everywhere, using various water-lifting devices: water-powered chain pumps, treadle chain pumps (dragon-bone water wheels), water-driven wheels, high water wheels, tube wheels, bailers, and shadoofs. These diverse irrigation tools brought convenience to Suzhou’s water country.

Seed cultivation and selection were crucial to agriculture. Suzhou had a tradition of developing superior varieties. Kunshan and Changshu had dozens of rice varieties—Kunshan alone had 34: 14 early rice (xian), 11 mid-season, and 9 glutinous. Changshu had nearly 40: 21 early, 8 late, and 8 glutinous. Champa rice was further improved; Jiangnan farmers adapted it into “dry champa” suitable for water-scarce upland fields, which Suzhou promoted in hilly areas. Wheat became widespread in the Southern Song: “Wheat planted field after field, willows lining every bank,” with varieties including short wheat, late wheat, and Huai wheat. With many northerners migrating to Liangzhe, demand for wheat flour drove prices up, and “farmers profited, doubling rice cultivation returns,” leading to “competitive spring wheat planting.”

Field management was strengthened. Suzhou primarily grew japonica rice—large grains with excellent flavor. On thinner upland soils, indica was planted more—smaller grains of inferior taste but shorter growing seasons and higher yields. The rice-wheat double-cropping system was implemented: “When plum blossoms bloom I plant wheat, when peach and pear petals fly the wheat stands tall… Harvesting wheat with sickles in clear weather, for tomorrow’s rain would muddy the grain. Paddies await rain for late rice transplanting, out at dawn to move seedlings, eating wheat at night.” This vividly shows the sequence of harvesting wheat then planting late rice. Intertillage and weeding were strengthened, with field weeding to remove harmful weeds. Wheat required ridge-making, the earth formed into ridges for better growth. With northern migration, wheat cultivation and management advanced, improving both yield and quality. Pest control was also intensified; during Emperor Xiaozong’s (宋孝宗) reign, the government issued rewards for locust capture.

Favorable natural conditions, improved implements, advanced techniques, and superior seeds made Suzhou a nationally renowned grain production base. Since the mid-Northern Song, it had become “the state’s granary.” After the Song court moved south, the Suzhou region became “the famous prefecture near the capital, the main source of supply, extending to other circuits.” Southern Song Suzhou’s (南宋苏州) Changping, Guiren, and Baogong granaries were abundantly stocked. In December 1186, “Intendant Luo Dian stated: The Changping and Guiren granaries of Pingjiang store half the grain of the entire circuit; the warehouse buildings are leaning, requesting 10,000 strings from prefectural funds to build thirty rooms for grain storage. Approved.” This shows Pingjiang’s grain abundance. Hangzhou consumed 1,000–2,000 shi of rice daily, with Suzhou as the primary supplier. As for yields, superior fields produced 5–6 shi of unhusked rice per mu, or 3–4 shi of husked rice. Due to these high yields, the Southern Song government requisitioned up to 1.5 million shi of grain under “hedi” purchases—exceeding other regions.

A major event in Southern Song Suzhou agricultural history was the introduction of cotton from elsewhere. Cotton, also called mumian, spread to Suzhou during the Southern Song; “the methods of cultivation and processing gradually came north, with Jianghuai (江淮) and Chuan-Shu already profiting.” Due to cotton’s economic benefits, the Southern Song government began taxing it as summer tax. Suzhou cotton was mainly produced in Taicang (太仓), Jiading, and Changshu along the riverfront highlands. Suzhou also had numerous fruit varieties, including citrus from the Eastern and Western Dongting Mountain (洞庭山) s, “with surpassing fragrance and flavor.” Green tangerines were especially large, edible before frost when still deep green. Square-stem persimmons, named for their square stems, were “red as rouge, uniquely sweet and soft, unmatched by other red persimmons.” Han pears from Changshu’s Han Mound did not discolor after cutting, making them uniquely expensive and “the finest in the world.” Xiangshan chestnuts from Changshu’s Xiang Mountain “surpassed ordinary chestnuts in fragrance, also called deer fragrance pouches.” Watermelons came from the Western Regions; “in recent years watermelons are eaten everywhere,” and Suzhou was also a production area.

In the Southern Song, silk reeling became widespread in rural household handicraft. When barley turned yellow and fragrant cocoons matured, “aunts and daughters call each other to the bath, boiling cocoons behind the house with fragrance at the door, reeling wheels noisy as wind and rain, thick grass and long silk without breaks… Tomorrow selling silk at the West Gate”—this reflects rural silk production. Suzhou silk textiles focused on fineness, density, and lightness. Wu ling (Wu satin) had long been renowned alongside Chu silk, Shu brocade, and Qi silk. Suzhou brocade was listed as an important tribute item. With the Southern Song capital at Hangzhou and Suzhou nearby, it was a key brocade supply center. Song brocade was elegant and classical, richly toned, used for clothing, temple decoration, and scroll mounting. Kesi (Chinese cut-silk tapestry), also spelled kesilk in older references, used raw silk as warp and colored or plain boiled silk as weft to weave patterns. The technique could then “produce any desired floral or animal design.” Masters such as Shen Zifan and Wu Ziyou were famous in their time. Southern Song silk products went north via Huai’an, Sizhou, and other border markets to Kaifeng and Yongxingjun (modern Xi’an), then west through the Hexi Corridor (河西走廊). By sea, they reached overseas via Quanzhou and Ningbo. During lantern festivals, Suzhou used silk for lanterns with delicate textures and varied forms, especially dazzling on the Lantern Festival night, making people “dazzled and intoxicated.” Kunshan’s hemp fabric yaobanbu and Xuguan (Dongqiao) floral mats also developed. Notably, cotton textile manufacturing emerged as a significant industry; by the mid-to-late Southern Song, household-based cotton spinning and weaving had developed substantially, especially in Suzhou’s riverside areas where villagers made it an important sideline.

During the Qingyuan period (1195–1201), Suzhou’s papermaking improved noticeably, with abundant raw materials and developed techniques producing various colors and patterns. The government’s open policy toward printing made both state and private publishing active. Schools and temples were especially important printing bases. Temples mainly printed Buddhist sutras. In 1216, Qisha Yansheng Temple in Pingjiang (Suzhou) established a sutra workshop, hiring craftsmen to carve and print Buddhist texts—a project that continued until 1322 in the Yuan dynasty. The complete canon comprised 6,312 volumes, arranged by the Thousand Character Classic. The Qisha Canon expanded on previous sutra collections and was finely produced. Surviving Southern Song prints include the forty-volume Beiji Zongxiao Fang (1154) published by Pingjiang Prefecture, the seven-volume Fanyi Mingyi Ji (1157) from Jingde Temple, the Liu Xiansheng Ji (1166), and Li Jie’s Yingzao Fashi (1228–1233).

Tea was essential to daily life. Suzhou had an excellent tradition of tea cultivation and processing. Shuiyue tea’s roasting techniques continued during the Southern Song. Legend has it that “flower tea” production began in Southern Song Suzhou. There was also “Fufang” tea: “round, thick leaves, picked in summer, roasted over fire for fragrance, brewed as a drink of emerald color and aroma.” “Baiyun tea” from Shanqiu was also famous. Suzhou’s culinary heritage featured aquatic products and fish with distinctive Wu-region flavors. Common processed foods included sugar dumplings, popcorn (baolilou, made by popping glutinous rice in pots), cangtuan (rice flour cakes), jingsu cakes, liaohua, mi cakes, and guozheng (glutinous rice wrapped in zong leaves and steamed). Fish products included traditional perch, whitefish, yellow croaker, and pufferfish. Pufferfish was highly poisonous, “yet people greatly prized it.” Skilled chefs could remove the toxins, making it deliciously edible. “When Wu people entertained guests in early spring, having this fish made it a grand feast. Cooked in the morning and served when guests arrived, without reheating—it was said to be especially delicious.”

Suzhou had long been a shipbuilding center. The Southern Song’s Liangzhe Circuit (including Suzhou) built sharp-bottomed iron-headed boats for transporting military supplies to the temporary capital (Hangzhou). Various prefectures in Liangzhe also built nine-wheel and thirteen-wheel paddle-wheel warships. The “wheels” were treadle-powered paddle wheels replacing oars and sculls. The Pingjiang shipyard also built eight-scull warships and four-scull seagoing vessels. The “eight-scull” was eight zhang long, costing 1,159 strings; the “four-scull” was 4.5 zhang, costing 329 strings. In 1135, the Liangzhe shipyard copied and improved the Yang Me paddle-wheel boats, building three-story nine-wheel vessels carrying over 1,000 people for government and military use. Thanks to great shipbuilding advances, vessels from Suzhou and Jian’kang played huge roles in anti-Jin naval warfare: “The warship designs of recent times are so exquisite that human ingenuity seems insufficient. The barbarians gaze upon them, startled as if by ghosts and gods. With waters stretching to the horizon and waves like mountains, though they be tigers, leopards, and wolves, none dare advance.” In 1978, a damaged Southern Song wooden ship was excavated at Fengxiang Township, Jiading County (嘉定县). Restored, it measured about 10 meters long, 1.85 meters wide, and 0.95 meters deep, with seven compartments and approximately five-ton capacity—a transport vessel.

Metal casting developed significantly in the Southern Song. After the court moved south, the Imperial Armory was established, producing tens of thousands of weapons annually. During Emperor Xiaozong’s reign, armory craftsmen increased to over 3,000, with Suzhou hosting weapons workshops. Suzhou also produced high-value bronze wares and gold and silver objects. Clay sculpture was also popular in Suzhou, using front-shop, back-workshop integrated production-sales models, even developing chain operations with branches in various locations. The Zhenjiang archaeological team excavated a Song dynasty clay sculpture shop at Luotuo Ridge, finding numerous clay child figures, tools, and pigments, with inscriptions like “Wujun Bao Renzu” and “Pingjiang Sun Rong” on the backs. This was likely a branch opened by Suzhou craftsmen in Zhenjiang. Suzhou’s clay figure craft continued into the Ming and Qing; the child figures were called “clay beauties,” with on-the-spot portraits for travelers called “pinching portraits.” Zhu Mu noted that Suzhou “craftsmen excel at clay sculpture, and their Mahoraga figures are especially exquisite.”

Ceramic, tile, and brick manufacturing continued developing in Southern Song Suzhou. The suburbs had many kilns, with “kiln smoke” treated as scenery, indicating flourishing household-based pottery and brickmaking. As Fan Chengda’s poem noted: “Outside the gate, kiln smoke forms a scene.” Suzhou also produced tall furniture and other wooden goods.

In the Southern Song, the commodity economy continued developing, with agricultural and handicraft products increasingly entering markets. Tea, rice, silk, cotton, fruit, aquatic products, and vegetables all became commodities. Around Lake Tai, specialized tea farmers, fruit growers, sugarcane planters, and vegetable farmers appeared in large numbers, alongside artisans, forming a vast small-commodity production and trading force. Some grain crops became important commodities. Records state that in 1174, a wealthy Changshu farmer named Zhang Sanba negotiated to sell 80,000 jin of rice to a merchant. Specialized cash-crop areas had to purchase food grain externally. In the winter of 1132, the Eastern and Western Mountains “suddenly turned very cold, Lake Tai froze, rice boats couldn’t arrive, and many mountain dwellers starved”—showing deep agricultural commodification and dependence on markets. Suzhou’s famous vegetables included song (modern Chinese cabbage), “with broad leaves, hence called broad-leaf Wu song.” Chuanxiong was also an important ingredient for fish soup.

Aquatic products also became important commodities. Yijian Zhi records a Kunshan boat loaded with soft-shelled turtles worth 30,000 coins, destined for Hangzhou. It also notes two commoners in central Wu “both selling eels as a trade,” earning 300 coins daily. A Kunshan man named Shen Shijiu “could repair and mount paintings and calligraphy for others, while his family supported itself by cooking crabs.” Selling crabs became a livelihood. This shows turtles, eels, and crabs had all become commodities, with huge aquatic product consumption. Suzhou was truly the land of fish and rice. Cities and rural towns formed fish markets, trading traditional perch, whitefish, yellow croaker, and pufferfish.

Taverns and various service businesses were everywhere; even mountain villages and waterside hamlets had wine shops. “Woodcutters’ poles fill the autumn clouds on the hillside”—wine banners in the trees were especially eye-catching. Taverns were often located by water at key transit points. At Wujiang’s (吴江) Pingwang, “all along the river are wine-selling houses, with many customers at each.” Famous taverns did especially brisk business. Taverns “all hung large curtains outside, made of several pieces of blue-white cloth, sized according to the establishment’s scale; village shops might hang just a single wine bottle.” The development of Suzhou’s service industry reflected the vitality of the commodity economy and the richness of people’s lives.

As the urban commodity economy developed and material consumption rose, demand for spiritual enjoyment grew, stimulating flower and plant cultivation. Some households specialized in growing flowers for market supply. Suzhou native Fan Chengda recorded in his Chrysanthemum Treatise dozens of cultivated varieties—thirty-six types alone transplanted to Fancun in 1186. Chrysanthemums were especially beloved in Suzhou. Flower-selling households east and west of the city “planted them as far as the eye could see, and every family grew their own.” Suzhou chrysanthemum cultivation was exquisite: “The more they were pinched, the more branches grew, with thousands of blooms forming on the main stem by autumn.” Suzhou also imported varieties from elsewhere—Fan Chengda brought “city plums” from Sichuan to Wu. Peonies came from Luoyang (洛阳) to Suzhou and became extremely popular. Zhu Mian had a garden inside Changmen (阊门) with over 10,000 peonies. Scholar-official families widely cultivated them: Judicial Intendant Lan Shucheng had 3,000 plants of varieties like Bai Wanyu and Jingyunhong; Prefect Lin Dezhi had 1,000. Jin Linjian, grafted in Nanjing and passed through Hangzhou’s imperial gardens to Suzhou, produced “such magnificent and beautiful flowers that a hundred other varieties paled in comparison.” The abundance of Southern Song Suzhou’s flower and tree varieties promoted the flower market’s prosperity.

In the Southern Song, Suzhou’s small towns continued rising. Lilizhen in Wujiang County (吴江县) gradually developed when jinshi Li Zhi and his brothers settled there during the Yuanyou period; it became notable during the Chunxi period when Vice Minister of Works Zhao Panlao resided there. Lu You, passing through Helucun below Lili on his way to Shu, noted “dense inhabitants, especially numerous wine sellers.” Jinxizhen in southwestern Kunshan was anciently called Jinxi; in 1163 it became known due to the water burial of Consort Chen. Fushanzhen in northern Changshu was established in the early Jianyan period with naval garrisons, flourishing due to military consumption and services. Xupu similarly prospered from military-civilian settlement and trade. Tongli (also called Tongchuan) in Wujiang was established as a town in the Song; originally called Fushi (“wealthy scholar”), it was considered too ostentatious and renamed by splitting the characters. Zhenze Town in Wujiang was established during the Shaoxing period, located southeast of Lake Tai with convenient water and land transport and abundant products. Tuncun became a bustling town when scholar-commoners settled there after migrating south with the Song regime. Guangfuzhen in Wuxian had “over a thousand households and crisscrossing paths” in the Southern Song, densely populated as an agricultural product distribution center. Tangli and Houbao on the Western Mountain also became towns from clan settlement. Suzhou, called paradise since the Song, became especially renowned in the Southern Song. According to Fan Chengda’s Wujun Zhi on wards and markets, Suzhou’s commercial establishments included rice markets, brocade workshops, silk markets, fish markets, fruit markets, and entertainment venues like Wuwufang.

The Southern Song continued the Northern Song currency system, circulating copper coins and silver. To prevent copper from flowing to the Jin, iron coins were issued in the Jianghuai region. Besides jiaozi, paper currencies included qianyin, xiaochao, gongju, and guanzi. The most widely issued paper currency was huizi. “Bianqian huizi” had long replaced metal currency among the people. In 1160, Qian Duanli, Vice Minister of Revenue, following government orders, created huizi for circulation in and outside the city. Huizi thus transitioned from private to official issue, with denominations of 1, 2, and 3 strings, later adding 200, 300, and 500 wen notes. The Southern Song government overissued huizi, which could no longer be exchanged for precious metals. When exchanging new for old, one new string equaled two old strings, inflicting invisible heavy losses. With excessive issuance, “the numbers increased daily while the value decreased daily,” causing severe price inflation and disrupting production and life. Suzhou also had records of long-distance merchants—during Emperor Lizong’s reign, a young man named Zhu Fu ventured south toward the Guangdong–Guangxi trading belt for commerce but died there; his wife Qian traveled to recover his body, enduring great hardships. Such far-reaching Suzhou merchant journeys demonstrate the city’s powerful commercial radiation.

Suzhou’s foreign trade was always notably developed. The Song established a Maritime Trade Office at Qinglong Town (northeast of modern Qingpu, Shanghai) specifically for overseas trade, with foreign goods transported to Suzhou. Suzhou-area “seagoing vessel” households profited several-fold through maritime commerce. With abundant grain and exquisite handicrafts, Suzhou exported heavily to the north, mainly via the Grand Canal to Sizhou or Xuyi, promoting north-south economic exchange. The comprehensive development of Southern Song Suzhou had multiple causes: superior Jiangnan natural conditions with ample rain, fertile soil, and convenient transport. During the Jingkang-Jianyan disasters, masses migrated south—“Central Plains (中原) scholars and people, supporting each other southward, numbering tens of millions.” Among the migrants were many highly educated people; scholar-officials and students mostly brought their families south, settling in Pingjiang and other southern areas, making the region “a gathering place of scholar-officials.” They brought advanced culture, comprehensively elevating population quality, including farming and craft skills, providing opportunities for Southern Song Suzhou’s economic and cultural development.

The Southern Song period (南宋时期) (1127–1279) witnessed Suzhou’s dramatic journey from destruction to rebirth. The Jin invasion during the Jianyan period inflicted unprecedented catastrophe—“a city martyred whole”—with over 100,000 people slaughtered. Yet relying on superior geographical location, natural conditions, and population advantages, under Southern Song governance and people’s tireless labor, Suzhou rapidly recovered. Politically, as capital of the Zhexi Circuit and auxiliary prefecture to Hangzhou with quasi-capital status, it served as a protective barrier for the temporary capital and a logistical base for anti-Jin resistance. Economically, the proverb “When Suzhou and Huzhou harvest, the world is fed” fully materialized; Suzhou became the nation’s most important grain production base, its ever-normal granaries holding half the circuit’s reserves. In handicrafts, Song brocade, kesi tapestry, cotton textiles, shipbuilding, papermaking and printing, and clay sculpture all developed comprehensively. In commerce, the commodity economy expanded, services flourished, flower markets prospered, small towns rose, huizi currency circulated widely, and foreign trade thrived. Demographically, from initial devastation to 329,600 households by the late Southern Song—about 1.6 million people—it reached unprecedented prosperity. However, late Southern Song ruling-class corruption, with power-hungry ministers like Jia Sidao harming the state, land concentration, and crushing taxes burdened the people, ultimately leading to Suzhou’s fall to the Yuan in 1276. The anti-Yuan struggles of national heroes Wen Tianxiang and Zhang Shijie in Suzhou left a glorious chapter in the city’s history.
