Sichuan, previously romanized as Szechwan or Szechuan, is a province in Southwestern China, occupying the Sichuan Basin and Tibetan Plateau—between the Jinsha River to the west, the Daba Mountains to the north, and the Yunnan–Guizhou Plateau to the south. Its capital city is Chengdu, and its population stands at 83 million. Sichuan neighbors Qinghai and Gansu to the north, Shaanxi and Chongqing to the east, Guizhou and Yunnan to the south, and Tibet to the west.
During antiquity, Sichuan was home to the kingdoms of Ba and Shu until their incorporation by the Qin. During the Three Kingdoms era (220–280), Liu Bei's state of Shu Han was based in Sichuan. The area was devastated in the 17th century by Zhang Xianzhong's rebellion and the area's subsequent Qing dynasty conquest. However, the area recovered to become one of China's most productive areas by the 19th century. During World War II, Chongqing served as the temporary capital of the Republic of China, and was heavily bombed. It was one of the last Mainland China areas captured by the People's Liberation Army during the Chinese Civil War, and was divided into four parts from 1949 to 1952, with Chongqing restored two years later. It suffered gravely during the Great Chinese Famine (1959–1961) but remained China's most-populous province until Chongqing was again separated from it in 1997.
The Sichuanese people speak distinctive dialects of Mandarin Chinese. The Sichuan pepper, with its distinctive flavor and numbing effect, is prominent in modern Sichuan cuisine, featuring dishes, including Kung Pao chicken and mapo tofu, that have become staples of Chinese cuisine around the world. There are many Giant panda stations in the province and large reserves for these creatures, such as the Chengdu Research Base of Giant Panda Breeding.
Sichuan is the 6th-largest provincial economy of China, the largest in Western China, and the second-largest among inland provinces after Henan. As of 2021, its nominal GDP was (US$847.68 billion), ahead of that of Turkey ($815 billion). If it were its own country, Sichuan would be the 18th-largest economy and 19th-most populous as of 2021.
In antiquity, the area of modern Sichuan including the now-separated Chongqing Municipality was known to the Chinese as Ba–Shu, in reference to the ancient state of Ba and the ancient kingdom of Shu that once occupied the Sichuan Basin. Shu continued to be used to refer to the region to the present day; several states formed in the area used the same name, for example, the Shu Han of the Three Kingdoms period (220–280), and Former Shu and Later Shu of the Ten Kingdoms period (907–979). Currently, both characters for Shu and Chuan are common abbreviations for Sichuan.
The region was formerly referred to as "West China" or "Western China" by Protestant missions.
Ba stretched into Sichuan from the Han Valley in Shaanxi and Hubei down the Jialing River as far as its confluence with the Yangtze at Chongqing.
Shu occupied the valley of the Min, including Chengdu and other areas of western Sichuan. The existence of the early state of Shu was poorly recorded in the main historical records of China. It was, however, referred to in the Book of Documents as an ally of the Zhou. Shujing Original text: 王曰:「嗟!我友邦塚君御事,司徒、司鄧、司空,亞旅、師氏,千夫長、百夫長,及庸,蜀、羌、髳、微、盧、彭、濮人。稱爾戈,比爾干,立爾矛,予其誓。」 Accounts of Shu exist mainly as a mixture of mythological stories and historical legends recorded in local annals such as the Chronicles of Huayang compiled in the Jin dynasty (266–420), and the Han-dynasty compilation . These contained folk stories such as that of who taught the people agriculture and transformed himself into a cuckoo after his death. The existence of a highly developed civilization with an independent bronze industry in Sichuan was excavated in 1986 at a small village named Sanxingdui in Guanghan, Sichuan. This site, believed to be an ancient city of Shu, was initially discovered by a local farmer in 1929 who found jade and stone artifacts. Excavations by archeologists yielded few significant finds until 1986 when two major sacrificial pits were found with spectacular bronze items as well as artifacts in jade, gold, earthenware, and stone. This and other discoveries in Sichuan contest the conventional historiography that the local culture and technology of Sichuan were undeveloped in comparison to the technologically and culturally "advanced" Yellow River valley of north-central China.
Qin armies finished their conquest of the kingdoms of Shu and Ba by 316 BC. Any written records and civil achievements of earlier kingdoms were destroyed. Qin administrators introduced improved agricultural technology. Li Bing, engineered the Dujiangyan irrigation system to control the Min River, a major tributary of the Yangtze. This innovative hydraulic system was composed of movable weirs which could be adjusted for high or low water flow according to the season, to either provide irrigation or prevent floods. The increased agricultural output and taxes made the area a source of provisions and men for Qin's unification of China.
In 263, the Cao Wei of North China conquered the Kingdom of Shu-Han as a step on the path to reuniting China. Salt production becomes a major business in Ziliujing District. During the Six Dynasties period of Chinese disunity, Sichuan began to be populated by non-Han Chinese ethnic minority peoples, owing to the migration of Gelao people from the Yunnan–Guizhou Plateau to the Sichuan basin.
It was also during the Song dynasty that the bulk of the native Ba people of eastern Sichuan assimilated into the Han Chinese ethnicity.
In the 12th and 13th centuries, the Southern Song dynasty established coordinated defenses against the Mongols Yuan dynasty, in Sichuan and Xiangyang. The Southern Song state monopolized the Sichuan tea industry to pay for warhorses, but this state intervention eventually brought devastation to the local economy. The line of defense was finally broken through after the first use of in history during the six-year Battle of Xiangyang, which ended in 1273. Allegedly there were a million pieces of unspecified types of skeleton bones belonging to war animals and both Song and Yuan soldiers who perished in the fighting over the city, although the figure may have been grossly exaggerated. The recorded number of families in Sichuan dropped from 2,640,000 families,李心傳 Li, "建炎以來朝野雜記", 文海出版公司 Wenhai, 1967. 1st set, section 7, page 15 as recorded from the census taken in 1162 AD, to 120,000 families李心傳 Li, "建炎以來朝野雜記", 文海出版公司 Wenhai, 1967. 1st set, section 7, page 16 in 1282 AD.C. P. Atwood-Encyclopedia of Mongolia and the Mongol Empire Possible causes include forced population transfer to nearby areas, evacuation to nearby provinces, census under-reporting or inaccuracy, and war-related deaths.
One instance of the deportation of Sichuanese civilians to Mongolia occurred in the aftermath of a battle in 1259 when more than 80,000 people were taken captive from one city in Sichuan and moved to Mongolia.
During the Ming dynasty, major architectural works were created in Sichuan. Buddhism remained influential in the region. Bao'en Temple is a well-preserved 15th-century monastery complex built between 1440 and 1446 during the Zhengtong Emperor's reign (1427–64). Dabei Hall enshrines a thousand-armed wooden image of Guanyin and Huayan Hall is a repository with a revolving sutra cabinet. The wall paintings, sculptures, and other ornamental details are masterpieces of the Ming period.
In the middle of the 17th century, the peasant rebel leader Zhang Xianzhong (1606–1646) from Yan'an, Shaanxi Province, nicknamed Yellow Tiger, led his peasant troop from north China to the south and conquered Sichuan. Upon capturing it, he declared himself emperor of the Daxi dynasty (大西王朝). In response to the resistance from local elites, he massacred a large number of people in Sichuan, killing around one in three people. from J.B. Parsons, The Peasant Rebellions of the Late Ming Dynasty (University of Arizona Press). 1970 As a result of the massacre as well as years of turmoil during the Ming-Qing transition, the population of Sichuan fell sharply, requiring massive resettlement of people from the neighboring Huguang Province (modern Hubei and Hunan) and other provinces during the Qing dynasty.
During the Qing dynasty, Sichuan was merged with Shaanxi and Shanxi to create "Shenzhuan" during 1680–1731 and 1735–1748. The current borders of Sichuan (which then included Chongqing) were established in the early 18th century. In the aftermath of the Sino-Nepalese War on China's southwestern border, the Qing gave Sichuan's provincial government direct control over the minority-inhabited areas of Sichuan west of Kangding, which had previously been handled by an amban.
A landslide dam on the Dadu River caused by an earthquake gave way on 10 June 1786. The resulting flood killed 100,000 people.Schuster, R.L. and G. F. Wieczorek, "Landslide triggers and types" in Landslides: Proceedings of the First European Conference on Landslides 2002 A.A. Balkema Publishers. p.66 [3]
In the 20th century, as Beijing, Shanghai, Nanjing, and Wuhan had all been occupied by the Japanese during the Second Sino-Japanese War, the capital of the Republic of China had been temporarily relocated to Chongqing, then a major city in Sichuan. An enduring legacy of this move is those nearby inland provinces, such as Shaanxi, Gansu, and Guizhou, which previously never had modern Western-style universities, began to be developed in this regard. The difficulty of accessing the region overland from the eastern part of China and the foggy climate hindering the accuracy of the Sichuan invasion of the Sichuan Basin made the region the stronghold of Chiang Kai-shek's Kuomintang government during 1938–45 and led to the Bombing of Chongqing.
The Second Sino-Japanese War was soon followed by the resumed Chinese Civil War, and the cities of East China are obtained by the Communists one after another, the Kuomintang government again tried to make Sichuan its stronghold on the mainland, although it already saw some Communist activity since it was one area on the road of the Long March. Chiang Kai-shek himself flew to Chongqing from Taiwan in November 1949 to lead the defense. But the same month Chongqing switched to the Communists, followed by Chengdu on 10 December. The Kuomintang general Wang Sheng wanted to stay behind with his troops to continue the anticommunist guerilla war in Sichuan, but was recalled to Taiwan. Many of his soldiers made their way there as well, via Burma.
The province was deeply affected by the Great Chinese Famine of 1959–1961, during which period some 9.4 million people (13.07% of the population at the time) died.
In 1978, when Deng Xiaoping took power, Sichuan was one of the first provinces to experiment with the market economic enterprise.
From 1955 until 1997, Sichuan had been China's most populous province; the population hit the 100 million mark shortly after the 1982 census figure of 99,730,000. This changed in 1997 when the Sub-provincial city of Chongqing as well as the three surrounding prefectures of Fuling, Wanxian, and Qianjiang were split off into the new Chongqing. The new municipality was formed to spearhead China's effort to economically develop its western provinces, as well as to coordinate the resettlement of residents from the reservoir areas of the Three Gorges Dam project.
In 1997, when Sichuan split, the sum of the two parts was recorded to be 114,720,000 people. As of 2010, Sichuan ranks as both the 3rd largest (the largest among Chinese provinces with a population greater than 50 million) and 4th most populous province in China.
On 12 May 2008, an earthquake with a magnitude of 7.9/8.0 hit just northwest of the provincial capital of Chengdu. Official figures recorded a death toll of over 87,000 people, and millions of people were left homeless., and
The twenty prefectures of Sichuan are subdivided into 183 county-level divisions (53 districts, 17 county-level cities, 109 counties, and 4 autonomous counties). At the end of the year 2017, the total population is 83.02 million.
The Yangtze River and its tributaries flow through the mountains of western Sichuan and the Sichuan Basin; thus, the province is upstream of the great cities that stand along the Yangtze River further to the east, such as Chongqing, Wuhan, Nanjing, and Shanghai. One of the major tributaries of the Yangtze within the province is the Min River of central Sichuan, which joins the Yangtze at Yibin. There are also a number of other rivers, such as the Jialing River, Tuo River, Yalong River, Wu River, and Jinsha River, and any four of the various rivers are often grouped as the "four rivers" that the name of Sichuan is commonly and mistakenly believed to mean.
Sichuan borders Qinghai to the northwest, Gansu to the north, Shaanxi to the northeast, Chongqing to the east, Guizhou to the southeast, Yunnan to the south, and the Tibet Autonomous Region to the west.
The western region has mountainous areas producing a cooler but sunnier climate. Having cool to very cold winters and mild summers, temperatures generally decrease with greater elevation. Due to high altitude and inland location, the far northwestern areas like Garzê County and Zoigê County exhibit a subalpine climate (Köppen Dwc) or even an alpine climate ( ETH), featuring frigid winters down to and even cold summer nights. The region is geologically active with landslides and earthquakes. Average elevation ranges from ; average temperatures range from .
The southern part of the province, including Panzhihua and Xichang, has a sunny climate with short, very mild winters and very warm to hot summers.
The governor of Sichuan is the highest-ranking official in the People's Government of Sichuan. However, in the province's dual party-government governing system, the Governor has less power than the Party Secretary of Sichuan, colloquially termed the "Sichuan CCP Party Chief".
The is the primary law enforcement agency in Sichuan. It has a SWAT unit, a forestry unit, an anti-drug unit, an economic crime unit, a food safety unit and an investigation unit. 2021 年度四川省公安厅(本级)单位决算 2021, retrieved 12/3/2025 In 2021, the agency had a budget of 45.8 million Renminbi.
On July 10, 2017, the Sichuan Provincial Public Security Department established the Sichuan Provincial Expressways Public Security Bureau (c=四川高速公路公安局), a provincial Highway patrol agency.
The provides paramilitary law enforcement and disaster relief services within Sichuan province. The Yibin Detachment was deployed for disaster relief during the of February 8, 2025 in Junlian County, Yibin.
The Sichuan Provincial Fire and Rescue Department (c=四川省消防救援总队) is in charge of firefighting and rescue duties within the province.
Sichuan has been historically known as the "Province of Abundance". It is one of the major agricultural production bases of China. Grain, including rice and wheat, is the major product with output that ranked first in China in 1999. Commercial crops include citrus fruits, sugar cane, sweet potatoes, peaches, and grapes. Sichuan also had the largest output of pork among all the provinces and the second largest output of silkworm cocoons in 1999. Sichuan is rich in mineral resources. It has more than 132 kinds of proven underground mineral resources including vanadium, titanium, and lithium is the largest in China. The Panxi region alone possesses 13.3% of the reserves of iron, 93% of titanium, 69% of vanadium, and 83% of cobalt in the whole country. Sichuan also possesses China's largest proven natural gas reserves (such as the Dazhou and Yuanba gas fields), the majority of which are transported to more developed eastern regions.
Sichuan is one of the major industrial centers of China. It was a major recipient of China's investment in industrial capacity during the Third Front campaign. In addition to heavy industries such as coal, energy, iron, and steel, the province has also established a light industrial sector comprising building materials, wood processing, food, and silk processing. Chengdu and Mianyang are the production centers for textiles and electronics products. Deyang, Panzhihua, and Yibin are the production centers for machinery, metallurgical industries, and wine, respectively. Sichuan's wine production accounted for 21.9% of the country's total production in 2000.
Great strides have been made in developing Sichuan into a modern hi-tech industrial base, by encouraging both domestic and foreign investments in electronics and information technology (such as software), machinery and metallurgy (including automobiles), hydropower, pharmaceutical, food and beverage industries.
The auto industry is an important and key sector of the machinery industry in Sichuan. Most of the auto manufacturing companies are located in Chengdu, Mianyang, Nanchong, and Luzhou.
Other important industries in Sichuan include aerospace and defense (military) industries. A number of China's rockets (Long March rockets) and were launched from the Xichang Satellite Launch Center, located in the city of Xichang.
Sichuan's landscapes and rich historical relics have also made the province a center for tourism.
The Three Gorges Dam, the largest dam ever constructed, was built on the Yangtze River in nearby Hubei province to control flooding in the Sichuan Basin, neighboring Yunnan province, and downstream. The plan is hailed by some as China's efforts to shift towards alternative energy sources and to further develop its industrial and commercial bases, but has been denounced for mass resettlement, loss of archeological sites, and ecological damage.
In 2020, the Chengdu Hi-Tech Comprehensive Free Trade Zone achieved a total import and export volume of 549.1 billion yuan (including the Shuangliu Sub-zone), accounting for 68% of the province's total foreign trade import and export volume, ranking first in the national comprehensive insurance zone import and export volume for three consecutive years.
Chengdu Hi-tech Development Zone covers an area of , consisting of South Park and West Park. By relying on the city sub-center, which is under construction, South Park is focusing on creating a modernized industrial park of science and technology with scientific and technological innovation, incubation R&D, modern service industry, and Headquarters economy playing leading roles. Priority has been given to the development of the software industry. Located on both sides of the "Chengdu-Dujiangyan-Jiuzhaigou" golden tourism channel, the West Park aims at building a comprehensive industrial park targeting industrial clustering with complete supportive functions. West Park gives priority to three major industries i.e. electronic information, biomedicine, and precision machinery.
The zone is a leader in the electronic information industry, biological medicine, new materials, and the production of motor vehicles and parts.
Chengdu airports are also 144-hour transit visa-free airports for foreigners from 53 countries.
Sichuan was China's most populous province before Chongqing became a directly controlled municipality; it is currently the fourth most populous, after Guangdong, Shandong, and Henan. As of 1832, Sichuan was the most populous of the 18 provinces in China, with an estimated population at that time of 21 million. It was the third most populous sub-national entity in the world, after Uttar Pradesh, India, and the Russian Soviet Federative Socialist Republic until 1991, when the Soviet Union was dissolved. It is also one of the only eight subnational divisions to ever reach 100 million people (Uttar Pradesh, Russian RSFSR, Maharashtra, Sichuan, Bihar, Shandong, Guangdong, and Punjab). It is currently ranked 10th.
The reports did not give figures for other types of religion; the vast majority may be either irreligious or involved in Chinese folk religion, Buddhism, etc. Tibetan Buddhism is widespread, especially in areas inhabited by ethnic Tibetans. Sichuan is one of the cradles of the early Zhengyi Taoism.
According to "Vestiges of Zoroastrianism in Medieval Sichuan" by Yao Chongxin, professor at Sun Yat-sen University, Zoroastrianism flourished during the period of Tang dynasty (618–907), Former Shu (907–925), Later Shu (934–965), and Song dynasty (960–1279).
A Chabad house was established in Chengdu in 2012, after moving five times, a permanent location was secured at Wuhou District.
During the Yuan dynasty and Ming dynasty dynasties, the population of the area was reduced through wars and the bubonic plague, and settlers arrived from the area of modern Hubei, replacing the earlier common Chinese with a new standard.
The Li Bai Memorial, located in Jiangyou, is a museum in memory of Li Bai, a Chinese poet of Tang dynasty (618–907) built at the place where he grew up. The building was begun in 1962 on the occasion of the 1200th anniversary of his death, completed in 1981, and opened to the public in October 1982. The memorial is built in the style of the classic Tang garden.
In 2003, Sichuan had "88 art performing troupes, 185 culture centers, 133 libraries, and 52 museums". Companies based in Sichuan also produced 23 television series and one film.
The languages of Sichuan are primarily members of three subfamilies of the Sino-Tibetan languages.
The most widely used variety of Chinese spoken in Sichuan is Sichuanese, which is the lingua franca in Sichuan, Chongqing, and parts of the Tibet Autonomous Region. Although Sichuanese is generally classified as a dialect of Mandarin Chinese, it is highly divergent in phonology, vocabulary, and even grammar from Standard Chinese.
Garzê Tibetan Autonomous Prefecture and Ngawa Tibetan and Qiang Autonomous Prefecture in western Sichuan are populated by Tibetan people and Qiang people. Tibetans speak the Khams Tibetan and Amdo Tibetan, which are Tibetic languages, as well as various Qiangic languages. The Qiang speak Qiangic languages and often Tibetic languages as well. The Yi people of Liangshan Yi Autonomous Prefecture in southern Sichuan speak the Nuosu language, which is one of the Lolo-Burmese languages; Yi is written using the Yi script, a syllabary standardized in 1974. The Southwest University for Nationalities has one of China's most prominent Tibetology departments and the Southwest Minorities Publishing House prints literature in minority languages. In the minority-inhabited regions of Sichuan, there is bilingual signage and public school instruction in non-Mandarin minority languages.
Another famous Sichuan delicacy is hot pot. Hot pot is a Chinese soup containing a variety of East Asian foodstuffs and ingredients, prepared with a simmering pot of soup stock at the dining table. While the hot pot is kept simmering, ingredients are placed into the pot and cooked at the table. Typical hot pot dishes include thinly sliced meat, leaf vegetables, mushrooms, wontons, egg dumplings, tofu, and seafood. The cooked food is usually eaten with a dipping sauce.
As of July 2013, the world's largest building, the New Century Global Center is located in Chengdu. At high, long, and wide, the Center houses retail outlets, movie theaters, offices, hotels, the Paradise Island waterpark, an artificial beach, a -long LED screen, skating rink, pirate ship, fake Mediterranean village, 24-hour artificial sun, and 15,000-spot parking area.
