Chongqing (/ˌtʃʊŋˈtʃɪŋ/, also US: /ˌtʃɔːŋ-, ˌtʃuːŋ-/,^[24][25][26] Chinese: [ʈʂʰʊ̌ŋ.tɕʰîŋ] (listen)), alternately romanized as Chungking,^[13] is a major city in southwest China. Administratively, it is one of the four municipalities under the direct administration of central government of the People's Republic of China (the other three are Beijing, Shanghai and Tianjin), and the only such municipality located far away from the coast.^[27] It is the largest city proper in the world.

Chongqing was a municipality during the Republic of China (ROC) administration, serving as its wartime capital during the Second Sino-Japanese War (1937–1945); during this period, Chongqing was listed as one of the world's four anti-fascist command centers, along with Washington, D.C., London and Moscow.^[28] The current municipality was recreated on 14 March 1997 to help develop the central and western parts of China.^[29] The Chongqing administrative municipality has a population of over 30 million, spread over an area the size of Austria.^[30] The city of Chongqing made of 9 urban and suburban districts has a population of 8,518,000 as of 2016.^[18] According to the 2010 census, Chongqing is the most populous Chinese municipality,^[31] and also the largest direct-controlled municipality in China, containing 26 districts, eight counties, and four autonomous counties.

The official abbreviation of the city, "Yú" (渝), was approved by the State Council on 18 April 1997.^[32] This abbreviation is derived from the old name of a part of the Jialing River that runs through Chongqing and feeds into the Yangtze River.

Chongqing has a significant history and culture. Being one of China's National Central Cities, it serves as the economic centre of the upstream Yangtze basin. It is a major manufacturing centre and transportation hub; a July 2012 report by the Economist Intelligence Unit described it as one of China's "13 emerging megalopolises".^[33]

Tradition associates Chongqing with the State of Ba. This new capital was first named Jiangzhou (江州).^[34]

Jiangzhou subsequently remained under Qin Shi Huang's rule during the Qin dynasty, the successor of the Qin State, and under the control of Han dynasty emperors. Jiangzhou was subsequently renamed during the Northern and Southern dynasties to Chu Prefecture (楚州), then in 581 AD (Sui dynasty) to Yu Prefecture (渝州), and later in 1102 during Northern Song to Gong Prefecture (恭州).^[35] The name Yu however survives to this day as an abbreviation for Chongqing, and the city centre where the old town stood is also called Yuzhong (Central Yu).^[34] It received its current name in 1189, after Prince Zhao Dun of the Southern Song dynasty described his crowning as king and then Emperor Guangzong as a "double celebration" (simplified Chinese: 双重喜庆; traditional Chinese: 雙重喜慶; pinyin: shuāngchóng xǐqìng, or chongqing in short). In his honour, Yu Prefecture was therefore renamed Chongqing subprefecture marking the occasion of his enthronement.

In 1362, (Yuan dynasty), Ming Yuzhen, a peasant rebel leader, established the Daxia Kingdom (大夏) at Chongqing for a short time.^[36] In 1621 (Ming dynasty), another short-lived kingdom of Daliang (大梁) was established by She Chongming (奢崇明) with Chongqing as its capital.^[37] In 1644, after the fall of the Ming dynasty to a rebel army, Chongqing, together with the rest of Sichuan, was captured by Zhang Xianzhong, who was said to have massacred a large number of people in Sichuan and depopulated the province, in part by causing many people to flee to safety elsewhere. The Manchus later conquered the province, and during the Qing dynasty, immigration to Chongqing and Sichuan took place with the support of the Qing emperor.^[38]

In 1890, the British Consulate General was opened in Chongqing.^[39] The following year, the city became the first inland commerce port open to foreigners.^[40] The French, German, US and Japanese consulates were opened in Chongqing in 1896–1904.^{[41][42][43][44]}

During and after the Second Sino-Japanese War, from Nov 1937 to May 1946, it was Generalissimo Chiang Kai-shek's provisional capital. After Britain, the United States, and other Allies entered the war in Asia in December 1941, one of the Allies' deputy commanders of operations in South East Asia (South East Asia Command SEAC), Joseph Stilwell, was based in the city. The city was also visited by Lord Louis Mountbatten, the Supreme Commander of SEAC which was itself headquartered in Ceylon, modern day Sri Lanka. Chiang Kai Shek as Supreme Commander in China worked closely with Stilwell.^[45] The Japanese Air Force heavily bombed it. Due to its mountainous environment, many people were saved from the bombing. Due to the bravery, contributions and sacrifices made by the local people during World War II, Chongqing became known as the City of Heroes. Many factories and universities were relocated from eastern China to Chongqing during the war, transforming this city from inland port to a heavily industrialized city. In late November 1949 the Nationalist KMT government fled the city.^[46]

On 14 March 1997, the Eighth National People's Congress decided to merge the Sub-provincial city with the neighbouring Fuling, Wanxian, and Qianjiang prefectures that it had governed on behalf of the province since September 1996. The resulting single division became Chongqing Municipality, containing 30,020,000 people in forty-three former counties (without intermediate political levels). The municipality became the spearhead of China's effort to develop its western regions and to coordinate the resettlement of residents from the reservoir areas of the Three Gorges Dam project. Its first official ceremony took place on 18 June 1997. On 8 February 2010, Chongqing became one of the four National Central/Core cities, the other three are Beijing, Shanghai and Tianjin.^[47] On 18 June 2010, Liangjiang New Area was established in Chongqing, which is the third State-level new areas at the time of its establishment.^[48]

Chongqing is situated at the transitional area between the Tibetan Plateau and the plain on the middle and lower reaches of the Yangtze River in the sub-tropical climate zone often swept by moist monsoons. It often rains at night in late spring and early summer, and thus the city is famous for its "night rain in the Ba Mountains", as described by poems throughout Chinese history including the famous Written on a Rainy Night-A Letter to the North by Li Shangyin.^[49] The municipality reaches a maximum width of 470 kilometres (290 mi) from east to west, and a maximum length of 450 km (280 mi) from north to south.^[50] It borders the following provinces: Hubei in the east, Hunan in the southeast, Guizhou in the south, Sichuan in the west and northwest, and Shaanxi to the north in its northeast corner.^[51]

Chongqing covers a large area crisscrossed by rivers and mountains. The Daba Mountains stand in the north, the Wu Mountains in the east, the Wuling Mountains in the southeast, and the Dalou Mountains in the south. The whole area slopes down from north and south towards the Yangtze River valley, with sharp rises and falls. The area is featured by a large geological massif, of mountains and hills, with large sloping areas at different heights.^[52] Typical karst landscape is common in this area, and stone forests, numerous collections of peaks, limestone caves and valleys can be found in many places. The Longshuixia Gap (龙水峡地缝), with its natural arch-bridges, has made the region a popular tourist attraction. The Yangtze River runs through the whole area from west to east, covering a course of 665 km (413 mi), cutting through the Wu Mountains at three places and forming the well-known Three Gorges: the Qutang, the Wuxia and the Xiling gorges.^[53] Coming from northwest and running through "the Jialing Lesser Three Gorges" of Libi, Wentang and Guanyin, the Jialing River joins the Yangtze in Chongqing.^[54]

The central urban area of Chongqing, or Chongqing proper, is a city of unique features. Built on mountains and partially surrounded by the Yangtze and Jialing rivers, it is known as a "mountain city" and a "city on rivers".^[55] The night scene of the city is very illuminated, with millions of lights and their reflection on the rivers. With its special topographical features, Chongqing has the unique scenery of mountains, rivers, forests, springs, waterfalls, gorges, and caves. Li Bai, a famous poet of the Tang dynasty, was inspired by the natural scenery and wrote this epigram.^[56]

Specifically, the central urban area is located on a huge folding area. Yuzhong District, Nan'an District, Shapingba District and Jiangbei District are located right on a big syncline. And the "Southern Mountain of Chongqing" (Tongluo Mountain), along with the Zhongliang Mountain are two anticlines next to the syncline of downtown.^[57]

Zhongliang Mountains (中梁山) and Tongluo Mountains (铜锣山) roughly forms the eastern and western boundaries of Chongqing's urban area. The highest point in downtown is the top of Eling Hill, which is a smaller syncline hill that keeps Yangtze River and Jialing River apart for some more kilometres. The elevation of Eling Hill is 379 metres (1,243 feet). The lowest point is Chaotian Gate, where the two rivers merge with each other. The altitude there is 160 metres (520 feet). The average height of the area is 259 metres (850 feet). However, there are several high mountains outside central Chongqing, such as the Wugong Ling Mountain, with the altitude of 1,709.4 metres (5,608 feet), in Jiangjin.

All climatic data listed below comes from the central parts of the city.

Chongqing has a humid subtropical climate (Köppen Cfa), bordering on a monsoonal humid subtropical climate (Köppen Cwa) and for most of the year experiences very high relative humidity, with all months above 75%. Known as one of the "Three Furnaces" of the Yangtze river, along with Wuhan and Nanjing, its summers are long and among the hottest and most humid in China, with highs of 33 to 34 °C (91 to 93 °F) in July and August in the urban area.^[61] Winters are short and somewhat mild, but damp and overcast. The city's location in the Sichuan Basin causes it to have one of the lowest annual sunshine totals nationally, at only 1,055 hours, lower than much of Northern Europe; the monthly percent possible sunshine in the city proper ranges from a mere 8% in December and January to 48% in August. Extremes since 1951 have ranged from −1.8 °C (29 °F) on 15 December 1975 (unofficial record of −2.5 °C (27 °F) was set on 8 February 1943) to 43.0 °C (109 °F) on 15 August 2006 (unofficial record of 44.0 °C (111 °F) was set on 8 and 9 August 1933).^[59][62]

As exemplified by Youyang County below, conditions are often cooler in the southeast part of the municipality due to the higher elevations there.

Chongqing, with over 100 days of fog per year,^[64] is known as the "Fog City" (雾都), like San Francisco, and a thick layer of fog shrouds it for 68 days per year during the spring and autumn.^[65][66] During the Second Sino-Japanese War, this special weather possibly played a role in protecting the city from being overrun by the Imperial Japanese Army.

Chongqing is the largest of the four direct-controlled municipalities of the People's Republic of China. The municipality is divided into 38 subdivisions (3 were abolished in 1997, and Wansheng and Shuangqiao districts were abolished in October 2011^[67]), consisting of 26 districts, 8 counties, and 4 autonomous counties. The boundaries of Chongqing municipality reach much farther into the city's hinterland than the boundaries of the other three provincial level municipalities (Beijing, Shanghai and Tianjin), and much of its administrative area, which spans over 80,000 square kilometres (30,900 sq mi), is rural. At the end of year 2017, the total population is 30.75 million.[1] ^[186]

a Indicates with which district the division was associated below prior to the merging of Chongqing, Fuling, Wanxian (now Wanzhou) and Qianjiang in 1997.

The main urban area of Chongqing city (重庆主城区) spans approximately 5,473 square kilometres (2,113 square miles), and includes the following nine districts:^[73][74]

According to a July 2010 article from the official Xinhua news agency, the municipality has a population of 32.8 million, including 23.3 million farmers. Among them, 8.4 million farmers have become migrant workers, including 3.9 million working and living in urban areas of Chongqing.^[78] The metropolitan area encompassing the central urban area was estimated by the OECD (Organisation for Economic Co-operation and Development) to have, as of 2010, a population of 17 million.^[79][80]

This would mean that the locally registered farmers who work in other jurisdictions number 4.5 million, reducing the local, year-round population of Chongqing in 2010 to 28.3 million, plus those who are registered in other jurisdictions but live and work in Chongqing. According to China's 2005 statistical yearbook, of a total population of 30.55 million, those with residence registered in other jurisdictions but residing in the Chongqing enumeration area numbered 1.4 million, including 46,000 who resided in Chongqing "for less than half-year". An additional 83,000 had registered in Chongqing, but not yet settled there.^[81]

The 2005 statistical yearbook also lists 15.22 million (49.82%) males and 15.33 million (50.18%) females.^[81]

In terms of age distribution in 2004, of the 30.55 million total population, 6.4 million (20.88%) were age 0–14, 20.7 million (67.69%) were 15–64, and 3.5 million (11.46%) were 65 and over.^[82]

Of a total 10,470,000 households (2004), 1,360,000 consisted of one person, 2,940,000 two-person, 3,190,000 three-person, 1,790,000 four-person, 783,000 five-person, 270,000 six-person, 89,000 seven-person, 28,000 eight-person, 6,000 nine-person, and 10,000 households of 10 or more persons per household.^[83]

In the first decade of the 21st century, the city became notorious for organised crime and corruption. Gangsters oversaw businesses involving billions of yuan and the corruption reached into the law-enforcement and justice systems. In 2009, city authorities under the auspices of municipal Communist Party secretary Bo Xilai undertook a large-scale crackdown, arresting 4,893 suspected gangsters, "outlaws" and corrupt cadres, leading to optimism that the period of gangsterism was over.^[84] However, local media later highlighted the apparent reliance by the authorities on torture to extract confessions upon which convictions were based. In December 2009, one defence lawyer was controversially arrested and sentenced to 18 months in prison for "coaching his client to make false claims of torture" and in July 2010, another lawyer released videotapes of his client describing the torture in detail.^[85] In 2014, four policemen involved in the interrogation were charged with the practice of "opposed illegal interrogation techniques", considered by observers to be torture.^[86]

Chongqing has been, since 1997, a direct-controlled municipality in the Chinese administrative structure, making it a provincial-level division with commensurate political importance. The municipality's top leader is the secretary of the municipal committee of the Communist Party of China ("party chief"), which, since 2007, has also held a seat on the Politburo of the Communist Party of China, the country's second highest governing council. Under the Soviet-inspired nomenklatura system of appointments, individuals are appointed to the position by the central leadership of the Communist Party, and bestowed to an official based on seniority and adherence to party orthodoxy, usually given to an individual with prior regional experience elsewhere in China and nearly never a native of Chongqing. Notable individuals who have held the municipal Party Secretary position include He Guoqiang, Wang Yang, Bo Xilai, Zhang Dejiang, and Sun Zhengcai, the latter three were Politburo members during their term as party chief. The party chief heads the municipal party standing committee, the de facto top governing council of the municipality. The standing committee is typically composed of 13 individuals which includes the party chiefs of important subdivisions and other leading figures in the local party and government organization, as well as one military representative.

The municipal People's Government serves as the day-to-day administrative authority, and is headed by the mayor, who is assisted by numerous vice mayors and mayoral assistants. Each vice mayor is given jurisdiction over specific municipal departments. The mayor is the second-highest-ranking official in the municipality. The mayor usually represents the city when foreign guests visit.^[87]

The municipality also has a People's Congress, theoretically elected by lower level People's Congresses. The People's Congress nominally appoints the mayor and approves the nominations of other government officials. The People's Congress, like those of other provincial jurisdictions, is generally seen as a symbolic body. It convenes in full once a year to approve party-sponsored resolutions and local regulations and duly confirm party-approved appointments. On occasion the People's Congress can be venues of discussion on municipal issues, although this is dependent on the actions of individual delegates. The municipal People's Congress is headed by a former municipal official, usually in their late fifties or sixties, with a lengthy prior political career in Chongqing. The municipal Political Consultative Conference (zhengxie) meets at around the same time as the People's Congress. Its role is to advise on political issues. The zhengxie is headed by a leader who is typically a former municipal or regional official with a lengthy career in the party and government bureaucracy.

Chongqing was the wartime capital of China during the Second Sino-Japanese war (i.e., World War II), and from 1938 to 1946,^[88] the seat of administration for the Republic of China's government before its departure to Nanjing and then Taiwan.^[89] It also contains a military museum named after the Chinese Korean War hero Qiu Shaoyun.^[90]

Chongqing used to be the headquarters of the 13th Group Army of the People's Liberation Army, one of the two group armies that formerly comprise the Chengdu Military Region, which in 2016 was re-organized into the Western Theater Command.^[91]

Chongqing was separated from Sichuan province and made into a municipality in its own right in 14 March 1997^[92] in order to accelerate its development and subsequently China's relatively poorer western areas (see China Western Development strategy).^[93] An important industrial area in western China,^[94] Chongqing is also rapidly urbanising. For instance, statistics^[95] suggest that new construction added approximately 137,000 square metres (1,470,000 square feet) daily of usable floor space to satisfy demands for residential, commercial and factory space. In addition, more than 1,300 people moved into the city daily, adding almost 100 million yuan (US$15 million) to the local economy.

Traditionally, due to its geographical remoteness, Chongqing and neighbouring Sichuan have been important military bases in weapons research and development.^[96] Chongqing's industries have now diversified but unlike eastern China, its export sector is small due to its inland location. Instead, factories producing local-oriented consumer goods such as processed food, cars, chemicals, textiles, machinery and electronics are common.

Chongqing is China's third largest centre for motor vehicle production and the largest for motorcycles. In 2007, it had an annual output capacity of 1 million cars and 8.6 million motorcycles.^[97] Leading makers of cars and motor bikes includes China's fourth biggest automaker; Changan Automotive Corp and Lifan Hongda Enterprise, as well as Ford Motor Company, with the US car giant having 3 plants in Chongqing. The municipality is also one of the nine largest iron and steel centres in China and one of the three major aluminium producers. Important manufacturers include Chongqing Iron and Steel Company and South West Aluminium which is Asia's largest aluminium plant.^[98] Agriculture remains significant. Rice and fruits, especially oranges, are the area's main produce. Natural resources are also abundant with large deposits of coal, natural gas, and more than 40 kinds of minerals such as strontium and manganese. Coal reserves ≈ 4.8 billion tonnes. Chuandong Natural Gas Field is China's largest inland gas field with deposits of around 270 billion m3 – more than 1/5 of China's total. Has China's largest reserve of strontium (China has the world's 2nd biggest strontium deposit). Manganese is mined in the Xiushan area. although the mining sector has been criticised for being wasteful, heavily polluting and unsafe.^[99] Chongqing is also planned to be the site of a 10 million ton capacity refinery operated by CNPC (parent company of PetroChina) to process imported crude oil from the Sino-Burma pipelines. The pipeline itself, though not yet finished, will eventually run from Sittwe (in Myanmar's western coast) through Kunming in Yunnan before reaching Chongqing^[100] and it will provide China with fuels sourced from Myanmar, the Middle East and Africa. Recently, there has been a drive to move up the value chain by shifting towards high technology and knowledge intensive industries resulting in new development zones such as the Chongqing New North Zone (CNNZ).^[101] Chongqing's local government is hoping through the promotion of favorable economic policies for the electronics and information technology sectors, that it can create a 400 billion RMB high technology manufacturing hub which will surpass its car industry and account for 25% of its exports.^[102]

The city has also invested heavily in infrastructure to attract investment.^[97][103] The network of roads and railways connecting Chongqing to the rest of China has been expanded and upgraded reducing logistical costs. Furthermore, the nearby Three Gorges Dam which is the world's largest, will not only supply Chongqing with power once completed but also allows oceangoing ships to reach Chongqing's Yangtze River port.^[104] These infrastructure improvements have led to the arrivals of numerous foreign direct investors (FDI) in industries ranging from car to finance and retailing; such as Ford,^[105] Mazda,^[106] HSBC,^[107] Standard Chartered Bank,^[108] Citibank,^[109] Deutsche Bank,^[110] ANZ Bank,^[111] Scotiabank,^[112] Wal-Mart,^[113] Metro AG^[114] and Carrefour,^[115] among other multinational corporations.

Chongqing's nominal GDP in 2011 reached 1001.1 billion yuan (US$158.9 billion) while registering an annual growth of 16.4%. However, its overall economic performance is still lagging behind eastern coastal cities such as Shanghai. For instance, its per capita GDP was 22,909 yuan (US$3,301) which is below the national average. Nevertheless, there is a massive government support to transform Chongqing into the region's economic, trade, and financial centre and use the municipality as a platform to open up the country's western interior to further development.^[116]

Chongqing has been identified by the Economist Intelligence Unit in the November 2010 Access China White Paper as a member of the CHAMPS (Chongqing, Hefei, Anshan, Maanshan, Pingdingshan and Shenyang), an economic profile of the top 20 emerging cities in China.^[117]

The city includes a number of economic and technological development zones:

Chongqing itself is part of the West Triangle Economic Zone, along with Chengdu and Xi'an.

Since its elevation to national-level municipality in 1997, the city has dramatically expanded its transportation infrastructure. With the construction of railways and expressways to the east and southeast, Chongqing is a major transportation hub in southwestern China.

As of October 2014, the municipality had 31 bridges across the Yangtze River including over a dozen in the city's urban core.^[126] Aside from the city's first two Yangtze River bridges, which were built, respectively, in 1960 and 1977, all of the other bridges were completed since 1995.

Chongqing is one of the most important inland ports in China. There are numerous luxury cruise ships that terminate at Chongqing, cruising downstream along the Yangtze River to Yichang, Wuhan, Nanjing or even Shanghai.^[127] In the recent past, this provided virtually the only transportation option along the river. However, improved rail, expressways and air travel have seen this ferry traffic reduced or cancelled altogether. Most of the river ferry traffic consists of leisure cruises for tourists rather than local needs. Improved access by larger cargo vessels has been made due to the construction of the Three Gorges Dam. This allows bulk transport of goods along the Yangtze River. Coal, raw minerals and containerized goods provide the majority of traffic plying this section of the river. Several port handling facilities exists throughout the city, including many impromptu river bank sites.^[128]

Major train stations in Chongqing:

Chongqing is a major freight destination for rail with continued development with improved handling facilities. Due to subsidies and incentives, the relocation and construction of many factories in Chongqing has seen a huge increase in rail traffic.

Chongqing is a major rail hub regionally.

Traditionally, the road network in Chongqing has been narrow, winding and limited to smaller vehicles because of the natural terrain, large rivers and the huge population demands on the area, especially in the Yuzhong District. In other places, such as Jiangbei, large areas of homes and buildings have recently been cleared to improve the road network and create better urban planning. This has seen many tunnels and large bridges needing to be built across the city. Construction of many expressways have connected Chongqing to neighbouring provinces. Several ring roads have also been constructed. The natural mountainous terrain that Chongqing is built on makes many road projects difficult to construct, including for example some of the world's highest road bridges.^[129]

Unlike many other Chinese cities, it is rare for motorbikes, electric scooters or bicycles to be seen on Chongqing Roads. This is due to the extremely hilly and mountainous nature of Chongqing's roads and streets. However, despite this, Chongqing is a large manufacturing centre for these types of vehicles.^[130]

The major airport of Chongqing is Chongqing Jiangbei International Airport (IATA: CKG, ICAO: ZUCK). It is located in Yubei District. The airport offers a growing network of direct flights to China, South East Asia, the Middle East, North America, and Europe. It is located 21 km (13 mi) north of the city-centre of Chongqing and serves as an important aviation hub for south-western China.^[131] Jiangbei airport is a hub for China Southern Airlines, Chongqing Airlines, Sichuan Airlines, China Express Airlines, Shandong Airlines and Hainan Airlines's new China West Air. Chongqing also is a focus city of Air China, therefore it is very well connected with Star Alliance and Skyteam's international network. The airport currently has three parallel runways in operation. It serves domestic routes to most other Chinese cities, as well as international routes to Auckland, New York City, London, Los Angeles, Moscow, Doha, Dubai, Seoul, Bangkok, Phuket, Osaka, Singapore, Chiang Mai, Phnom Penh, Siem Reap, Malé, Bali, Tokyo, Kuala Lumpur, Batam, Rome and Helsinki. As of 2018, Jiangbei Airport is the 9th busiest airport in terms of passenger traffic in mainland China.^[132]

Currently, Jiangbei airport has three terminals. Chongqing Airport has metro access (CRT Line 3 and Line 10) to its central city, and two runways in normal use.^[133]

There are two other airports in Chongqing Municipality: Qianjiang Wulingshan Airport (IATA: JIQ, ICAO: ZUQJ) and Wanzhou Wuqiao Airport (IATA: WXN, ICAO: ZUWX). They are both class 4C airports and serve passenger flights to some domestic destinations including Beijing, Shanghai and Kunming. Two more airports are being constructed soon: Wulong Xiannüshan Airport and Wushan Shennüfeng Airport.

Public transport in Chongqing consists of metro, intercity railway, a ubiquitous bus system and the world's largest monorail network.

According to the Chongqing Municipal Government's ambitious plan in May 2007, Chongqing is investing 150 billion RMB over 13 years to finish a system that combines underground metro lines with heavy monorail (called 'light rail' in China).

As of 2017, four metro lines, the 14 km (8.7 mi) long CRT Line 1, a conventional subway, and the 19 km (12 mi) long heavy monorail CRT Line 2 (through Phase II), Line 3, a heavy monorail connects the airport and the southern part of downtown.,^[134] Line 6, runs between Beibei, a commuter city in the far north to the centre.^[135] Line 5 opened in late 2017.

By 2020 CRT will consist of 6 straight lines and 1 circular line resulting in 363.5 km (225.9 mi) of road and railway to the existing transportation infrastructure and 93 new train stations will be added to the 111 stations that are already in place.^[136]

By 2050, Chongqing will have as many as 18 lines planned to be in operation.^[137]

With so many bridges crossing the Yangtze and Jialing rivers in the urban area, Chongqing is sometimes known as the 'Bridge Capital of China'. The first important bridge in urban Chongqing was the Niujiaotuo Jialing River Bridge, built in 1958. The first bridge over the Yangtze river was the Shibanpo Yangtze River Bridge (or Chongqing Yangtze River Bridge) built in 1977.

As of 2014, within the area of the 9 districts, there were 20 bridges on the Yangtze river and 28 bridges on the Jialing river. The bridges in Chongqing exhibit a variety of shapes and structures, making Chongqing a showcase for bridge design.

Chongqing is the only Chinese city that keeps public aerial tramways. Historically there were three aerial tramways in Chongqing: the Yangtze River Tramway, the Jialing River Tramway and the South Mountain Tramway. Currently, only Yangtze River Tramway is still operating and it is Class 4A Tourist Attractions in China. This tramway is 1,160 metres (3,810 feet) long, connecting the southern and northern banks of Yangtze River. The daily passenger volume is about 10,000.

The language native to Chongqing is Southwestern Mandarin. More precisely, the great majority of the municipality, save for Xiushan, speak Sichuanese, including the primary Chengdu-Chongqing dialect and Minjiang dialect spoken in Jiangjin and Qijiang.^[138] There are also a few speakers of Xiang and Hakka in the municipality, due to the great immigration wave to the Sichuan region (湖广填四川) during the Ming and Qing dynasties. In addition, in parts of southeastern Chongqing, the Miao and Tujia languages are also used by some Miao and Tujia people.^[139]

As the provisional Capital of China for almost ten years (1937 to 1945), the city was also known as one of the three headquarters of the Allies during World War II, as well as being a strategic center of many other wars throughout China's history. Chongqing has many historic war-time buildings or sites, some of which have since been destroyed. These sites include the People's Liberation Monument, located in the center of Chongqing city. It used to be the highest building in the area, but is now surrounded and dwarfed by numerous shopping centres. Originally named the Monument for the Victory over Axis Armies, it is the only building in China for that purpose.^[140] Today, the monument serves as a symbol for the city. The General Joseph W. Stilwell Museum, dedicated to General "Vinegar Joe" Stilwell, a World War II general.^[141] the air force cemetery in the Nanshan area, in memory of those air force personnel killed during the Second Sino-Japanese War (1937–1945), and the Red Rock Village Museum, a diplomatic site for the Communist Party in Chongqing led by Zhou Enlai during World War II, and Guiyuan, Cassia Garden, where Mao Zedong signed the "Double 10 (10 October) Peace Agreement" with the Kuomintang in 1945.^[142]

Chongqing food is part of Sichuan cuisine. Chongqing is known for its spicy food.
