Direct-administered municipality in the context of "Western China"

East China (Chinese: 华东; pinyin: huá dōng) is a geographical region in the People's Republic of China, mainly consisting of seven province-level administrative divisions, namely the provinces (from north to south) Shandong, Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, and the direct-administered municipality Shanghai.

The region was defined in 1945 as the jurisdiction area of the Central Committee's East China Bureau (华东局), which was a merger politburo agency of the Shandong Bureau and the Central China Bureau previously established during the Second Sino-Japanese War. After the founding of the People's Republic of China, the region included all the aforementioned provinces except Jiangxi, which was previously considered part of South Central China before being reassigned in 1961. The East China Bureau was abolished in 1966 due to the Cultural Revolution, but in 1970 the fourth five-year plan redefined the region as the East China Coordinated Region (华东协作区), which supported the logistics of the Jinan and Nanjing Military Regions. This geographical definition was retained after the economic reform of the 1980s.

The People's Republic of China is officially divided into 34 province-level administrative divisions, the first level of administrative division in the country. There are four types of divisions at the province level:

• Provinces (23)
• Autonomous regions (5)
• Municipalities (4)
• Special administrative regions (SARs, 2)

Shanghai is a direct-administered municipality and the most populous urban area in China. The city is located on the Chinese shoreline on the southern estuary of the Yangtze River, with the Huangpu River flowing through it. The population of the city proper is the second largest in the world with around 24.87 million inhabitants in 2023, while the urban area is the most populous in China, with 29.87 million residents. As of 2022, the Greater Shanghai metropolitan area was estimated to produce a gross metropolitan product (nominal) of nearly 13 trillion RMB ($1.9 trillion). Shanghai is one of the world's major centers for finance, business and economics, research, science and technology, manufacturing, transportation, tourism, and culture. The Port of Shanghai is the world's busiest container port.

Originally a fishing village and market town, Shanghai grew to global prominence in the 19th century due to domestic and foreign trade and its favorable port location. The city was one of five treaty ports forced to open to trade with the Europeans after the First Opium War, with the Shanghai International Settlement and French Concession subsequently established. The city became a primary commercial and financial hub of Asia in the 1930s. During the Second World War, it was the site of the Battle of Shanghai. This was followed by the Chinese Civil War with the Communists taking over the city and most of the mainland. During the Cold War, trade was mostly limited to other socialist countries in the Eastern Bloc, causing the city's global influence to decline.

Chongqing is a direct-administered municipality in Southwestern China. Chongqing is one of the four direct-administered municipalities under the Central People's Government, along with Beijing, Shanghai, and Tianjin. It is the only direct-administered municipality located deep inland. The municipality covers a large geographical area roughly the size of Austria, which includes several disjunct urban areas in addition to Chongqing proper. Due to its classification, the municipality of Chongqing is the largest city proper in the world by population, though it is not the most populous urban area.

The municipality of Chongqing is the only Chinese city with a resident population of over 30 million; however, this number includes its large rural population. In 2020, Chongqing surpassed Shanghai as China's largest municipality by urban population; as of 2023, it had an urban population of 22.87 million. The municipality contains 26 districts, 8 counties, and 4 autonomous counties. The city served as the wartime capital for the Republic of China (ROC) during the Second Sino-Japanese War (1937–1945). On 14 March 1997, the current municipality was separated from the surrounding province of Sichuan, with the goal of furthering development in the central and western parts of the country.

Chengdu is the capital city of the Chinese province of Sichuan. With a population of 20,937,757 at the 2020 census, it is the fourth most populous city in China, and it is the only city with a population of over 20 million apart from provincial-level municipalities. It is traditionally the hub of Western China.

Chengdu is in central Sichuan. The surrounding Chengdu Plain is known as the "Country of Heaven" and the "Land of Abundance". Its prehistoric settlers included the Sanxingdui culture. The site of Dujiangyan, an ancient irrigation system, is designated as a World Heritage Site. The Jin River flows through the city. Chengdu's culture reflects that of its province, Sichuan; in 2011, it was recognized by UNESCO as a city of gastronomy. It is associated with the giant panda, a Chinese national symbol that inhabits the area of Sichuan; the city is home to the Chengdu Research Base of Giant Panda Breeding.

Tianjin is a major international port city in China. It is a direct-administered municipality on the shore of the Bohai Sea making it separate from the surrounding Hebei province. It is one of the nine national central cities, with a total population of 13,866,009 inhabitants at the time of the 2020 Chinese census. Its metropolitan area, which is made up of 12 central districts (other than Baodi, Jizhou, Jinghai and Ninghe), was home to 11,165,706 inhabitants in 2015 and is also the world's 29th-largest agglomeration (between Chengdu and Rio de Janeiro) and 11th-most populous city proper.

Tianjin is governed as one of the four municipalities (alongside Beijing, Shanghai, and Chongqing) under the direct administration of the State Council of China. However, it is the only municipality with a population of less than 20 million. The city borders Hebei Province and Beijing Municipality, bounded to the east by the Bohai Gulf portion of the Yellow Sea. Part of the Bohai Economic Rim, it is the largest coastal city in Northern China and part of the Jing-Jin-Ji megapolis.

Beijing is one of the four direct-administered municipalities of the People's Republic of China, and is divided into 16 districts.

The term district, in the context of China, is used to refer to several unrelated political divisions in both ancient and modern China.

In the modern context, district (区), formally city-governed district, city-controlled district, or municipal district (市辖区), are subdivisions of a municipality or a prefecture-level city. The rank of a district derives from the rank of its city. Districts of a municipality are prefecture-level; districts of a sub-provincial city are sub-prefecture-level; and districts of a prefecture-level city are county-level.
