Shanghai in the context of "Chongming District"

China, officially the People's Republic of China (PRC), is a country in East Asia. With a population exceeding 1.4 billion, it is the second-most populous country after India, representing 17% of the world population. China borders fourteen countries by land across an area of 9.6 million square kilometers (3,700,000 sq mi), making it the third-largest country by area. The country is divided into 33 province-level divisions: 22 provinces, 5 autonomous regions, 4 municipalities, and 2 semi-autonomous special administrative regions. Beijing is the capital, while Shanghai is the most populous city by urban area and largest financial center.

China saw the first humans in the region arriving during the Paleolithic era. By the 2nd millennium BCE dynastic states had emerged in the Yellow River basin. The 8th–3rd centuries BCE saw a breakdown in the authority of the Zhou dynasty, accompanied by the emergence of administrative and military techniques, literature and philosophy. In 221 BCE, China was unified under an emperor, ushering in two millennia of imperial dynasties. With the invention of gunpowder and paper, the establishment of the Silk Road, and the Great Wall, Chinese culture flourished and has heavily influenced its neighbors and lands further afield. China began to cede parts of the country in the 19th century, to European powers by a series of unequal treaties. The 1911 Revolution overthrew the Qing dynasty and the Republic of China was established the following year. The country was unstable and fragmented during the Warlord Era, which ended upon the Northern Expedition conducted by the Kuomintang to reunify the country.

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.

Qidong is a county-level city under the administration of the prefecture-level city of Nantong in southeastern Jiangsu province, China. It is located on the north side of the Yangtze River opposite Shanghai and forms a peninsula jutting out into the East China Sea. It has a population of 967,313 in 2020.

The center of the city is named Huilong Township. It also has a well-known fishing port called Lüsi town, named after Lü Dongbin, one of the eight immortals, who is said to have visited the place four times. Qidong's Qilong township was formerly a separate island in the Yangtze called Yonglongsha but now forms a pene-enclave on Chongming Island, most of which belongs to Shanghai.

A direct-administered municipality (直辖市; Zhíxiáshì; lit. 'direct-administered city'), commonly known as municipality, is a provincial-level administrative division in China. The municipalities are directly affiliated to the central government of China. Although a city by name, a Chinese municipality is more than a city in a traditional sense. It is equivalent to a province as it usually composed of a central urban area and a number of much larger surrounding suburban and rural areas. There are four such municipalities in China: Beijing, Chongqing, Shanghai, and Tianjin.

Beijing, previously romanized as Peking, is the capital city of China. With more than 22 million residents, it is the world's most populous national capital city, as well as China's second largest city by urban area, after Shanghai. It is located in Northern China, and is governed as a municipality under the direct administration of the State Council with 16 urban, suburban, and rural districts. Beijing is mostly surrounded by Hebei Province and neighbors Tianjin to the southeast; together, the three divisions form the Jing-Jin-Ji cluster.

Beijing is a global city and one of the world's leading centres for culture, diplomacy, politics, finance, business and economics, education, research, language, tourism, media, sport, science and technology, transportation, and art. It is home to the headquarters of most of China's largest state-owned companies and houses the largest number of Fortune Global 500 companies in the world, as well as the world's four biggest financial institutions by total assets. It is also a major hub for the national highway, expressway, railway, and high-speed rail networks. For a decade before the COVID-19 pandemic, Beijing Capital International Airport was Asia's busiest airport (2009–2019) and the second busiest airport in the world (2010–2019). In 2020, the Beijing subway was the fourth busiest and second longest in the world. Beijing Daxing International Airport, Beijing's second international airport, is the largest single-structure airport terminal in the world. The city has hosted numerous international and national sporting events, the most notable being the 2008 Summer Olympics and 2008 Summer Paralympics Games. In 2022, Beijing became the first city ever to host both the Summer and Winter Olympics, and also the Summer and Winter Paralympics.

As of 2023, the five largest cities in China by population are Chongqing (31.91 million), Shanghai (24.87 million), Beijing (21.86 million), Chengdu (21.403 million) and Guangzhou (18.827 million). As of 2024, there are 18 megacities (cities with a population of over 10 million), including Chongqing, Shanghai, Beijing, Chengdu, Guangzhou, Shenzhen, Wuhan, Tianjin, Xi'an, Suzhou, Zhengzhou, Hangzhou, Shijiazhuang, Linyi, Dongguan, Qingdao, Changsha and Hefei.

Among them, the total permanent population of Chongqing, Shanghai, Beijing and Chengdu is above 20 million. Shanghai is China's most populous urban area, while Chongqing is its largest city proper, the only city in China with the largest permanent population of over 30 million.

Jiangsu is a coastal province in East China. It is one of the leading provinces in finance, education, technology, and tourism, with its capital in Nanjing. Jiangsu is the third smallest, but the fourth most populous, with a population of 84.75 million, and the most densely populated of the 22 provinces of the People's Republic of China. Jiangsu has the highest GDP per capita and second-highest GDP of Chinese provinces, after Guangdong. Jiangsu borders Shandong in the north, Anhui to the west, and Zhejiang and Shanghai to the south. Jiangsu has a coastline of over 1,000 kilometers (620 mi) along the Yellow Sea, and the Yangtze flows through the southern part of the province.

Since the Sui and Tang dynasties, Jiangsu has been a national economic and commercial center, partly due to the construction of the Grand Canal. Cities such as Nanjing, Suzhou, Wuxi, Changzhou, and Shanghai (separated from Jiangsu in 1927) are all major Chinese economic hubs. Since the initiation of economic reforms in 1990, Jiangsu has become a focal point for economic development. It is widely regarded as one of China's most developed provinces, when measured by its Human Development Index (HDI). Its 2021 nominal GDP per capita reached CN¥137,300 (US$21,287), becoming the first province in China to reach the $20,000 mark.

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.

The Port of Shanghai (Chinese: 上海港; pinyin: Shànghǎi Gǎng ; Wu; Zånhae Kån) is located in the vicinity of Shanghai. It comprises a deep-sea port and a river port.

The main port enterprise in Shanghai, the Shanghai International Port Group (SIPG), was established during the reconstitution of the Shanghai Port Authority. Companies such as the Shanghai Port Container Co. and Waigaoqiao Bonded Zone Port Co. were involved.
