Hefei
Hefei (; ) is the capital and largest city of Anhui Province, People's Republic of China. A prefecture-level city, it is the political, economic, and cultural center of Anhui. Its population was 9,369,881 as of the 2020 census and its built-up (or metro) area made up of four urban districts plus Feidong, Feixi and Changfeng counties being urbanized, was home to 7,754,481 inhabitants. Located in the central portion of the province, it borders Huainan to the north, Chuzhou to the northeast, Wuhu to the southeast, Tongling to the south, Anqing to the southwest and Lu'an to the west. A natural hub of communications, Hefei is situated to the north of Chao Lake and stands on a low saddle crossing the northeastern extension of the Dabie Mountains, which forms the divide between the Huai and Yangtze rivers.

The present-day city dates from the Song dynasty. Before World War II, Hefei remained essentially an administrative centre and the regional market for the fertile plain to the south. It has gone through a growth in infrastructure in recent years. Hefei is the location of Experimental Advanced Superconducting Tokamak, an experimental superconducting tokamak magnetic fusion energy reactor.

Hefei is a world leading city for scientific research, with its ranking placed at 16th globally, 8th in the Asia-Pacific and 6th in China (behind Beijing, Shanghai, Nanjing, Guangzhou and Wuhan), as tracked by the Nature Index in 2022. The city is represented by several major universities, including the University of Science and Technology of China, Hefei University of Technology, Anhui University, Anhui Agricultural University and Anhui Medical University. Notably, the University of Science and Technology of China is one of the top 100th comprehensive public research universities in the world.

History

From the 8th to the 6th centuries BC, Hefei was the site of many small states, later a part of the Chu kingdom. Many archaeological finds dating from this period have been made. The name 'Hefei' was first given to the county set up in the area under the Han dynasty in the 2nd century BC.

In the 3rd century AD, the Battle of Xiaoyao Ford was fought at Xiaoyao Ford () in Hefei. Zhang Liao, a general of the Wei state, led 800 picked cavalry to defeat the 200,000-strong army from Wei's rival state Wu. Several decades of warring in Hefei between Wu and Wei followed this battle.

During the 4th to the 6th centuries AD, this crucial border region between northern and southern states was much fought over; its name and administrative status were consequently often changed. During the Sui (581–618) and Tang (618–907) periods, it became the seat of Lu prefecture—a title it kept until the 15th century, when it became a superior prefecture named Luzhou.

The present city dates from the Song dynasty (960–1126), the earlier Hefei having been some distance farther north. In the 10th year of Xining (, 1077 AD), the taxes collected from the Luchow Prefecture were 50315 Guan, approximately 25 million today's Chinese Yuan, with a ranking of the amount of taxes was the 11th(following Kaifeng, Hangzhou, Qinzhou, Chuzhou, Chengdu, Zizhou, Xingyuan, Mianzhou, Zhenzhou, Suzhou) among all the prefectures of Song Dynasty. During the 10th century, it was for a while the capital of the independent Wu kingdom (902–938) and was an important center of the Southern Tang state (937–975).

After 1127 it became a center of the defenses of the Southern Song dynasty (1126–1279) against the Jin (Jurchen) invaders in the Jin–Song wars, as well as a flourishing center of trade between the two states. When the Chinese Republic was founded in 1911, the superior prefecture was abolished, and the city took the name of Hefei. The city was known as Luchow or Liu-tcheou (, p Luzhou) during the Ming and Qing dynasties (after the 14th century to the 19th century). Hefei was the temporary capital for Anhui from 1853 to 1862. It was renamed as Hefei County in 1912. Following the Chinese victory in the Second Sino-Japanese War in 1945, Hefei was made the capital of Anhui.

Before World War II, Hefei remained essentially an administrative center and the regional market for the fertile plain to the south. It was a collecting center for grain, beans, cotton, and hemp, as well as a center for handicraft industries manufacturing cloth, leather, bamboo goods, and ironware.

The construction in 1912 of the Tianjin–Pukou railway, farther east, for a while made Hefei a provincial backwater, and much of its importance passed to Bengbu. In 1932–36, however, a Chinese company built a railway linking Hefei with Yuxikou (on the Yangtze opposite Wuhu) to the southeast and with the Huai River at Huainan to the north. While this railway was built primarily to exploit the rich coalfield in northern Anhui, it also did much to revive the economy of the Hefei area by taking much of its produce to Wuhu and Nanjing.

Although Hefei was a quiet market town of only about 30,000 in the mid-1930s, its population grew more than tenfold in the following 20 years. The city's administrative role was strengthened by the transfer of the provincial government from Anqing in 1945, but much of its new growth derived from its development as an industrial city. A cotton mill was opened in 1958, and a thermal generating plant, using coal from Huainan, was established in the early 1950s. It also became the seat of an industry producing industrial chemicals and chemical fertilizers. In the late 1950s an iron and steel complex was built. In addition to a machine-tool works and engineering and agricultural machinery factories, the city has developed an aluminum industry and a variety of light industries. Hefei's development was advanced by the Third Front construction. It has since developed high-tech industries, including those involving semi-conductors and alternative energy.

There are several universities based in the city. These include the University of Science and Technology of China, which is one of the best technological universities in the country.

Geography

Hefei is located  west of Nanjing in south-central Anhui. Chao Lake, a lake  southeast of the city, is one of the largest fresh water lakes in China. Though, the lake has unfortunately been polluted with nitrogen and phosphorus, in recent decades, the situation is improving due to efforts by both the government and the people.

Climate
Hefei features a humid subtropical climate (Köppen Cfa) with four distinct seasons. Hefei's annual average temperature is . Its annual precipitation is just slightly over , being heavier from May through August. Winters are damp and cold, with January lows dipping just below freezing and January averaging . The city sees irregular snowfalls that rarely turn significant .Springs are generally relatively pleasant if somewhat erratic. Summers here are oppressively hot and humid, with a July average of . In the months of June, July, August, and often September, daily temperatures can reach or surpass  with high humidity levels being the norm. Autumn in Hefei sees a gradual cooling and drying. With monthly percent possible sunshine ranging from 35 percent in March to 50 percent in August, the city receives 1,868 hours of bright sunshine annually. Extremes since 1951 have ranged from  on 6 January 1955, to  on 27 July 2017.

Air pollution

Air quality typically diminishes in May and June when the city is blanketed by smog caused by the smoke generated as farmers outside the city burn their fields in preparation for planting the next crop.

Administrative divisions and demographics

Demographics
The majority of the population in Hefei are Han Chinese.  There are a comparatively small number of Hui Chinese living in the city, for whom a few mosques have been constructed.  Of the more than five million people in the city, some are migrant workers from other parts of Anhui.

Administration
The prefecture-level city of Hefei administers 9 county-level divisions, including 4 districts, 1 County-city and 4 counties.

Hefei subdivisions area (km2), population (According to 2010 Census) and population density (per km2).

Economy

As of 2021, the GDP of Hefei is ¥1,141.28 billion. The GDP per capita of the city is ¥121,187 (US$18,784), ranking within the top 20 of cities in China.

Before the Chinese Civil War, Hefei's main industry was agriculture. After World War II, the capital of Anhui was moved from Anqing to Hefei. To assist the development of the city, many talented people were sent in from other parts of the country. Modern-day Hefei has machinery, electronics, chemistry, steel, textile, and cigarette industries, among others.

In 2008, the local government spent US$3.5 billion for a controlling ownership stake in BOE Technology (Jingdongfang). BOE Technology subsequently grew to be one of the world's leading manufacturers of semiconductor products for telecommunications. 

Hefei 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, Ma'anshan, Pingdingshan and Shenyang), an economic profile of the top 20 emerging cities in China.

Hefei was identified by The Economist in December 2012 as the world's No.1 fastest growing metropolitan economy.

The local government invested heavily in NIO in order to integrate it with Hefei Changan Automobile, a legacy enterprise from the Third Front construction. NIO was on the brink of bankruptcy in 2020 when Hefei obtained a 25% stake in the company in exchange for RMB 7 billion. NIO moved its headquarters to Hefei, where the government helped it obtain loans from local banks to expand its supply chains. As of 2022, NIO is China's most successful electric vehicle manufacturer.

Transportation
Hefei has been the provincial capital since 1945 (before it was Lihuang, which is today's Jinzhai) and is a natural center of transportation, being situated to the north of Chao Lake and standing on a low saddle crossing the northeastern extension of the Dabie Mountains, which form the divide between the Huai and Yangtze rivers. From Hefei there is easy water transport via the lake to the Yangtze River opposite Wuhu.

Rail
There are two main train stations in Hefei. The newest one is Hefei South railway station (Hefeinan station, 合肥火车南站) where most high-speed trains pass through. Many city buses serve this station, for instance the 108 from the East gate of the University of Science and Technology's East campus on Susong road. It has a very comprehensive taxi rank with multiple queues to avoid a long wait. There are many fast food restaurants in the departure hall with seating. There are not so many options for arrivals, a small cafe and a takeaway kfc booth. There is an ATM in the ticket sales area next to the security gates for the departure hall.

The alternative station is Hefei railway station () which is smaller and older. This has only one taxi queue, directly opposite the main exit. There is fast food, a post office and a China mobile store in the same courtyard next to the arrival gates.

There are some small stations such as Feidong Station (), Feixi Station (), Shuijiahu Station (), Chaohu Station (), Chaohu East railway station (Chaohudong station; 巢湖火车东站), Hefeibeicheng Station (Hefei Northtown Station 合肥北城火车站), Lujiang Station () and so on. These stations are mostly located in small towns or played commuting roles.
