"Anhui" in Chinese characters
|Literal meaning||"An[qing] and Hui[zhou cities]"|
Anhui ([ánxwéi]; Chinese: 安徽; pinyin: Ānhuī) is a landlocked province of the People's Republic of China located in the eastern region of the country. Located across the basins of the Yangtze River and the Huai River, it borders Jiangsu to the east, Zhejiang to the southeast, Jiangxi to the south, Hubei to the southwest, Henan to the northwest, and Shandong for a short section in the north. The provincial capital is Hefei.
The name "Anhui" derives from the names of two cities: Anqing and Huizhou (now Huangshan City). The abbreviation for Anhui is "Chinese: 皖; pinyin: wǎn" after the historical State of Wan, Mount Wan, and the Wan river.

The province of Anhui was formed in the 17th century. Before then, there was no coherent concept of "Anhui". In terms of culture, Northern Anhui was firmly a part of the North China Plain together with modern-day Henan province, northern Jiangsu and southern Shandong provinces. Central Anhui was densely populated and constituted mostly of fertile land from the Huai River watershed. In contrast, the culture of Southern Anhui, bordered mostly along the Yangtze, was closer to Jiangxi and southern Jiangsu provinces. The hills of southeastern Anhui formed a unique and distinct cultural sphere of its own.
In the 2007 book China Road, author Rob Gifford stated that the Chinese refer to Anhui as a "big agricultural province" (农业大省). According to Gifford, this is an euphemism for a "very poor" area and that people have referred to Anhui as the "Appalachia of China".
Anhui is quite diverse topographically. The north of the province is part of the North China Plain while the north-central areas are part of the Huai River watershed. Both of these regions are very flat and densely populated. The land becomes more uneven further south, with the Dabie Mountains occupying much of southwestern Anhui and a series of hills and ranges cutting through southeastern Anhui. The Yangtze River finds its way through south Anhui in between these two mountainous regions. The highest peak in Anhui is Lotus Peak, part of Huangshan in southeastern Anhui. It has an altitude of 1873 m.
Major rivers include the Huai River in the north and the Yangtze in the south. The largest lake is Lake Chaohu situated in the center of the province, with an area of about 800 km2 (310 sq mi). The southeastern part of the province near the Yangtze River has many lakes as well.
As with topography, the province differs in climate from north to south. The north is more temperate and has more clearcut seasons. January temperatures average at around -1 to 2 °C north of the Huai River, and 0 to 3 °C south of the Huai River; in July temperatures average 27 °C or above. Plum rains occur in June and July and may cause flooding.

The sixteen prefecture-level divisions of Anhui are subdivided into 105 county-level divisions (44 districts, 6 county-level cities, and 55 counties). Those are in turn divided into 1,845 township-level divisions (972 towns, 634 townships, nine ethnic townships, and 230 subdistricts).
The Politics of Anhui Province is structured in a dual party-government system like all other governing institutions in mainland China.
The Governor of Anhui (安徽省省长) is the highest-ranking official in the People's Government of Anhui. However, in the province's dual party-government governing system, the Governor has less power than the Anhui Communist Party of China Provincial Committee Secretary (安徽省委书记), colloquially termed the "Anhui Party Chief".
Agriculture in Anhui varies according to the climate zones that the province crosses. To the north of the Huai River, wheat and sweet potatoes are grown, while to the south of the Huai River it is rice and wheat instead.
Natural resources of Anhui include iron in Ma'anshan, coal in Huainan, and copper in Tongling. There are industries related to these natural resources (e.g. steel industry at Ma'anshan). One of the famous Anhui-based corporations is the automobile company Chery, which is based in Wuhu.
Compared to its more prosperous neighbours to the east, Zhejiang and Jiangsu, Anhui has lagged markedly behind in economic development, with a GDP per capita around one third the level of those two provinces. There is great regional disparity as well, and most of the wealth is concentrated in industrial regions close to the Yangtze River, such as Hefei, Wuhu, and Ma'anshan.
Anhui's nominal GDP for 2011 was approximately 1.51 trillion yuan (US$239.8 billion), up 12.9% from 2008 and a per capita of 16,391 yuan (US$2,400). It is considered a mid-size economy in terms of economic output. Anhui's GDP is largely driven by fixed-asset investment, and the province's GDP to FAI ratio as of 2009 was 0.89, the highest in China.
Anhui's largest companies include Anhui Conch Cement Company, a producer and distributor of cement, Guoyang Securities Co (SHE: 000728), a financial services provider, and Ma’anshan Iron & Steel, a producer of steel and iron.
Major Economic and Technological Development Zones
Hefei Economic and Technological Development Zone
Hefei Economic and Technological Development Zone is located in the southwest of Hefei. The zone is divided into two functional areas. The east part is allocated for manufacturing purpose and it also has two parks; the west part is where the business center, Hefei university town, and the international community center are located. It is established in 1993, and it is located close to Hefei Luogang International Airport.
Hefei Hi-Tech Industrial Development Zone
Hefei Hi-Tech Industrial Development Zone was founded in October 1990 and approved by the State Council as a state-level Development Zone in March 1991. In 1997, the Development Zone was ratified as an APEC Science and Technology Industrial Park, with special open policies to APEC and EU members. Hefei High Tech Park was also approved as a National High Tech Export Base in 2000 and obtained the award of an Advanced High Tech Zone under the Torch Program in 2003. So far, more than 100 hi-tech enterprises have entered the zone. Industries encouraged in the zone include Chemicals Production and Processing, Electronics Assembly & Manufacturing, Heavy Industry, Instruments & Industrial Equipment Production, Medical Equipment and Supplies, Research and Development, Telecommunications Equipment.
Wuhu Economic and Technological Development Zone
Established in 1993, Wuhu Economic & Technological Development Zone is the first state-level development zone approved by central government in Anhui Province. As the hub in the west of the Yangtze Delta, it is an ideal place for business in Central China and East China such as manufacturing place or logistic center due to great transportation advantage. Wuhu port is the last fine deepwater port here going against the Yangtse River. It is the main foreign trade base and overseas transportation center. It takes 1 hour from Wuhu to Nanjing Lukou International Airport and to Hefei Luogang Airport.
Wuhu Export Processing Zone

Historically, Anhui's transport network was hampered by the lack of bridges across the Yangtze River, which divides the province into northern and southern regions. The first bridge across the Yangtze in Anhui, the Tongling Yangtze River Bridge was completed in 1995. As of October 2014, Anhui had four bridges across the Yangtze, at Ma'anshan, Wuhu, Tongling, and Anqing.
Conventional railways in Anhui include the Beijing–Shanghai Railway, Beijing–Kowloon Railway, and Nanjing–Xi'an Railway that traverse the province north of the Yangtze River and the Nanjing−Tongling Railway, Anhui–Jiangxi Railway and Xuancheng–Hangzhou Railway that run south of the river.
Anhui has a highly unbalanced gender ratio. According to a 2009 study published in the British Medical Journal, in the 1-4 age group, there are 138 boys for every 100 girls, making it among the most unbalanced of provinces in China.
Anhui spans many geographical and cultural regions. The northern, flatter parts of the province, along the Huai River and further north, are most akin to neighbouring provinces like Henan, Shandong and northern Jiangsu. In contrast, the southern, hilly parts of the province are more similar in culture and dialect to other southern, hilly provinces, like Zhejiang and Jiangxi.
Mandarin dialects are spoken over the northern and central parts of the province, north of the Yangzi river. Dialects to the north (e.g. Bengbu dialect) are classified as Zhongyuan Mandarin, together with dialects in provinces such as Henan and Shandong; dialects in the central parts (e.g. Hefei dialect) are classified as Jianghuai Mandarin, together with dialects in the central parts of neighbouring Jiangsu province. Non-Mandarin dialects are spoken to the south of the Yangzi: dialects of Wu are spoken in Xuancheng prefecture-level city, though these are rapidly being replaced by Jianghuai Mandarin; dialects of Gan are spoken in a few counties in the southwest bordering Jiangxi province; and the Huizhou dialects are spoken in about ten counties in the far south, a small but highly diverse and unique group of Chinese dialects.
Huangmeixi, which originated in the environs of Anqing in southwestern Anhui, is a form of traditional Chinese opera popular across China. Huiju, a form of traditional opera originating in the Huizhou-speaking areas of southern Anhui, is one of the major precursors of Beijing Opera; in the 1950s, Huiju (which had disappeared) was revived. Luju is a type of traditional opera found across central Anhui, from east to west.
Anhui cuisine is one of the eight great traditions of Chinese cuisine. Combining elements of cooking from northern Anhui, south-central Anhui, and the Huizhou-speaking areas of southern Anhui, Anhui cuisine is known for its use of wild game and herbs, both land and sea, and comparatively simple methods of preparation.
Anhui has a high concentration of traditional products related to calligraphy: Xuanzhou (today Xuancheng) and Huizhou (today Huangshan City) are revered for producing Xuan Paper and Hui Ink, respectively, which are traditionally considered the best types of paper and ink for Chinese calligraphy. She County is famous for the She Inkstone, one of the most preferred types of inkstones (a required tool in traditional calligraphy).
The predominant religions in Anhui are Chinese folk religions, Taoist traditions and Chinese Buddhism. According to surveys conducted in 2007 and 2009, 4.64% of the population believes and is involved in ancestor veneration, while 5.30% of the population identifies as Christian. According to a 2010 survey, Muslims constitute 0.58% of the population of Anhui .
The reports didn't give figures for other types of religion; 89.48% of the population may be either irreligious or involved in worship of nature deities, Buddhism, Confucianism, Taoism and folk religious sects.

- The data was collected by the Chinese General Social Survey (CGSS) of 2009 and by the Chinese Spiritual Life Survey (CSLS) of 2007, reported and assembled by Xiuhua Wang (2015) in order to confront the proportion of people identifying with two similar social structures: ① Christian churches, and ② the traditional Chinese religion of the lineage (i. e. people believing and worshipping ancestral deities often organised into lineage "churches" and ancestral shrines). Data for other religions with a significant presence in China (deity cults, Buddhism, Taoism, folk religious sects, Islam, et. al.) was not reported by Wang. The number of Muslims is taken from a survey reported in the year 2010.
