Dafeng (simplified Chinese: 大丰; traditional Chinese: 大豐; pinyin: Dàfēng) is a coastal district under the administration of Yancheng, Jiangsu province, China. Located on the Jiangsu North Plain with a coastline of 112 km (70 mi), Dafeng was historically one of the largest salt-making areas in China and now is famed for its well preserved eco-system and numerous national conservation parks. The district has the largest national nature reserve for a rare deer species, Père David's Deer or Milu (麋鹿) in Chinese. It borders the prefecture-level city of Taizhou to the southwest.
The district nicknamed "the enclave of Shanghai" was a major destination for the sent-down youth from the city. Part of the county was put under Shanghai to establish a municipal farm since 1950, and there are still several farms and two prisons administered by Shanghai at present.
Zhang Jian established Ts'ao-yen-ch'ang Ta-feng Salt&Cultivation Limited Company (Chinese: 草堰場大豐鹽墾股份有限公司; pinyin: Cǎoyànchǎng Dàfēng Yánkěn Gǔfènyǒuxiàngōngsī) in 1917, at Caoyan, a town of Dafeng nowadays. The northern Dongtai under the CPC became a separate county in 1942. The county was designated Taipei (臺北) for its location (north [pei] of Dongtai [abbreviated to tai]). Considering its namesake in Taiwan, it was renamed Dafeng, derived from Zhang's company in 1951.
Dafeng borders four counties including Dongtai, Sheyang, Yancheng and Xinghua. The county has a coastline of 112 km (70 mi) and a magnificent size of the wetland along its coastline, which is around near 800,000 hectares, sheltering enormous numbers of species of insects, fish, wild animals, and millions of migrating birds.
Dafeng has a warm and wet subtropical climate and is influenced by the East Asian monsoon. It has distinct seasons and an abundant sunshine. The average annual temperature is close to 15 °C and the normal precipitation is over 1,000 mm yearly.
