Zhangping (ancient Zhangzhou capital Zhangping County, Ningyang County) is located in the southwest of Fujian Province, in the upper reaches of the Jiulong River (Beixi), between 24 °54 miles north latitude and 117 °11 miles east longitude. It is located in the east gate of western Fujian, Yongchun and Anxi in the east, Hua'an and Nanjing in the south, Silla in the west, Yongan and Datian in the north, Xiamen and other developed coastal areas in southern Fujian. It connects the hinterland of Fujian, Guangdong and Jiangxi. Zhangping bought the county in the seventh year of Chenghua in the Ming Dynasty (1471), and withdrew the county to build the city in 1990. Zhangzhou Qiang Zhangping dialect is popular in Minnan dialect (some areas such as Xinqiao in Xinan are close to Quanzhou as spring cavities). In 2017, the regional GDP reached 23.256 billion yuan, an increase of 8% over the previous year.
