# Beichen, Tianjin

Beichen District (simplified Chinese: 北辰区; traditional Chinese: 北辰區; pinyin: Běichén Qū) is a district of the municipality of Tianjin, People's Republic of China. Before June 1992, the district was named Beijiao District (simplified Chinese: 北郊区; traditional Chinese: 北郊區; pinyin: Běijiāo Qū; lit. 'north suburb'), reflecting its position in the northern suburbs of Tianjin. As the city expanded, it gradually became part of the urban core and was renamed to Beichen.
The district occupies approximately 478.5 km$^2$ (184.7 sq mi), with a population of 320,000. China National Highway 103 goes through the heart of the district. Beichen District also hosts the North Canal (北运河), a branch of the Hai River.
