Chongqing CHAO TIAN MEN is located in northeast of Yuzhong District, where the Yangtze river and Jialing river meet. The site is surrounded by water on three sides, and the terrain is medium and high. Although it has been transformed, there are long and steep stone stairs connecting the river-side wharf. At the beginning of the Ming dynasty, the city gate was built here. Due to the facing direction is sacred capital Nanking, it got the name of CHAO TIAN MEN, which means facing the empire.
