According to the local treasure of Yichang, the address of Mao Ping Wharf is about 1 10 meters east of Ziguigang Bus Terminal, Binhu Avenue, Zigui County, Yichang City. Mao Ping Port is located on the south bank of the upstream axis of the Yangtze River Dam, about 3 kilometers away, echoing the upstream Chongqing Port. It is a veritable "No.1 Port in the dam head" in the Three Gorges reservoir area. Due to the restrictions of the double-track five-level shiplock and Gezhouba of the Three Gorges Dam, ships in the reservoir area are relatively blocked from crossing the dam. In order to shorten the navigation time of crossing the dam by six or seven hours, ships crossing the dam have chosen to turn over the dam here for transshipment. It has the special status of "hub port, transit port, origin port and destination port" in the Three Gorges reservoir area.
