Introduction to water transportation: Since the establishment of the Wei Dynasty in the Ming Dynasty, Tianjin has developed rapidly with the help of water and sea transportation. "Nine rivers flow down the Tianjin Wei, and seventy-two sails make the shadow far away" is a true portrayal of Tianjin Wei at that time. Xianshuigu, one of the seventy-two Gu, relies on the Haihe River. It has been a river port since the Ming Dynasty and was still dominant in the late Qing Dynasty and the Republic of China. The name of Xianshuigu today probably comes from the Qing Dynasty.
