The origin of Qingjiang Pujiang can be traced back to the Spring and Autumn Period. Fu Cha, the king of Wu, opened a ditch from Hancheng (now Yangzhou) to Wankou (now Huai 'an River Ancient Town) to transport grain for the war, connecting the Yangtze River and Huaihe River, and Huai 'an and Yangzhou began to rise. In the Sui Dynasty, Hangou became an important part of the Grand Canal, called Shanyangdu. The section of the Sui and Tang Canal from Sizhou (now Xuyi) to Yang Shan (now Huai 'an District) uses the natural Huaihe River, which makes navigation difficult and dangerous. The Yang Shan Bay section of this section of the river (in today's Huai 'an ancient Huaihe River section) is particularly turbulent due to the inflow of Surabaya, and it is even regarded as a dangerous road.
In the Song Dynasty, the transshipment in Huainan enabled Joe to dig a double-track canal-Shahe along the right bank of Huaihe River, connecting Mopankou (near Huaiyin Shiplock today) to Gumukou, so that ships could bypass the dangerous bay section. From the first year of Yongxi (984) to the seventh year of Yuanfeng (1084), the double-track canal was built in stages and opened to traffic one after another. From then on, "free from drowning." Shahe, the predecessor of Puhe River in Qingjiang River, played an important role in water transport in Song Dynasty, and gradually silted up after Yuan Dynasty.
It can be inferred from Li Zhi's masterpiece "Young Beauty, Jade Decline, Outside the Qingjiangpu" that the name of "Qingjiangpu" appeared in the Northern Song Dynasty. Documents such as Records of Emperor Taizong of Ming Dynasty, Records of Hequ in Ming Dynasty and Records of Caochuan can also prove that before Chen Xuan opened the port in the 13th year of Yongle in Ming Dynasty (14 15), "Qingjiangpu" had been named as the name of the old channel of Shahe River, and Qingjiangcao Shipyard had been built.
