In 75 1 year (the tenth year of Tang Tianbao), Shanghai belonged to Huating County (now Songjiang District), covering Hongkou in the north, the seaside in the south and Xiasha in the east. In 99 1 year (the second year of Song Chunhua), due to the continuous shallow siltation in the upper reaches of Songjiang, the coastline moved eastward, and it was inconvenient for large ships to enter and leave, so foreign ships had to dock at "Shanghai Pu", a tributary of Songjiang (located on the Huangpu River near Dongshiliupu of the Bund today). In A.D. 1267 (the third year of Xianchun in the Southern Song Dynasty), a town was set up in Puxi, Shanghai, named Shanghai Town. In A.D. 1292 (twenty-nine years from Yuan Dynasty to Yuan Dynasty), the central government of Yuan Dynasty drew Shanghai out of Huating County and approved the establishment of Shanghai County, marking the beginning of Shanghai's construction.
