There are two tributaries on the south bank of Suzhou River, one is called Shanghai Pu and the other is called Shanghai Pu. The town is located near Shanghai Pu, hence the name Shanghai Town. This is the origin of Shanghai place names. In the twenty-ninth year of Yuan Shizu to Yuan Dynasty, namely 1292, Shanghai County was established. 1927 changed to Shanghai Special City. 1949 after the establishment of People's Republic of China (PRC), it was changed to a municipality directly under the central government.
