"Shanghai" literally means the “City on the Sea.” Specifically, Shanghai is located at the entrance of the Yangtze River to East China Sea. The city is built on an alluvial plain with an average elevation of 4 meters. The Suzhou River comes from the west, and the Huangpu River crosses the city. The west bank of the river is called Puxi, and the east bank of the river is called Pudong. Teaching in Shanghai is a good choice.
