Shanghai, referred to as "Shanghai" or "Shen" for short, is the birthplace of China, a municipality directly under the Central Government of the People's Republic of China, a national central city, a megacity, a core city of Shanghai, Hangzhou and Ningbo, an international economic, financial, trade, shipping and scientific and technological innovation center, and the first batch of coastal open cities. Located at the mouth of the Yangtze River, Shanghai is the leading city in the Yangtze River Economic Belt, facing Kyushu Island across the sea, Hangzhou Bay in the south and Jiangsu and Zhejiang provinces in the northwest.

Shanghai is the fief of Huang Xie, the king of Chu's Spring Shen, so it is also called Shen. During the Jin Dynasty in the 4th and 5th centuries, because fishermen created a fishing tool "Hu", the place where the river flowed into the sea was called "blasphemy", so the downstream area of Songjiang was called "Hu" and later changed to "Shanghai", so Shanghai was called "Shanghai" for short. After 1843, Shanghai became an open commercial port and rapidly developed into the largest city in the Far East.
