During the spring and Autumn period and the Warring States period, Shanghai was the fief of Huang Xie, the king of Chunshen in the state of Chu. During the Jin Dynasty in the fourth and fifth centuries, because fishermen created fishing tools "Hu", the place where the river flowed into the sea was called "Du", so the lower reaches of Songjiang River was called "Hu Du" and later changed to "Hu", so Shanghai was called "Hu" for short.
