The geographical environment of Yancheng

Yancheng's climate belongs to the transitional zone between the tropical climate in North Asia and the warm temperate climate in South China. Generally, it is bounded by the main irrigation canal, with the north subtropical climate zone in the south and the south warm temperate climate zone in the north.
