Why Fushun is the coldest in Liaoning Province?

Fushun is surrounded by continuous mountains in the north, east and south, and borders Shenyang in the west, forming a "trumpet mouth" to the west. In winter, the cold northwest monsoon keeps blowing and pushing eastward. Topographically, Fushun is high in the east and low in the west, which is located at the end of Changbai Mountain. In winter, the cold air in high-altitude mountainous areas sinks from west to east along many east-west valleys, mainly along the Perilla River and Hunhe River (so Tonghua and Baishan are also very cold). In this way, the long-term confrontation between the east and west cold forces has been formed, and the situation of staying in Fushun has finally created the extremely cold weather in Fushun in winter! Of course, Dahuofang Reservoir also played a certain role!
