When is the coldest time in Yinchuan?

It's MINUS 20 degrees, and the average temperature in winter is about MINUS 15 degrees. If it snows, the average thickness is around 10mm, but it hasn't snowed much in recent years. Because the northwest wind blows more, you must prepare down jackets or coats, cotton scarves and cotton shoes are all necessary. If you are a man, it is recommended to bring at least two pairs of cotton trousers or one pair of down trousers.
