What's the temperature in Liupanshui? How long is winter?

Liupanshui is generally not cold, and the temperature is between minus 5 degrees and 10 degrees, but it is rarely below zero, which is estimated to be one year 10 days. But Liupanshui is very uncomfortable in winter, because it always rains in winter in Mao Mao, and Liupanshui is a heavy industrial city, and the ground in the urban area is covered with mud and black mud, that is, coal ash. Also very annoying.
