What is the lowest temperature in Liaocheng in winter?

The coldest time is around minus 1, but now it's not so cold with the warming of the climate, so wander around minus 1 at the coldest time! I don't know exactly. Liaocheng belongs to that kind of dry and cold weather. You can spend the winter in a down jacket and wool pants, but some beautiful women also wear skirts. Hmm. How interesting
