The weather in Yichun in winter

The coldest time in Yichun is around 3 degrees below zero, rarely below zero, and more around zero. But winter in Yichun is not suitable for people. There is a lot of rain in winter, and it is always mixed with moisture when it is cold, and this biting feeling is that it has been sticking to you and it is cold everywhere. We only turn on the air conditioner in winter here, and there is always a feeling of warm body and cold feet. Unlike the heating in the north, everyone is warm, and we don't like to use floor heating for decoration here. How can it be a cold word?
