Does air conditioning need to be turned on in Nanning, Guangxi in winter?

Need

I like the winter in Nanning the most. It’s so beautiful when I don’t have to wear thick and round clothes. I used to be most afraid of winter. I am most afraid of the cold. I feel cold even if I don’t go out and turn on the air conditioner and heater. Ever since I came to Nanning, the winter has been so beautiful. When it’s the coldest, you can just wear a coat. It’s the same at night. You can also wear a nice skirt and you’re not afraid of the cold. It’s coldest at night. Only about ten degrees
