Should I wear sunglasses when going to Lijiang in February?

You'd better wear sunglasses and sunscreen. We have lived in Yunnan for a long time, so it is better to wear a hat, because the ultraviolet rays here are strong and it is easy to get tanned. There is air conditioning, see if you are in the northeast, because it is not too cold in winter and the wind is a bit strong. If you are used to heating in the northeast, you should choose air conditioning. If you are in the south, it is not necessary. General inns will have electric blankets. You can ask the store before booking, generally.
