What clothes should I take to Deqin in mid-March, and what is the road condition?

A jacket with wool is enough. I went to the Spring Festival this year, and it was as hot as Kunming! And remember to bring some short-sleeved clothes that can be changed after sweating. Of course, you should inquire about the weather before you leave. If it snows suddenly, of course, it is another matter. The scenery of the rain collapse in March is average. It might be better if you go in April!
