What should I prepare for going to Shangri-La at the end of March?

Shangri-la needs to be prepared. It's slightly cold in March. Be sure to bring warm clothes such as cotton-padded clothes and down jackets, and keep warm. Ultraviolet rays at high altitudes are extremely strong. It is recommended to bring sunscreen products. There may be altitude sickness. Take Oumailan tablets, American ginseng and glucose solution to prevent altitude sickness.
