Weather conditions in Tibet and Chengdu

You don't have to worry about Chengdu. The climate is very good, and the heat and cold are similar to those in southern cities.

As for Tibet, I can only say that the weather in Lhasa is very different in the morning and evening. Now the sun is a little hot during the day, so just wear a thin cotton-padded coat. It may be a little cold in the morning and evening, so wear a thicker cotton-padded coat.

As for you going to Naqu Ali, you need a down jacket.

It is best not to catch a cold when coming to Tibet, which will cause pulmonary edema.

Take more rest in the first few days after coming, and you can take some altitude medicine, as long as there is no heart disease, the problem is not big and it is not so scary.

As for the danger you mentioned, don't worry, Tibet is very peaceful now, and soldiers don't eat for nothing.
