Wow, you do make a good choice to stay in Kunming because the weather of Kunming is very pleasant and comfortable. In most days all the year round, it could be like the early spring. The annual average temeprature is about 15-16 C, and even in the hottest days, the temperature wio't reach to 30 C. So you can take along long-sleeved shirt and light coat with you. Of course, you can also take some thick overcoat in case of the sudden coldness. By the way, the rainy season of Kunming is from May to October, so you should prepare the rainy wear or umbrella as well.
Of course, the visa and the passport are necessary.Besides, you can just take something you use for daily life because you can buy other things in Kunming.
