What clothes should I take to travel to Kunming in July? How's the weather?

The annual average temperature in Kunming is about 15 degrees, the hottest month is between 19-22 degrees, and the highest temperature does not exceed 3 1.5 degrees. It's still hot there during the day, so remember to bring more summer clothes, but it's usually cold at night, so it's best to bring a thin coat (long sleeves) and a pair of pants, because it's in the precipitation period (5-0.5 degrees every year). ..
