Why is Hami in Xinjiang particularly hot in summer and Qujing in Yunnan particularly cold?

So many people's comments are irrelevant and don't understand geographical common sense. Speaking of latitude, the latitude in Xinjiang is higher than that in Qujing, Yunnan, and it should be colder, but the temperature is not only determined by latitude, but also related to altitude. The altitude of Qujing in Yunnan is 1.890 meters, and that of Turpan in Xinjiang is-1.500 meters. Generally, the temperature drops by 6 degrees every time the altitude rises 1000 meters. Our Qujing is generally not more than 30 degrees in summer, and residents have no air conditioning at home. In addition, Yunnan has good precipitation conditions and high vegetation coverage. It is one of the few cities in China without air conditioning (if the whole country is the same, Dong Mingzhu can't do Gree air conditioning). It is also one of the Spring Cities, but it is not as famous as Kunming. Welcome to our Qujing for the summer vacation!
