It is said that Kunming, Yunnan has four seasons like spring, but the temperature in Lijiang, Yunnan is below zero?

Kunming is a typical low latitude and high altitude area with high temperature at low latitude and low temperature at high altitude. The combination of latitude and altitude makes Kunming spring all the year round, but Zhaotong in the north of Yunnan never said it would snow, while Banna in the south is about 30 degrees. Lijiang is more than 500 kilometers away from Kunming, located in the northwest of Yunnan. Its altitude and latitude are much higher than those of Kunming (the temperature drops by 6 degrees every time the altitude rises 1000 meters). The temperature difference between day and night is large in winter, but there are few days below zero.
