Lhasa and Kunming have no air conditioning.

What you want to ask is why there are no air conditioners in Lhasa and Kunming. The reason for this is the following：

1, Lhasa: Lhasa is located on the Qinghai-Tibet Plateau, with a cold and dry climate, high temperature in summer and low relative humidity. Because the climate is dry, there is no need to use air conditioning to reduce the indoor temperature. In addition, Lhasa is located in a high-altitude area, and the temperature is lower than that of low-altitude cities such as Kunming, so there is less demand for air conditioning.

2. Kunming: Kunming is located in Yunnan Province, with a subtropical plateau climate and warm and humid summer. Because Kunming is humid in summer, people will feel sultry, but the relative temperature is low. We can reduce the indoor temperature by ventilation and so on, and don't rely too much on air conditioning.
