Why is the weather in Kunming so good?

Because Dianchi Lake has helped a lot.

Dianchi Lake is like a big air conditioner.

Because water dissipates heat and absorbs heat more slowly than the ground.

So it absorbs heat when it is hot and dissipates heat when it is cold.

In addition, the geographical locations of Dianchi Lake and Kunming City are just right.

Therefore, Kunming is the only city in the world that is neither too cold in winter nor too hot in summer.
