Is it very cold in Xi 'an in winter? It's hot again in summer? And the air is a little dry?

In fact, it is not very cold in winter, but in summer, Gessien is definitely the kind of sun-exposed heat, that is, dry heat. Let me give you an example. Last year, Xi 'an City Express gave an egg to the cement table at noon in mid-July, and it solidified for more than forty minutes. Forget it, the ground temperature in Xi 'an in summer can reach 5. . . . Hot (the most awesome thing is that the weather forecast said that the highest temperature was 38 degrees (# ‵'))
