Is it cold in winter in Xi? Is it hot again in summer? The air is a little dry?

In fact, it's not very cold in winter, but in summer, Gesien is definitely that kind of sun exposure, that is, dry heat. Let me give you an example. Last year, Xi 'an City Express threw an egg on a concrete table at noon in mid-July and it solidified for more than 40 minutes. Forget it, the ground temperature in Xi 'an can reach 50 in summer. . . . Hot (the best thing is that the weather forecast says the highest temperature is 38 degrees (# ‵'))
