How does the weather in Xi 'an compare with that in April and May in Fujian?

Haha, I am a student in Fujian, studying in Xi 'an .. dryness is inevitable, unlike the hot and humid weather in Xiamen. Xi is dry and hot, but if you come to travel for a week, it's absolutely no problem. The temperature on May Day is usually 18-28 degrees, but you can't say for sure, because it snowed in Xi 'an yesterday, and the weather forecast says that the temperature will reach 20 degrees tomorrow ... radiation is generally accepted.
