Why is it so hot in Beijing?

You shouldn't ask why Beijing is so cold in winter, should you?

But when I was in primary school, Beijing was not so hot at all.

From the fifth grade of primary school

A weather forecast said that Beijing reached 30 degrees, which made me feel bad. My mother said that when she was a child, the hottest temperature in Beijing was not even 30 degrees, and it was dry and hot, so as long as she was in a cool place, she would immediately cool down.

Beijing is quite comfortable these days. It's dry and hot at best. How do you feel when it's sultry in a few days? This is much better than the south.

Because Beijing is a big city with a large population, many cars and air conditioners. On the contrary, there are relatively few trees and relatively few water resources. This is called the urban heat island effect. As long as you go to the suburbs, the temperature will drop immediately. Obviously, my family lives outside the Fourth Ring Road, and there are no other residential areas around. The temperature is obviously cooler than the fourth ring road outside the three stations. The best thing is that it will cool off immediately after the Fourth Ring Road, because there are not many people on this side of the road.
