Why can't Beijing feel so hot in summer?

I still feel quite hot, but it is the hottest time at noon. Although I can't say that I will get heatstroke, there may be a girl with a little hypoglycemia on the subway a few days ago. Besides, it was sultry, so she fainted. It took a long time to recover. At the moment when the gate was brushed at the exit, a girl fell to the ground directly. A staff member keeps asking if he can get up, which is a matter of time, so whether it is hypoglycemia or physical discomfort, he should pay more attention when going out in hot weather, especially in dog days. While paying attention to heatstroke prevention and cooling, we should also pay more attention to our health. After all, your health is the capital of the revolution.
