@gemlog I live in Beijing. Usually, it shouldn't be that hot and humid. But in recent years it has got hotter and hotter.

I heard that in Shanghai or Guangzhou, the apparent temperature reached even 50+ C, and above 40+ C most time. One of my friends said they had 100% humidity in Hainan several days ago.

Anyway, I have a coaster that uses some fancy refrigeration tech, which outputs heat but generates cold. So, having some (nearly) ice-cold tea will help a lot. The only problem is that, with this high humidity, there is a lot of condensation XD
