Well, Beijing fun : 1. it usually exceeds 30(35 is common) degree C in day time. 2. There are too many people, so it increases the temperature farther in enclosed spaces. 3. Everyone and their dog have their air conditioner on full blast, therefore increases the heat (outside) even more.
Of course, I am crazy so I took in another business partner to shift and expand the thing, and I also took on some extra training courses. I get increased demand for business social events because I need to keep taps on my business contacts. And half the business meetings/training lessons requires me to look "nice", so I had to run around town in a long sleeved shirt, and a pair of steaming pants.
