What should I do if the weather is too hot in Shenzhen?

You can directly choose to go to KFC, McDonald's, Wallace and other popular restaurants (the kind that doesn't order food) to rub the air conditioner for free. Or find a hotel and rub the air conditioner in the hotel lobby for free. Or directly bring a mobile phone charger into milk tea, while charging, pull out WIFI and rub the air conditioner. Kill two birds with one stone! No one will kick you out, you can stay there all day! ! At the waiter's place, visitors are guests! So hot weather is ok.
