How is the weather in Tongmuguan, Wuyishan? How is the weather in Guangzhou?

I can tell you about Guangzhou, because I’m nearby. It’s still very hot right now, with a maximum of 30 or 31 degrees, but it gets cooler in the morning and evening, so you don’t need to turn on the air conditioner. It's been like this for the past week. I guess it hasn't changed much when you came here. The clothes are still mainly short-sleeved. You can bring a long-sleeved thin jacket for use at night or when you go to a place with high air conditioning.
