What's the weather like in Tongmuguan, Wuyishan? What is the weather like in Guangzhou?

I can tell you in Guangzhou, because I am nearby, and it is still very hot, the highest is 30 or 3 1 degree, but it is already cold in the morning and evening, so there is no need to turn on the air conditioner. It's been like this for the last week. I guess nothing has changed since I came. You should still wear short sleeves if you are dressed. You can take a thin coat with long sleeves and use it at night or in a place with large air conditioning.
