Can Tomb-Sweeping Day wear short sleeves in Guiyang?

No, it's raining in Mao Mao in Guiyang these days. As the saying goes: "It rains like winter in Guiyang." Moreover, the recent weather in Guiyang is very unstable, sometimes it is super hot and sometimes it is super cold.

I don't think it will be hot in Tomb-Sweeping Day these days. You'd better wear a T-shirt and a coat, which is better!

As for Tomb-Sweeping Day, it's hard to say. You'd better dress according to the weather in those days. It's hard to say when the weather is good and when it's not. At present, the weather in Guiyang is difficult for meteorologists to tell!
