Do you know when the coldest weather in Hainan's history is? Thank you.

. . . . Upstairs. 2005 is also called cold!

The coldest is the winter of 1999. . It's 3 degrees in central Hainan. . You can see the frost on the tree when you get up in the morning!

It was only 5 6 degrees in the north that year. That year was the first time I heard about Hainan, because it was cold. And take a holiday in advance!
