What clothes do you need to wear in cold weather in Haikou? Sweater? Thermal underwear? Do you need to accept it?

Take it all. Winter is also 9- 10 degrees, and it feels quite cold. I put on a down jacket last winter. The climate change of the earth is extremely extreme. It's terribly hot and too cold. Hainan Island is not what it was a few years ago. This year, it has been cold from 65438+February to April, which I have never seen before. When I was in junior high school, I wore an autumn coat at most in winter. Now it's different. The earth is almost finished.
