What quilt should I cover to go to Hainan?

There are quilts, quilts, silk quilts, duvets, cashmere quilts and so on. So Hainan people usually cover these quilts in winter.

As for what quilt to cover for the winter, it depends on which city and county in Hainan, such as Haikou, Wenchang, Qionghai, Wanning and Chengmai. It's humid, so it feels a little cold in winter and needs to be covered with a thick quilt. For example, in Sanya, Ledong, Dongfang and other cities and counties, the weather is warmer, so a quilt is enough.

Like Wuzhishan City, you'd better cover yourself with a quilt all year round, because the climate in Wuzhishan is very different from day to night, and it's very cold at night. If you don't pay attention, you will catch cold.
