1. Winter should also be divided into northeast, north and south China, right? Winter in Harbin can't be covered with the same quilt as winter in Guangzhou.

2. It's winter in the same place, so quilts should be divided into quilts, silk quilts, duvets and hollow cotton quilts, right?

3. If it is in Jiangnan, South China and Southwest China, there is no heating facility in winter, and the quilt is over 8 kg, the silk quilt is 6 kg and the duvet is 5 kg.

4. In terms of comfort, silk quilt is the best; From the price point of view, the quilt is the lowest; From the perspective of health care, silk quilt is the best! I don't like duvet. The smell alone makes it difficult for people to sleep peacefully, not to mention the threat of mites.
