Is it okay to cover a 4 kg quilt without heating in Lijiang in winter?

Of course. Lijiang is located in a high altitude area, with a low temperature in winter and a dry local climate, so even without heating, a 4-kg quilt can provide certain warmth. The quilt is composed of multi-layer fabrics and fillers, which has heat insulation performance. The fabric of the quilt blocks the entry of cold air, while maintaining the body temperature in the quilt. The human body generates heat when it sleeps. The quilt helps to keep heat and prevent it from being lost to the surrounding environment. Covering a 4 kg quilt can form a relatively closed space and reduce the loss of heat.
