South Korea has floor heating in winter, so there is no need for thick quilts indoors. The thickest feeling is similar to the thinnest in China in winter. If you go to Korea, don't take silk quilts, air-conditioned quilts and big quilts to Korea. It's heavy and useless.
Because South Korea has a high latitude and a high floor heating coverage rate, it is almost a warm environment of about 20 degrees as long as it is not outdoors, so it is also enjoyable to have a cup of cold coffee indoors, and the quilt for sleeping is not a problem at all. It should be okay for girls to wear skirts as long as they are not outdoors for too long.
South Korea's winter anti-health law
Koreans really love slippers. They don't wear them at home, and they wear slippers with various casual or fashionable shapes every day when they go out. Almost a pair of black and white striped slippers can be called "national slippers".
Koreans love American coffee, and iced American coffee is still one of the protagonists in winter coffee shop sales. New Qi Jun often sees girls (yes, I went to a women's university at that time) shouting "Oh, a C froze to death" on the way to class, then holding an iced American cup in her hand and unconsciously pinching the thermos cup in her hand.
