I don't know where you come from. To tell the truth, Lishui is a bit cold in winter. If you come from the north (with heating), the humidity and cold in the south will drive you crazy. The coldest weather must be below 0 degrees (frost weather will freeze, not much, but it will be fatal when it comes). Sweaters and thermal underwear must be worn unless you want to be "freezing beautiful", so I won't stop you. If anyone dares to wear underpants in Lishui for the winter, even thin underpants in autumn, unless he stays in an air-conditioned room every day, I guarantee that he will not see the sun next spring. Normal people, Lishui winter lower body inside and outside two pants (especially girls, pay attention to leg warmth), upper body underwear, sweater, coat (if it is a down jacket, you can hold it without a sweater). Ps: Dude, it's too hard to have a typhoon in winter.
