The temperature outside is not below zero, and it is particularly cold at home. Without heating, it will not be below zero.

Usually it's MINUS 2~3 degrees outside, and if you don't turn on the heating at home, it will only reach about 0 degrees without ignition.

Feel cold and wear thin and soft clothes; Wear warm but fluffy clothes in the middle; Wear a windbreaker on the outer layer. At the same time, try to tighten the neckline and cuffs. If the weather is very cold, you'd better wear a scarf, a hat to reduce the heat loss on your head, and a pair of platform shoes to avoid "cold starts from your feet".
