Why is it so cold in winter in the north? What should I wear? I came to the north to study for the first year this year. I can't take it anymore. It's too cold. What should I do?

Don't wear too thick, just keep warm. It doesn't matter if you are a little cold, or your body hasn't adapted to the present environment. If you always make yourself look like a polar bear, you will catch a cold in this weather in the north. Many of my classmates are like this, so it is best to keep warm properly. I don't know what to say. Under normal circumstances, a thermal underwear, a small shirt, a down jacket and cotton trousers are the lower body.
