I just went to college in Zhenjiang this year, and the weather in Zhenjiang suddenly turned cold. What do you need to pay attention to in winter and what to wear to keep warm?

I don't know if you are from the north. There is heating in the north. Even if you only wear long pants indoors, you don't feel how cold it is. Zhenjiang is different. The weather is wet and cold. Even if you wear a cotton-padded jacket and down jacket, you can't resist it. You just feel the cold wind stabbing your bones. Take a hot water bag when sleeping at night (electric blanket is not recommended). Wear autumn clothes, sweaters and down jackets during the day, and add a vest appropriately. Wear a pair of autumn trousers, plus a pair of velvet jeans, or down trousers.
