How do Chengdu people in Sichuan adapt to the weather when they go to Harbin to study?

Sichuan is hot and humid, while Harbin is dry and cold. Especially when school starts, Harbin is already very cold, so we should prepare some autumn clothes and thick coats when school starts. Now Harbin needs to buy down jackets, but Chengdu's is not thick enough.

Although it is very cold in winter in Harbin, the indoor temperature is very high, especially in schools. The heating is very good, and the temperature difference between indoor and outdoor is very large. So when you first start heating, it is easy to get angry. Prepare some anti-inflammatory drugs, Niuhuang Jiedu tablets and the like. It is easy to get angry when you come to Harbin from the south, especially when you are just heating. When sleeping, the temperature difference between indoor and outdoor is very large. When you are angry, your mouth and throat are easily inflamed.
