What's the climate like in Nanchang? I come from Henan. How should I adapt to it?

Nanchang uses the words of four seasons. Spring is no different from autumn. Summer is very hot, much hotter than Henan, which is famous. Nanchang is not very cold in winter, it is a little cold when it freezes, but it hasn't snowed heavily in recent years, which is ok. You said you could take down jackets with you, which might be useful. After all, after the first winter in Nanchang, I was prepared, and I will get used to it later.

Please accept it, thank you!
