I will be living in Zhuhai from late August to June. Should I bring more clothes that cater to colder weather or hot?

Hi, Coca.
You mean you will stay in the city from August this year to June in the next year?
If so, I think you need to prepare some summer clothes and some T-shirts, thin coats as well as some thick coat.

The winter in ZH is not so cold. The average temperature is around 12 to 16C in around Jan, so a T-shirt and a thick coat are enough. For other time, T-shirts and thin coats are OK.
