i will travel between 10th august to 10th december this year to shenzhen, china.

Well, August to December is a long time for you to stay. You need to go through the summer, autumn and winter of this city. Summer will be very hot and there may be heavy rain. Early December is cold but not freezing.

So about the clothes, you need to bring summer to winter clothes , such as T-shirts, skirts, jeans, sweaters, overcoats and scarves. Oh , do not forget the rain gear too. Actually, you can buy some clothes when getting there. There are many cheap and fashionable clothes there.
