Hi, I'm leaving for Guangzhou in 1 day time (11 Nov) and staying til 27 Nov. I understand the weather there now ranges from 16 to 24 degrees but have also heard that Guangzhou is not a very cold place. What sort of attire is suitable for my trip? Is polo-tee and jeans suitable clothing to wear during the day or should I pack many long-sleeved shirts?

Thank you in advance!
