What to take
The clothes you need will depend on the time of year that you visit. In northern China, from November until March you will require a down jacket, gloves, sweater, warm socks, thermal leggings, sturdy footwear, and lip balm. During the same season in the south, you still need a sweater and warm clothes, even as far south as Hong Kong. In summer, across most of China, you only need loose-fitting shirts or t-shirt, and thin trousers. Shorts will also do, though not many Chinese wear them. Bring a first-aid kit, raincoat, sun hat, deodorant, pocket knife, flashlight, and some good reading material.
