As we all know, China has a very distinctive culture to the west, and you may come across a few things from not too familiar with it.
The first thing is to take enough beauty products for ladies who wear makeup, as makeup products in China are more expensive than in the UK and the US. As everyone is of a fair complexion in China, it will be impossible for the ladies of colour to look for foundations, concealers, powders, or whatever it may be for your skin tone.
Also, do make sure that you figure out how you are going to manage your hair. If you tend to go to the salon to get your hair done, find a hair shop or salon that caters to African-Caribbean hair.
Be friendly with the Chinese, and you will soon find that you will be accepted in their culture and society.
