This is a funny thing for a westerner, but in China most restaurants do not have napkins on the tables and most public bathroom facilities do not have toilet paper or paper towels. So be prepared and have packages of tissue on your person at all times! Enough said!
There could be a couple more things I might share like “you can find any product you could want or need” here in China either in the city or on the online shopping site called Taobao. And, “give yourself time to adjust to the differences in food, thinking, and just being here in China”, and you too may find you're quite simply happy to be living in a less stressful manner and in a safer place, too.
