While you are definitely not required to bring anything at all, presents in China are generally always well received. If you do want to bring a present, anything from your home country that is not available in China, like local food, a picture book or souvenirs can be a good idea. Tip: during your time in China you will most likely meet quite a few people who will have gone out of their way to help you with your life here and whom you might want to thank in some way. Bringing a couple of “back-up presents” from home can be a good idea.
