On the other hand, we should also respect some habits of Americans. For example, don't let food, don't ask questions about privacy and so on.
Eating is a key link. Try to prepare as many traditional dishes as possible in China. Foreigners, especially Americans, generally like to eat Chinese food, so don't worry too much about the taste. If you go to a hotel, you must go to a clean and hygienic place. The grade is not very important. Going to a hotel that is too high will leave a bad impression on people. You can order some dishes like kung pao chicken and sweet and sour pork tenderloin, which are very popular among foreigners.
In addition, when greeting or leaving, you can send some small gifts. Don't be too expensive, as long as it smells like China. Small Chinese knots or tourist destination medals are good choices.
