As we konw, there are many differences between China and foreign countries,because people have different habits and faiths.
Eating habits are different in many countries. The Chinese have a saying, “Eat good things for breakfast, eat a big meal for lunch, but eat less at dinner.” Many Americans agree that one should start the day with a good breakfast, but their ideas about lunch and dinner are different.
Most Americans only give themselves a short time for lunch. So they eat a small meal. After work they will have more time to eat a big dinner. Also a quiet dinner at home with all the family members talking about their day is a way to rest after a long, hard day of work.
If you are invited by a male.Men should wear tidy upper outer garment and leather shoes.Women should wear suit and high-heel shoes. That's dress codes.Buty Chinese usually wear western-style clothes or something which is very simple.
One of the feature of western-style food is: there are a lot of table wares.When we sit down,our eyes will be dazzled.Plate,cuo,knife,folk and so on.But the most time in China,people just use chopsticks or spoon. In my opinion,maybe foreigners really emphasize their etiquette.Chinese don't care about this.
Foreigners may be confused why Chinese donot eat food dropped on a table. Their thought is, "A tabletop has had nothing but food on it. No one walks on it, sit on it or throws garbage on it.In the West, they our tabletops quite well, often with disinfectant, especially in restaurants.
Eating out of a common disk is another different habits. People in the weat use separate serving utensils when getting food from a common dish. They would find 'germ sharing' much more prevalent with people using their eating chopsticks and eating food directly from a common dish or plate.
