There are many differences in eating habits among China and western countries. Firstly, Chinese people ate rice, noodles, vegetables and meat when western people prefer bread, milk, salad and steak. Secondly, westerners used to eating with a knife and a fork, but the Chinese eat with chopstick. Thirdly westerners usually eat quiet instead of making a loud noise during meals. They think it is very much impolite. However, this is common for the Chinese to talk with family members and friends while have dinner. Anyway, it is considering bad manners in both China and western countries to talk with our mouths full.
