Different regions (地区) have different cultures. Different cultures will form different customs and manners. Some of the behavior we think is polite to others may be rude. Here are some rules about eating.

Russia   Shaking hands would seem to be a polite way to greet someone. However, when in Russia, don’t offer to shake hands in a doorway. It’s said that the “house spirit” live in a home’s doorway and crossing over it for a greeting would bring bad luck.

Italy   In Italy while it’s still generally considered polite to allow a woman to go through a door first. But that rule goes away when people enter a restaurant. By leading in first, the man can be the one to talk to the host and get a table.

India   When in India, avoid eating with your left hand. Because the left hand is seen as disgusting (不洁的). It’s normally used for wiping in the bathroom.The same is true for countries in the Middle East and parts of Africa. On the other hand there are some rude manners that are actually polite in other countries.

The United Kingdom   If you’re in Great Britain, the left is important. You should only pass the port in the direction. Passing the dessert wine to the right is considered as bad manners. If you do forget to pass the port, the person who’s waiting for it may remind you.
