Korea culture "Respect"

Have you ever been to Korea ? And have you ever heard about Korea culture ?

We have two different ways to say. One of it is for friend, it is called "Banmal", the other one is for older people, it is called "Jondaemal". We have to repect elderly people.

For example, when you have a meal with older people you have to pick your spoon up after older people pick it up. As you know, when you meet older people you have to bow. When you drink with older people you have to turn your body.
If you come to Korea you should do that when you meet Korean.
