First.
I give advice about language.
I think Korean language is very important for making friendly.
so foreiger will used polite expression.
Foreigeners say "Hello" to adult, but Koreans say "안녕하세요" to adult.
If i say "Hi" to Korean adult, they are thinking about you an ill-mannered person.
Also to bow down is deference for a person's elders in Korea, so you must be bow down and say "안녕하세요" to adult.
Then Korea people think about you have person of manner.
Second
Do you know yanban dari?
It is sitting cross-legged on the floor
It is Korean people pose when they are seat down.
But foreigners practiced sit in a chair.
So you little feel inconvenient.
I say that because Korea food store not have a chair than floor.
So if you eat traditional Korea food, you will sit down on floor.
Don’t be put off by that.
It is Korean culture.
