About polite in my city

Hello, everyone.
I'm Jeff.

Today, I would like to talk about polite in my city.

Some people said: different country, different custom. I agree with them.
In Tsingtao:

1. When we meet someone older than me, we need to shake hands
2. When we meet someone first time, we need to bring something.
3. When we start eating, old people and kids first.
4. When we go downstairs with old people, we should support them with one's hand.
5. When we meet everyone or date, we can't late.
6. Family dine together, young people should initiative toast for old people.
7. When we are going to restaurant, we should waiting for old people sit, we can sit.
8. If we want to going to friends house, we should telling them early, no surprise!!!!
9. When we eating food near the children, we should give children first. When my friends come to my house, I should make tea.
