I am a student learning English.
I wrote off-hand. Could you check if there are some strange expressions?
(I made a question and I am confused when saying "table manner"
a table manner, the table manner or table manners?)

Q: Could you tell me the table manner of your country?

A: There are few things special. It is kind of Universal. Like western culture, it is also considered as an improper behavior to rest your chin on your hand at the table. Plus, we usually share side-dishes, so to root food around with individual chopsticks is out of manner. Generally, kids who eat only what they wants tend to do it in order to sort out what they don't want like carrots or onions. Parents don't allow it, and then they can naturally learn table manners and develop healthy eating habits. One more thing is that old generations don't like people nibbling food. They prefer those who eat with relish. I think this is also Universal.
