For Vietnamese : If someone curse you, you SHOULD NOT CLOSE the topic ESPECIALLY ON YOUR LAND. You have to show to that stupid guy he is stupid. I evaluate a person on his/her individual. And that Chinese guy in my opinion is very stupid (remember I don't say all Chinese, I say that stupid guy only).
The symbol of Vietnam as I know is "chim ha.c" God bird on heaven or something. (don't know its English word) "do`ng ma'u la.c ho^`ng" is also a famous quote. But I myself have to admit the fact that China influenced our culture a lot. During our history, China always tried to make us become one of its provinces but luckily Vietnamese is smart, even our country is small, their country is so large, they still can not do anything, We are still a country
