Now you call it 'give Vietnam culture'. Just a few day ago a Chinese member called it 'stole Chinese culture'.
China is a big race melting pot. Whatever race or ethnic group in it become mixed and come out as one. Vietnam was thrown in it for 1000 years and came out intact. Surely there must be reasons why our ancestors sook independence from China.
I am ashamed to admit that a number of Vietnamese embrace the idea of becoming a colony for US yet I haven't seen anyone shows the same idea toward China. China is surely unpopular to Vietnamese.
It should also be noted that Vietnam, unlike China, was capable of resisting the Mongol invasion. There were 3 great civilizations in Asia that was able to resist the Mongols worthy of note:
1) Japan (we resisted them on their two attempts in 1274, and 1281)
2) Dai Viet
3) Majapahit Empire
