Political institutions patterned after the Chinese model were imposed, and Confucianism became the official ideology.
The Chinese language was introduced as the medium of official and literary expression, and Chinese ideographs were adopted as the written form for the Vietnamese spoken language.
Chinese art, architecture, and music exercised a powerful impact on their Vietnamese counterparts.
Vietnamese resistance to rule by the Chinese was fierce but sporadic.
Most scholars by now, accept that the Vietnamese are not descended from one single racial group, that they are instead a racial mixture of Austro-Indonesian and Mongolian races.

In 20000 BC, before the first history was recorded in writings, there had been already among people the legends and mythology about the origin of Viet nation from HUNG VUONG.
These are stories on HONG BANG dynasty, offspring of dragon and fairy, bag of hundred eggs, eighteen kings of Hung Vuong dynasty, Son Tinh - Thuy Tinh's conflict, Thanh Giong's victory over An foreign aggressors, folk of betel and areca nuts, "banh chung banh day", watermelon .....
