"History of languages in Vietnam"

One more thing I wanna talk, that luckily, we saved our language - Vietnamese language and developing it day by day. I am proud of this!

Hello Yifan, about your question, I alreadly mentioned in my presentation. It was because of the 1000-year Chinese domination in Vietnam. Vietnam was under the domination of Chinese feudalism, Chinese feudalism wanted to assimilate Vietnamese people but they did not get the success. Chinese still Chinese and Vietnamese still Vietnamese. By the way, the domination was in the process of 1000 years, the domination left, and things still were there. And language is one of these things. It like colonialism of France, Portugal, Spain, England more then 100 years ago. They invaded the others country all around the world. And now what happened? English, French, Portuguese... became popular in the world: all are in top 5 the most common languages in the world. So do Chinese language.   It is my answer for your question. Thank you!

It's because China invaded and dominated Vietnam (111 B.C) for more than 1000 years. During this time, Vietnam was heavily influenced by Chinese culture and language. Later on, there was a period when the French invaded Vietnam, and that was the reason why French affected the Vietnamese language too.

I saw that in your introduction, there are places to learn from Chinese in Vietnamese. I want to ask, why do you think Vietnamese learns from Chinese instead of other languages? What caused the change in Vietnamese?
