The Chinese knows about that a long time ago. Language changes your brain functions. Why do you think there's that many Chinese. They are not all Chinese or Han.

Some are Mongols, Mien, Hmong, Hui. There's a whole long list of them, and they learned Mandarin and thus the language assimilate them. Without their own written language, it's very easy to assimilate.

U.S did the same with the Natives to try to assimilate or evolve them.
