Just look at what they do here in North America.
The Chinese and Koreans are pretty good in terms of education.(Model citizens.) Many of them are professionals now. They are law-abiding.
Vietnamese came here since 1980's and they took over China town and the inner cities. They do drugs, prostitution and exhortion of small businesses.
Clean yourself up before laughing at the model citizens of Chinese descent.
The image of Orientals built over a century through the hard work of generations of Chinese immigrants has been shattered overnight as soon as we have accepted planeloads of Vietnamese refugees.
Whenever you want to get a free ride of the bandwagon of anti-Chinese hate-mongering when the white racists are doing it, look at yourself first. Buy a mirror or get a bucket of water.
