Get rid of minority? You have no idea what the real situation in China.In China, minority has much better benefits than Han people. If a child born from a minority and a Han parents, the parents will usually choose minority as his/her ethnity. Because the kids can have additional points at the college entrance exams, they can have two or even three children when Han can have only one child in the past. When a Han and a minority commit the same crime, the minority get less punishment.
In a world like today, are you blaming people moving to other regions just to get jobs? Because that is what happens in China and else where in the world. It has nothing to with “getting rid of minorities”.
