How was the college entrance examination immigration legal 20 years ago?

Never broke the law. 20 years ago, from 200/kloc-0 to 2002, there was no concept of "college entrance examination immigrants" and there was no borrowing from other places, so all the students admitted were normal and would not be dealt with. The migration of college entrance examination is a very complicated social phenomenon, which has both internal and external causes of education. From the perspective of education, it is mainly a concentrated reflection or embodiment of the contradiction between the unbalanced allocation of higher education resources and the unbalanced development of basic education in China.
