What is college entrance examination immigration? What management measures does the state have for college entrance examination immigrants?

The so-called college entrance examination immigration means that parents or relatives want their children to be admitted to a better university in the college entrance examination, so they take their children's hukou and student status to provinces with relatively low admission scores before the college entrance examination. In this way, children studying in general provinces will be ranked in advance in the college entrance examination in special provinces, thus being admitted to first-class universities.
