The problem of children's college entrance examination

The score in Heilongjiang is lower than that in Liaoning, but if the registered permanent residence stays in Heilongjiang, your children will have to go back to Heilongjiang a few months before the college entrance examination before they can study in Heilongjiang. I am a high school teacher. If children can adapt to the environment, they can transfer one semester before the college entrance examination. Many of my students do this.
