30% to 20% discount, the general teaching and training institutions will give 70% to 20% discount if they are teachers' children for education and training, and then the preferential strength of each teaching and training institution is different in this case.

There may be some teaching and training institutions, and the preferential intensity is relatively large. There may also be some teaching and training institutions, and the preferential intensity will be relatively small, that is, the preferential intensity will be relatively small. Then in the teaching and training institutions, if the teacher's children can go, they will generally be discounted.

There are also a small number of teaching and training institutions that just don't give preferential treatment and treat them in some ways as ordinary students. So the final conclusion is that teachers and children in general teaching and training institutions usually get a 20% discount.
