The first pair of contradictions: from the education administrative department and every school, the public interests of the country and society are considered, that is, every student should be trained as a builder and successor of the socialist cause. As every family and every student, they consider the future and destiny of the whole family and children.

The second contradiction is that, on the one hand, with the accelerated development of social economy, the continuous progress of science and technology, the continuous development of various disciplines, and the intensification of integration between disciplines, cross-disciplinary and marginal disciplines are constantly emerging. On the other hand, students' study time and space are increasingly limited. Faced with the ever-expanding disciplines and the endless stream of information spread on the Internet, their physical and mental academic burden is getting heavier and heavier, and quite a few students are often defeated by "learning".
