First, students are complete people. Students are not simple and abstract learners, but complete people with rich personality. In educational activities, students who exist as complete people not only have all the wisdom and personality strength, but also experience all the educational life.

Second, every student has his own uniqueness. Everyone has formed a unique "psychological world" because of the differences in genetic quality, social environment, family conditions and life experiences. They are different in interests, hobbies, motives, needs, temperament, personality, intelligence, expertise and so on. "Different people have different faces." Uniqueness is the essential feature of sex.
