According to the basic strategy of the European and American philosophy shift, with the "Truth and Method", the philosophical foundation and perspective of modern Chinese teaching theory and education management practice are discovered, and there is insufficient reference and need to be studied,optimized and expanded; then reflect on the national conditions and reflect on Qian Xuesenzhi Question,it is found that the relationship between teachers and students ,students and textbook classrooms should not be based on the subject and object positioning method; it can be proved that interpretation and understanding are also permeated in teaching activities.It should be a dialogue relationship between man and the world, and a combination of nature and man.A relationship; the true situation of truth: both sides should be undecided. The open historical horizon of the understander and the open historical horizon of the existence of historical relics should move toward a connection,participate in it,coexist, face the future and be unified,Form a fusion of horizons. The contrast is paranoid rationality, long‐term dominance of natural sciences,teaching activities and teaching theories, which has accumulated many malpractices and hindered the occurrence of truth. The world should go beyond the single subject and object and the correspondence theory of truth, face the infinitely open universe, and realize the effective history, in order to create infinite possibilities and clarify the truth.
