In the era of all media,the mixture of real information and false information,the interweaving of mainstream culture and subculture intensify the difficulty of moral education in colleges and universities. Symbols can achieve positive matching and coupling with the functional attributes of moral education. Through the encoding and decoding of the symbols of advanced knowledge,college students can penetrate the implied meaning world of advanced knowledge into their blood and bones in the form of collective uncon- sciousness,and complete the psychological identification of the meaning of symbols. Moral education presents a dual logic state of in- ternal and external development. The self - formation logic of moral educationcontains the active meaning of human nature and individ- ual life operation,and the hidden power of moral self - formation exists in cultural symbols. The generation of moral educationis con- fronted with so many difficulties,including the evolution and transformation of cultural symbols,the misreading and dismember of pub- lic identity,the inborn transgression and centrifugation of morality,the lock and siege of the generation of moral education and other deductive difficulties. Therefore,moral education is to generate from inheritance and creation of culture symbol,the public identity of reformed and reconciliation,moral integration of endogenous and heart,the unlocking and breakthrough of moral education to generate such dimensions as logical approach. We aim to achieve moral education in higher education to generate the evolution of the spectrum with each other into its own direction and value orientation,and describe the ideal harmonious alternates and humanities into moral edu- cation.
