Confucianism provided the principles for political ethics during the Han Dynasty. Most Confucian scholars would raise their social status by engaging in political strategy. Confucianism integrated the viewpoints of Yin & Yang philosophy as well as Taoism into both politics and academia, and made a subtle connection between these two arenas. Many Confucian scholars had become politicians after implementing the ”Comprehensive Mastery of the Classics for Practical Ends”. In the period of West and East Han Dynasty, Wang Mang had begun the political experiment of transforming Confucian scholars into Taoists. The study aims at evaluating his experiment based on the transformation of the Confucian scholars. It explains his ideas and techniques for integrating society and the activity of Confucian scholars into both politics and academia, as well as the inheritance, transformation and influence in theory for transforming Confucian scholars into Taoists.
