The syncretism of Confucianism, Buddhism and Taoism in Jin dynasty is manifested by the si-multaneous use of the three religions in national policy-making, which places an equal emphasis on the three religions. In religious theory, the syncretism is displayed by the fact that the three religions try to learn from each other to perfect themselves. Individuals would practice the three religions at the same time, a common feature of some famous scholars. In social communication, the three religions interact with each other in the form of exchanging poems, holding parties and learning doctrines from each other.
