Buddhism missionized among the upper and lower strata through Taoism and witchcraft at its first period in China. Making use of the Scriptures of translation and the rising metaphysicis, Buddhism monks got touch with Chinese intellectual and enlarged their influence on these people.This is a base that Buddhism missionized successfully in China. In contrast to Buddhism, Nestorianism is different from Buddhism, Nestorian missioners did not make themselves develop in the intellectual and populace, they place their focus on royal palaces and did a lot things that were nothing to do with mission, such as made exotic things for Chinese emperors, participated in government and political affairs. Overdepending on ruler eventually led to missionary failure of Nestorianism in China.
