One of the most basic elements of traditional Chinese Buddhism is the construction of Buddhist monastery System and caste system, which is the underlying support for Buddhist existence and purging human souls and society. Modern master Taixu’s thought of the Buddhism revolutionary was focused on the theory, property and system, which in a great level be aimed at the lax and useless of system of Buddhist monastery, so we could say that only Buddhist systems are the basic problem about doctrines and property. Only solve the problem about design and construction of Buddhist systems, then will have the last and best solution for the problem about doctrines and property of Buddhist. Master Sheng Yen was trying to restore real Buddhist faith in his life, and also committed himself to reform and develop the master Taixu’s and Yinshun’s thought of humanistic Buddhism, and based on the perspective of the real faith and modernity of Buddhism, he had constructed and interpreted Chinese Buddhism modernity and deeply, and had constructed in close combination with the spiritual, faith and system, finally presented to modernity construct of Chinese Buddhism belief systems. Actually, Buddhism system is a kind of behavior rules, and is a kind of belief pattern for guiding action with faith, and is a kind of value standard for guiding social and purging human souls, and also is a way to lead social action, those will make other people's ideas and behavior more certainty and predictability, finally it will provide a certain structure for social interaction. This paper starting from the theory and method of the Buddhist sociology, centered on Master Sheng Yen’s thoughts about Buddhist precepts and system construction, to gather and discourse his relative writings, and then discuss the modernity construction about patterns, sangha, caste and institution of Buddhist.
