This article explores the ideological characteristics and practical performance of Zhao Puchu, the representative of the second generation of Lay Buddhist in Humanistic Buddhism. At the age of 20, Zhao Puchu (1907-2000) served in the Chinese Buddhist world and had contacts with the main characters in the organization: Yuanying, Taixu, Yingci, the 9th Panchen, Wang Yiting, Huang Huanzhi and others. He was the president of China Buddhist Association and the president of China Buddhist Institute. At the age of 40, he was summoned by Master Taixu to the Jade Buddha Temple ten days before the Master passed away and was presented with the newly published "Life Buddhism" by the Master. Ming Shan Master considered this as the symbol of passing on the huge task of carrying forward the development of Humanistic Buddhism. In the direction of the overall development of Buddhism, Zhao Puchu directly inherited the theory of Humanistic Buddhism from Master Taixu. He claimed that the relationship between Humanistic Buddhism and Being Buddha is "Buddha's conduct", which shall be used to "Purify the human world and Build the pure land on earth." The focus of his Humanistic Buddhist theory is not to "talk accordingly", nor to "talk continuously", but to "action continuously". How to avoid the same mistake as Master Taixu's past failure of Buddhist revolution? How to achieve right directions in right ways? All of these are his core concerns. After the establishment of Chinese Buddhist Association, he served as the Vice President and secretary general, and then President as well as secretary general. He has been the leader of the association for many years. Uniting the consensus of all association members, working together to promote Master Taixu's Buddhism Revolution, and to realize Master Taixu's ideal of Buddhism reformation... all of these should be Lay Buddhist Zhao Puchu's core ideas and practices for Humanistic Buddhism.
