In order to escape from war, Master Yin Shun along with Master Xu Ming, Chang Jue and Guang Fan, fled from Xiamen to Hong Kong in June 1949. Arranged by Li Zikuan, Master Yin Shun sailed to Taiwan on September 3, 1952, and then attended the second general conference of the World Fellowship of Buddhists held in Japan as the representative of The Republic of China. He had been stayed in Hong Kong for 39 months and briefly lived in several places. In these times, he did not forget to promote the Dharma and study the principles of Buddhism. He not only edited the "The Completion of Master Taixu", but also published "The Chronicles of Master Taixu", "Young Buddhism and Buddhist Youth", "New Theory on Pure Land", and other books with academic value. In 1952, he was elected as the chairman of the Hong Kong and Macau branch of the World Fellowship of Buddhists and the chairman of The Hong Kong Buddhist Association. Through this article, I would like to present the relevant (propagation) activities and academic research of Master Yin Shun during his time in Hong Kong.
