1930, Yu Yu was 22 years old and was admitted to the Department of Psychology of Xiamen University. /kloc-graduated in 0/934 and stayed in school as a principle teacher. When Yu Yu entered Xiamen University, Master Taixu was the abbot of Nanputuo Temple in Xiamen and the dean of Minnan Buddhist College. Xiamen University is adjacent to Fujian College. Whenever Master Taixu comes here to give a speech or give a lecture, Yu Yu will listen. In the next few years, due to the intermediary contact of Yu Yu, Fujian Academy of Sciences invited more Xiamen University professors to take part-time jobs in literature, history and philosophy courses. This not only improved the knowledge level of monks, but also communicated the exchanges between Buddhism and social sciences. 1932 10, Master Taixu arrived at Nanputuo Temple in Xiamen and gave a lecture on "The Peril of Modern Monk Education and the Future of Buddhism" for students of Fujian Academy. Then, in 1 1 month, at the invitation of "Shirley Society" organized by Xiamen University professor, he took Yu Yu as a record and gave a two-week lecture on "learning only about law". Chronology of Master Taixu 1932 1 1 month records:

"In the meantime, at the invitation of Shirley Club of Xiamen University, the master gave an introduction to legal common sense, and Yu Deyuan (Yu Yu) took notes. This theory was told by Lin, a Buddhist scholar in the world at the beginning of last year, but it was suspended before it was finished. Although rough and comprehensive, it may not be able to analyze the knowledge of the world and expand the knowledge of the dharma. However, it is quite organized. "

The master has given many lectures on understanding before, but due to time, he failed to give a systematic explanation. This time, due to the long teaching time, the system is well organized, and the world is analyzed with simple explanations. The records made by Yu Yuyu were later reviewed by the master and published as an Introduction to Knowledge-only Law. The master invited eleven people, including Wang, Zhang Huasheng, Tang Dayuan, Lin Yanming, Mei Guangxi, Lin Lin, Fazun, Hu Miaoguan and Huang, to make a preface, which shows that the master attaches great importance to this book and its records can also be written as articles.

While teaching at Xiamen University, Yu Yu published his first paper, Learning from the Ming Dynasty, which was highly valued by the academic community. Later, due to the karma of teaching Yin Mingxue in Minnan Buddhist College, he sorted out the lecture notes and published them on the topic of Yin Mingxue on 1936, with the preface of Taixu master yujiang county Kang Hu. Yu Yu taught in Xiamen University for one year, and resigned as a teacher in 1935, and became an editor in the Supervision Institute of Nanjing National Government. 1937, the Marco Polo Bridge Incident, War of Resistance against Japanese Aggression began, the "August 13th" Sino-Japanese War broke out, then Nanjing retreated, the National Government moved to Sichuan, and Yu Yu resigned and returned to Xiamen. Master Hongyi was stationed in Minnan, Xi, and gave lectures at Zhanshan Temple in Qingdao. After the autumn, he was also nervous about the war situation in the north, so he returned to Minnan and lived in Yu Yu to visit Anwanshiyan. Yu Yu likes calligraphy since he was a child. When I was a part-time student at Minnan Buddhist College, I wrote an inscription for Nanputuo Temple. When I was working in Nanjing Supervision Institute, I was under the guidance of Mr. Yu Youren, the president. At this time, I visited Master Hongyi and was inspired by his calligraphy. 1942 10, Master Hongyi died in Wenling Sanatorium in Quanzhou. Yu Yu is a teacher of Guizhou University, and Yao Zeng sent a poem:

Choose the method of Nanshan, chapter all over the world. In the deep group of books, Demai was before the ancients.

There is no hidden feeling in learning, which makes the book fresh. I can't pick up the words, blowing tears and wetting the river.
