                            Wei Zheng-tong especially praised Yan as an excellent  thinker and teacher in his famous book “Confucians and Modern China”. 
  In 1981, “Yan’s Autobiography” was published in Taiwan, which  was the first record of Yan’s contribution to rural construction. The author  emphasized Yan’s popular education movement from 1920 to 1980. Until now, this  book has high value in historical research.

                            Before 1980, Readers Digest published Yan’s  essay for seven times in 40 years, which was a high praise of Yan’s  contribution in mass population. Yan Yi-qiao collected essays about Yan’s  research and contribution and published in 1976 named “Mr. Yan and his mass  education and rural construction.” In  1980, Mr. Li You-ning compiled the book “In Ninties” according to Yan’s oral  account.  |

                            In 1989, Science and Education Press published “Yan Yangchu’s Essays”; in the next year, another book named “Yan and his Dingxian  Trial” came out. In the second book, there were 68 essays written from 1926 to  1936, concerning about Yan’s mass education movement in Dingxian. It has become  the most authoritative work about Yan’s research. Ms. Li Zhi-hui, the staff in  Dingxian Yan’s Research Association, began to search information about Yan  since 1985. In five years, she interviewed more than 20 people and got first  hand oral material. 
                              From May 28, to Jun 1 of 1990, International  Conference about Yan’s Mass Education and Rural Construction was held in  Shijiazhang, co organized by Central Education Institution, Hebei Education  Association, IIRR, and Beijing  alumni association.

                            In 1942, Japanese education experts  began to do research on Dingxian Trial. In 1945, Pearl Buck, the famous American  writer, interviewed Yan about his experience of popular education and recorded  this part in her book named “Tell the People.” This book had great influence in  the world and the UN made the basic worldwide education plan according to it. 
                              In 1980s and 1990s, the research on Yan’s mass education became popular.  For example, Charles W ·Hayford focused on Dingxian Trial and wrote “Folk  Life: Yan Yangchu and China Rural Areas”. Mayfield put emphasis on the  necessary and possibility of long-term development in Chinese rural areas. G.N.  Radi summarized the experience in education, livelihood, health and  self-government in India.  IIRR compiled Y.C.James Yen'S Thought on Mass Education and Rural Reconstruction China and  Beyond and Rural Reconstruction Review.  |
