Mr Wang Di, as the first generation of folk music scholars who came out of the Central Conservatory of Music after the founding of New China, made great efforts to rescue and tap the essence of many endangered folk music. Participated in compiling Collection of Guqin Music, Biography of Qin People in Past Dynasties, Integration of Qin Music, Textual Research on Ancient Fingering, Introduction to Chinese Musical Instruments, Preliminary Exploration of Guangling San, 70 Ancient Songs of China, 222 Folk Songs of China, Music Encyclopedia Dictionary, Qin People, Qin Music and Qin Ge, and edited and published them. Mr. Wang Di has made great contributions in inheriting and developing the performance style of Guqin September 1st School, and inheriting, summarizing and perfecting the legacy of Guqin master Guan Pinghu, especially in the excavation, arrangement, production and promotion of guqin music.

1956, she participated in the Guqin interview group led by Mr. Cha Fuxi, and traveled all over the country, and conducted a lot of investigations and interviews on Guqin materials and the status quo of musicians. In addition to collecting a large number of piano music lost to the people, she also collected seven piano music, which made her feel that it is urgent to explore and rescue the art of piano music. She decided to devote herself to the exploration, arrangement and research of piano songs. Under the guidance of Guan Pinghu, she tried to play piano music. Songs of the Oriole, Sauvignon Blanc and Eighteen Beats of Hu Jia were excavated and sorted out, among which Eighteen Beats of Hu Jia was sung at a concert organized by China Musicians Association on 1959, which was well received by the audience, and hundreds of piano pieces were sorted out one after another. 1990 went to hong kong to participate in the Asian art festival "guqin masters meet Xiangjiang river"; 1983 published Qin Song, which contains more than 50 Qin Ge, and has a wide influence in the piano field at home and abroad. 199 1 to 1992 was invited by the Music Department of Harvard University to give lectures in the United States. In 200 1 year, he held a concert of Qin Ge Qin Yun in Taipei, and went to Taiwan Province Province to perform and give lectures twice. After years of hard work, Mr. Wang has excavated and sorted out more than 100 pieces of piano music from more than 20 kinds of piano music widely circulated in past dynasties, such as history, taste, piano music, Song piano music and Zhang Jutian piano music, and asked people to write them in three-line format one by one to facilitate singing and playing. Unfortunately, in 2005, Mr. Wang died in a hurry due to illness, because the content has not been selected and sorted out.

In the mid-1970s, Mr. Wang Di chose some piano music that was easy to sing for teaching, explained the connotation and artistic conception of lyrics sentence by sentence, demonstrated the rhyme of singing and the treatment of music, and trained a group of excellent piano singers. Mr. Wang Di was rigorous in his studies and kept a low profile all his life. As a disciple of Guan Pinghu, a master of the Nine Doubts School, she deserves to be a disciple, but she feels sorry for herself: as a famous guqin player in China, she never recorded a CD for herself, let alone a video product. Her selfless dedication, meticulous work and teaching have left a legacy for Chinese Guqin art, an outstanding representative of China traditional culture and a world-class oral and intangible cultural heritage of mankind.
