Mr. Shen Zhenglu, a famous erhu performer, music educator, professor of the School of Music of Nanjing Normal University (now retired). He became famous all over the country in the 1960s, and he has made outstanding achievements in both erhu performance and teaching. Mr. Shen's erhu playing style is simple, mellow in tone, solid bowing, large range of vibrato, and very tense musical performance.

The formation of this style is based on profound folk culture and folk music. The formation of this style has gone through the stage of childhood apprenticeship, the stage of juvenile professional study, and the stage of middle-aged and young people's teaching. It is composed and performed of "Yangguan Sandie" for its erhu. The epitome of mature style.

In this famous erhu tune transplanted from the ancient tune, the 41-string (A key) tuning is creatively used, which expands the erhu tuning type and tonality. It was refreshing and deeply influenced later people's re-creation of "Three Layers of Yangguan".

As a music educator, Mr. Shen Zhenglu insists on the inheritance of traditional music as his educational philosophy. With his solid erhu playing skills, he pays attention to the educational method of teaching students according to their aptitude, and has cultivated many educators and erhu performers who are active in and outside the province, as well as across the country and overseas.

Mr. Shen has been teaching for decades in the School of Music of Nanjing Normal University, which has a profound cultural background. His educational philosophy is a link between the past and the future. The inheritance and practice of Chinese traditional music education has certain reference significance.
