"In 1975, Professor Rong Hong of the Music Department of the University of Pittsburgh in the United States invited Du Huan, a blind master of Dishui Nanyin, to sing Nanyin songs at the Fulong Teahouse in Sheung Wan, and recorded them on the spot. It shows the ups and downs of his life. Now, the Leisure and Cultural Services Department, the Museum of History and the Department of Music of the University of Hong Kong are working together to insert interview clips of Nanyin researchers and lovers from all sides on the soundtrack, and it has become a precious Nanyin documentary."
