The singer-songwriter started her music career as an erhu player. In 1977, she studied playing the instrument at the Central Conservatory of Music and in 1980, she joined in the former Central Orchestra, now the China National Symphony Orchestra.

"I was exposed to different music genres by learning from my neighbors, who were musicians, like violinists, suona (double-reed horn) players and singers. Naturally, I was allowed to complete my own vision as a musician," says Cheng. "One of the most important things they taught me was to enjoy music, whether performing onstage or practicing at home."

Over 1995-96, Cheng went to New York to further her music study, which allowed her to watch musicals. One was The Sound of Music, featuring singer and actress Julie Andrews. In 1998, Cheng, as producer and leading actress, brought the Chinese version of the musical to Beijing, which was well-received by audiences.

Asked about her plans in the near future, Cheng says she is not in a hurry to do anything.

"I have been listening to lots of music and practicing my guitar during my days at home after the coronavirus pandemic hit. I am still writing songs every day. Whether they are published or not, I find the process very satisfying," she says.
