Why is Zhang Yunxia Yue Opera not very popular?

Why are there so few descendants of Zhang Yunxia Yue Opera? Zhang School is a school of Yue Opera founded by performing artists of Yue Opera, and Cai Feihe, a famous actor of Yue Opera, is the most influential successor of Zhang School.

In 1980s, Cai Feihe was once a red man on the stage of Yue Opera and one of the "Five Golden Flowers" of Hua Xiaobai Yue Opera Troupe. However, Cai Feihe later became a movie star and left the stage of Yue Opera for many years. There are fewer descendants of Zhang Pai, and fewer young actors learn to sing Zhang Pai.
