Since the early twentieth century, Hong Kong has always been an important venue for Cantonese opera development. After 1949, as a result of political turmoil in the Mainland, performers and troupes converged and resettled in the territory, leading to a tremendous prospering of Cantonese opera in the subsequent decade. This development is linked intimately with the rise of the electronic media.
Performers and troupes began to grasp the possibilities offered by film and radio to re-examine age-old performance practices with regard to acting, singing, script writing, instrumentation, and stage set-up. They brought in novel elements from the theatre and movie world, and participated in the production of films and records. With these acts, they are extending the movement to modernize Cantonese opera that began in the 1930s.
Wong Jum-sum was thoroughly immersed in the world of Cantonese opera from young. Through his close encounter with master performers like Hung Sin-nui, Ma Si-tsang, Yam Kim-fai, Pak Suet-sin and Tong Dik-sang, he witnessed first hand the modernization of Cantonese opera, and was mightily moved by the adventure and passion he saw.

毛毛雨,打不冷她的心,
微微風,吹不走她的情;
微風細雨她笑瑩瑩,
噯呀呀!笑瑩瑩。
是什麼,叫他忘了形?
是什麼,叫她笑臉迎?
風吹雨淋她不驚,
噯呀呀!她不驚。
毛毛雨呀,叫我驚一驚,
毛毛雨呀,叫我醒一醒;
他是痴心我多情,
他是痴心我多情,
噯呀呀!莫痴心。
落花呀,雨中片片輕,
柳絲呀,隨風搖不停;
痴情偏逢郎負心,
噯呀呀!郎負心。
毛毛雨,下個不停,
微微風,吹個不停;
微風細雨冷清清,
噯呀呀!冷清清。
