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.

我們歡歡喜喜一起上學校
我們高高興興一起做體操
鼓聲砰砰蓬蓬響
就搖搖擺擺跳
有誰不會我就來教
怪模樣不要笑不要笑
伊呀恰恰恰恰恰
大家跳別害躁別害躁
伊呀恰恰恰恰恰
你跳倫巴不時髦
你學森巴沒情調
只要你試一遭
就知道恰恰妙
跳恰恰多輕巧
你有清清楚楚伶俐的頭腦
你有結結實實靈活的身腰
請把拍子聽得準
把步子記得牢
你別害怕誰都能跳
快狐步太單調太單調
伊呀恰恰恰恰恰
圓步舞太古老太古老
伊呀恰恰恰恰恰
你跳倫巴不時髦
你學森巴沒情調
還不如曼波好
還不如恰恰妙
跳恰恰多輕巧
恰恰恰恰恰恰恰恰恰
伊呀恰恰恰恰恰
恰恰恰恰恰恰恰恰恰
伊呀恰恰恰恰恰
不怕你身體搖
只怕你不肯跳
跳恰恰多輕巧
