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.

A certain smile
A certain face
Can lead an unsuspecting heart
On a merry chase
A fleeting glance can say
So many lovely things
Suddenly you know
Why my heart sings
You love awhile
And when love goes
You try to hide the tears inside
With a cheerful pose
But in the hush of night
Exactly like a bitter sweet refrain
Comes that certain smile
To haunt your heart again
But in the hush of night
Exactly like a bitter sweet refrain
Comes that certain smile
To haunt your heart again
