In 1949, a whole group of multi-talented stars moved from Shanghai to Hong Kong. Mando pop rose to prominence, rivalling the presence of Canto opera music and Canto pop in a short period of time. The young Wong Jum-sum frequented radio stations and recording studios with his harmonica band members, in that process encountered in person many of these Mando pop stars and maestros, including illustrious names like Li Xian-lan, Bai Guang, Yao li and Yao Min. He also regularly collaborated with Filipino musicians who once illuminated the nightclubs of Shanghai.

These stars and musicians created a reservoir of Mando pop songs in the 1950s. The latter formed an inexhaustible treasure trove for radio music program presenters of the time.

Jajambo
你看我　我看你
你看我幾時我有這麼高興過
你看我 我看你
你看我幾時我有這麼得意過
你可不必問我
這麼高興　這麼得意　這麼快活
到底為甚麼　就是你來問我
我也不想　我也不能　我也不會
老實對你說

Jajambo Jajambo Jajambo
Jajambo Jajambo

一定要我說　也不過模模糊糊
迷迷惑惑　Jajambo
還是別管我　也可以免得討厭
免得囉唆　Jajambo
Jajambo Jajambo Jajambo
Jajambo Jajambo Jajambo
還是別管我　也可以免得討厭
免得囉唆　Jajambo
Jajambo Jajambo Jajambo
Jajambo Jajambo Jajambo
