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.

我有一段情 (1957-8)

作曲：梅翁（姚敏）
作詞：辛夷（陳蝶衣）
主唱：吳鶯音

我有一段情呀　說給誰來聽
知心人兒呀出了門
他一去呀沒音訊

我的有情人呀　莫非變了心
為甚麼呀斷了訊　我等待呀到如今

夜又深呀月又明　只能懷抱七絃琴
彈一曲呀唱一聲　唱出我的心頭恨

我有一段情呀　唱給春風聽
春風替我問一問
為甚麼他要斷音訊

夜又深呀月又明　只能懷抱七絃琴
彈一曲呀唱一聲　唱出我的心頭恨

我有一段情呀　唱給春風聽
春風替我問一問
為甚麼他要斷音訊
