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.

恨不相逢未嫁時 (1958)

作曲：姚敏
作詞：陳昌壽（陳歌辛）
主唱：李香蘭

冬夜裡吹來一陣春風
心底死水起了波動
雖然那溫暖片刻無蹤
誰能忘卻了失去的夢

你為我留下一片春的詩
卻叫我年年寂寞過春時
直到我做新娘的日子
才開始不提你的名字

可是命運偏好作弄
又使我們無意間相逢
我們只淡淡地招呼一聲
多少的甜蜜辛酸
失望苦痛盡在不言中
