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.

月下對口 (1956)

作曲：姚敏
作詞：陳蝶衣
主唱：姚莉、潘正義

姚：天上的明月光呀照在那窗兒外
　　你不要費疑猜窗裏人也沒有睡
　　我不是睡不穩呀只因為你要來
　　守在那窗外靜等待所以窗不開
　　你不要費疑猜窗裏人也沒有睡
　　守在那窗外靜等待明白不明白

潘：你生來好風采呀像仙女下凡來
　　人嬌美歌輕脆彷彿笙歌天上飛
　　我聽了你歌唱呀心花兒朵朵開
　　只希望和你長相偎永遠不分開
　　你唱歌我跟隨一天聽個千百回
　　只希望和你長相偎永遠不分開

姚：我是個農家女呀缺少那好風采
　　你讚美我慚愧烏鴉難與鳳凰配
　　我只好鄉村待呀永遠不離開
　　自己種花兒自己愛等著那花兒開
　　等花開把花採自己採花自己戴
　　只能夠常在鄉村待永遠不離開
合：永遠不離開
