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.

蘇州河邊 (1946)

作曲：懷鈺（陳歌辛）
作詞：懷鈺（陳歌辛）
主唱：姚莉、姚敏

莉：夜留下一片寂寞
　　河邊不見人影一個
　　我挽著你　你挽著我
　　暗的街上來往走著
　　夜留下一片寂寞
　　河邊只有我們兩個
　　星星在笑　風兒在妒
　　輕輕吹起我的衣角

莉：我們走著迷失了方向
敏：我們走著迷失了方向
莉：儘在暗的河邊徬徨
敏：儘在暗的河邊徬徨
莉：不知是世界離棄了我們
敏：不知是世界離棄了我們
合：還是我們把他遺忘

莉：夜留下一片
合：寂寞
莉：世上只有我們兩個
　　我望著你　你望著我
　　千言萬語變作
合：沉默

莉：夜留下一片
合：寂寞
莉：世上只有我們兩個
　　我望著你　你望著我
　　千言萬語變作
合：沉默
