Ann Cock, Phyllis Quack, Fanny Wong, Auntie Zoo etc all went overseas to develop but not successful. They are all considered ah jies as well. However, none of them look like 'innocent' type.
It's not any of those u named. It's actually He Jie, who back then always played the sweet innocent young thing with her domesticated look. She left SBC or TCS (Mediacorp predecessors) in what was considered a bold move then to Hong Kong as she was fluent in Cantonese. But she failed miserably and ended up acting in Karaoke Videos, well, not much as an acting actually, u know those low-cost production that features a grl walking about in pensive mood against a famous tourist spot. One of my friends walking in SBC's security outfit said He Jie is well known for placing her arms on men whenever she talks to them, regardless of who u are. Now u know why a drink seller is involved.
