Aunty Fanny and Huang Bi Ren are out as she only came into the scene in the late 80s and became 阿姐 into the 90s. The article refers to the time before YLB and LNX were married. That's a frigging long time ago. ("据知,杨莉冰和前夫李南星仍在拍拖阶段时,曾遇到一名电视台的阿姐介入他们的感情.") It's unlikely to be Xiang Yun and Chen Liping as the term "阿姐” was coined in the 90s, and was always associated with Lao Zoe and Aunty Fanny and Ann Kok. Anyway, I could be wrong.
