Yam was the "speak softly and carry a big stick" member of Cantonese opera community but without cult of personality character. Entourage (hospital, airport, etc.) around her could become out of control if she allowed it. (For example, construction, medical and legal professionals at a certain pay grade were not allowed to advertise out-right in the past. Getting in the limelight with celebrities was an alternative or even better deal. The resulted stream of "an upscale clientele" was worth the time and expenses.) However, the residue value of her ""down-ballot effect"" is minimal for her co-stars. The last two, Lam and Loong, who played second fiddle to her on stage as second leading "men" continue to be "super idols" for decades.
