Yam shared her AAA (art, acrobatics, acting) on stage, in return for combined, no more than, HK$2.00 worth of Christmas gift in the form of a pair of nylon stocking, with more than a dozen enthusiasts, age 10 to 20, for the sake of preserving the art form of Cantonese opera as she knew it for future generations. She asked for nothing else, tangible or intangible, implicit or explicit, from them, except studying hard. Yam was never heard talking about her sacrifices (For example, September 1965 told how not put on new clothes for months. ) in paving the way for her 'next' generation or made any move for her own vanity for close to 30 years, ceding the limelight for benefit of her 'next' generation.
