When Ng Kwan Lai paid a visit to the Hong Kong Heritage Museum in 2002, she was so impressed by the work to preserve the relics and legacies of Cantonese Opera that she agreed to donate to the museum over 3,000 items from her own collection of costumes, trunks, stage props, librettos, publicity publications and photographs. The donation represents a valuable addition to the museum’s collections and a significant resource for studying the life and career of Ng Kwan Lai as well as the development of Cantonese Opera and the film industry in Hong Kong.
