So Tsz-ling (second from left) and her mother; medal-winner Evelyn Choy, with her mum.So Tsz-ling, the youngest on the team of 20 who have all had organ transplants, took home three golds, in the sprint, long jump and bowling; a silver in swimming and a bronze in badminton.
Hong Kong came 12th out of 49 countries and territories in the eight-day event, with 14 golds, 12 silvers and 11 bronzes - the best result since 2007, the first time a local team competed in the games which are held every two years.
"I want to thank my mother for her continuous support," said Tsz-ling, who was born with a liver defect. "And I want to appeal to more people to donate their organs to people in need."
Tsz-ling survived - thanks to her mother, Penny Poon Wai-fong, who donated a third of her liver when the girl was seven months old.
"I'm very happy. She has grown healthily after accepting the organ transplant and can show her sporting talent," said Poon.
But Dr Chau Ka-foon, honorary president of the Hong Kong Transplant Sports Association, said Hongkongers still need to be willing to sign up for organ donation.
