Building on this success, Kong represented Hong Kong at the Rio 2016 Olympic Games. Her career reached a historic milestone in January 2019 when she became the first fencer from Hong Kong to win a World Cup title in Havana, Cuba. Demonstrating her commitment to both sport and academics, Kong earned a Bachelor of Arts in international relations from Stanford University. Kongs distinguished international career continued with consistent podium finishes.
Competing in the women’s épée event, she delivered a spectacular performance, overcoming a 1-7 deficit in the finals against Auriane Mallo to win 13-12. This victory secured Hong Kong’s third-ever Olympic gold medal and marked Kong’s first Olympic medal. As of 2024, Kong is pursuing a Juris Doctor degree at The Chinese University of Hong Kong’s Faculty of Law, with aspirations to work for the United Nations. Following her historic Olympic gold, Kong announced her retirement from professional fencing on August 4, 2024, signaling her intention to embark on new career paths and contribute to Hong Kong.
Just two days later, on August 6, 2024, it was announced that she would join the Hong Kong Jockey Club, where she will play a pivotal role in promoting sports development within the city. Her Olympic success, alongside fellow fencer Cheung Ka Long, has already significantly boosted public interest in fencing across Hong Kong, attracting new participants of all ages to the sport.
