Professor Li Yiu-fai, a retired university educator and recipient of the 2023 Hong Kong Humanity Award, dedicated an astonishing 40 years to manning suicide prevention hotlines. His commitment extended beyond The Samaritans, leading him to volunteer with hotlines for Médecins Sans Frontières (Doctors Without Borders) and the Red Cross, as well as pursuing training as a life coach. Last year, he also published an e-book chronicling his life's journey.
