Hong Kong doctor, musician and HYROX athlete goes viral after rescue on Japan flight

The middle-aged male passenger suddenly lost consciousness mid-flight, Hong Kong outlet Dim Sum Daily reported. Cabin crew began administering first aid and made an in-flight announcement asking whether any medical professionals were on board. Cheung volunteered without hesitation, coordinated with flight attendants and provided medical assistance, according to the same account.

A fellow passenger later recounted the episode on Xiaohongshuthe Chinese lifestyle platform known internationally as Little Red Book, describing Cheung as “a very handsome man, over 185 cm tall” who stepped forward calmly under pressure, Singapore-based outlet Mothership reported, citing China Press. Within hours, netizens had tracked down his identity.

Cheung’s profile drew further attention for combining medicine, music and elite fitness. He graduated from the University of Hong Kong’s medical school in 2018 and previously worked in the Accident and Emergency Department at Queen Mary Hospital, one of the city’s main public teaching hospitals, Dim Sum Daily reported.

He is also a singer-songwriter and guitarist whose original tracks, including “The Risk of Driving,” have accumulated more than 700,000 streams across major music platforms. His Instagram bio identifies him as a “doctor, musician, HYROX ambassador,” referring to the global indoor fitness race that pairs eight 1-km runs with eight functional workout stations.

Cheung addressed the unexpected attention in an Instagram post titled “Thank you for the love from Xiaohongshu.” He thanked new followers and longtime supporters, said the wave of attention had left him feeling somewhat overwhelmed, and wrote that he intended to keep focusing on being the best doctor he could be, releasing honest music, and chasing personal fitness goals, including an unbroken set of wall balls and a sub-60-minute HYROX race, Dim Sum Daily and Mothership reported.

A sub-60-minute HYROX is an elite-level benchmark; most amateur men finish in the 75 to 90-minute range.

This is not Cheung’s first brush with public attention. In a November 2023 profile in the South China Morning Posthe spoke about stepping back from full-time public hospital work to pursue music, telling the paper that a six-month sabbatical earlier that year had been “the happiest I’d been for a long time.” He returned to hospital work briefly in July that year before quitting in October to commit to songwriting. Witnessing how fleeting life could be in the emergency room, he told SCMPwas part of what pushed him to seize the moment.

Online reaction on Xiaohongshu and Hong Kong platforms has been overwhelmingly positive, with users praising not just Cheung’s medical instincts but the willingness of an off-duty doctor to step in publicly.

Mid-flight medical emergencies have been common. A 2025 Duke Health study published in JAMA Network Open analyzed more than 77,000 in-flight medical events and found that roughly one in every 212 commercial flights involves a medical emergency. Medical volunteers among the passengers, often physicians, assisted in nearly a third of those cases, the study found.
