Qualifying as a ski doctor requires a diverse range of skills－combining medical knowledge, English-language proficiency and, of course, skiing ability.

"Since 2018, we've visited a resort for ski training for around a month each year to ensure that we could reach the injured people as fast and as safely as possible," said Li.

Ski doctors are required to reach an injured person within four minutes, but in fact, often arrive within one minute.

Li added that they have been given professional training for first aid, and online and offline English training to ensure that they can communicate smoothly with foreign athletes and staff in international events.

"Because our work environment is not based in a hospital or a medical station, all our rescue equipment and supplies must be carried with us," Li said.
