The use of 5G tech will allow staff to instantly measure people's body temperature, use facial recognition and conduct registration with just one scan.

Medical and volunteer services are also being optimized to ensure a safe and smooth Games.

With the medical transport system tailored for use in mountainous areas, and facilities and equipment at nearby hospitals upgraded, China's snow medical service is fully prepared for the Games.

In order to provide the best medical and emergency care, more than 10 hospitals in Beijing and Hebei province have assembled an expert team of clinical personnel, with recruitment beginning in 2018.

Starting on Tuesday, up to 200,000 volunteers will serve the Games. They will be responsible for tasks such as providing information, translation services, and support for people with disabilities.

More than 2,000 people with disabilities in China applied to be volunteers at the Games. Among the successful candidates, the youngest volunteer is 19 years old and the eldest 63.

The volunteers underwent four stages of training－general, professional, venue and on-the-job training－which comprised 23 courses.

Li Jian, deputy head of the volunteer headquarters, said that the authorities will take measures to ensure the volunteers' safety under strict epidemic control and prevention rules.

Huang Zhenxiang is one of a number of volunteers to have participated in the 2008 Summer Games in Beijing. Now he is a volunteer manager at the National Snowmobile and Sled Center in Beijing.

"I was in middle school in 2001, when China won the right to host the 2008 Olympics. I saw people in Beijing celebrating this achievement in the streets," he said.

Speaking at a news conference earlier this month, Han Zirong, secretary-general of the Beijing 2022 organizing committee summed up the general mood in the capital, saying: "China is ready to host the Games. After more than six years of meticulous preparation, the Beijing Winter Olympics are ready."
