People's enthusiasm has also brought attention to the related shows.

"Without the Olympics, I am afraid that we might not have succeeded to such an extent," Zhang says.

Chen says: "The popularity of the program is also due to its quality. We have carefully designed the script and identified key aspects that have led us to succeed.

"One of the problems was that many viewers lacked relevant knowledge. There would be a barrier when they watch our show, which also features professional sports competitions."

To find a solution, a few professional athletes were invited on the show to explain things on-screen.

"As professional athletes, we have a job here-to introduce a commonsense approach to winter sports shown in the program," says Ma Wei, a short-track speedskater who won the 5,000m competition and broke the world record at the 2016 World Youth Championships.

However, as the TV show was not designed as a professional competition, it needed to be attractive to the audience.

Apart from inviting actors like Wu, the production team also developed various games to make the program interesting to watch.
