In addition, the pictograms for the 2022 Games were inspired by Chinese calligraphy and seal carvings.

Some of the 2022 Games venues embody the essence of Chinese culture just as eloquently. The "S-type" curve of the National Ski Jumping Center, located in the Zhangjiakou competition zone, is nicknamed "Snow Ruyi" as it resembles the shape of a "Ruyi", a traditional Chinese ornament symbolizing good luck.

Technology such as driverless cars, 5G-enhanced transmission and cloud-based broadcasting will also be on show during the 2022 Winter Games.

For the first time in the history of the Olympic Games, Beijing used carbon dioxide in ice-making procedures. Not using ozone layer-harming Freon as a refrigerant in ice making is expected to help reduce carbon emissions equivalent to that of 3,900 cars per year, and cut emissions from the activity to nearly zero.

"The new ice-making technology can precisely control ice temperatures and will be helpful to ensure a standardized hardness of ice surfaces. It will also significantly save electricity during ice making," said Yu Hong, head of the technology department of the Beijing 2022 organizing committee (BOCOG).
