On February 4, 2022, the fourth day of the Chinese Lunar New Year, it was still chilly in Beijing, but spring was approaching, and everything was coming back to life. At 8 p.m., on the big screen of the National Stadium (also known as “the Bird’s Nest”), a countdown of the Chinese “Twenty-four Solar Terms” was being played. The terms were accompanied by the imagery of changing seasons and picturesque landscapes, showing how the Chinese have observed and lived with nature and the world since ancient times.
