According to the custom, the center of the Winter Olympic venues should hang the flags of various countries and regions and participating Olympic committees, and this row of flags is called the Ten Thousand Flags, also known as static flags. These flags not only create an Olympic atmosphere, but also give athletes a sense of belonging and honor.
During the Winter Olympics, the National Stadium undertook all men's ice hockey matches and some women's ice hockey matches, with a total of 13 participating flags and IOC flags (repeated countries will not fly them many times), and 4 universal protocol flags (IOC five-ring flag, IIA flag, Chinese flag of the host country and Beijing Winter Olympic Organizing Committee flag).
The confirmation and production of the Winter Olympic protocol flag is a long and rigorous work, and the folds need to be ironed out little by little before hanging. The ice hockey arena has a large flag, with a length of 2.88 meters and a width of 1 meter and 92 meters, and it takes an average of 15 minutes to iron a flag. Seemingly simple work, in fact, there are many "doorways". All the staff members have done this work with a sacred and solemn feeling.
