The "ice" in the name of the ice pier symbolizes purity and strength, which is the characteristic of the Winter Olympics. "Dundun" means honesty, health, liveliness and loveliness, which fits the overall image of panda and symbolizes the strong physique, tenacious will and inspiring Olympic spirit of Winter Olympics athletes.

The mascot of the Winter Paralympic Games, Xuerongrong, is designed and created with lanterns as the prototype. The wishful image at the top symbolizes good luck and happiness; The continuous patterns of the dove of peace and the Temple of Heaven symbolize peace and friendship. Decorative patterns are integrated into the traditional paper-cutting art in China.

Snow, symbolizing whiteness and beauty, is the characteristic of ice and snow sports. Tolerance means tolerance, tolerance and mutual learning. Integration means integration, warmth and mutual understanding.

The mascot of the 2022 Winter Olympics has no gender.

According to the regulations of the International Olympic Committee, mascots can't have gender differences, so Bing Dundun and Xue Rongrong can't "talk", which is also reflected in the upcoming animated film Our Winter Olympics. In this animation, Bing Dun and Xue Rong Rong appeared many times, but they didn't speak, but made a "eyah" sound.

"Once you speak, it's easy to tell the gender. Therefore, when BOCOG signed an agreement with the producer, it was written in the terms that "you should not speak when using the image of Ice Dun and Snow Rong Rong, and you should remain gender neutral". Similarly, when making a promotional film for the Winter Olympics and shooting a film video related to the Winter Olympics, if there are pictures of' ice pier' and' melting snow', generally speaking, you can't talk. " The relevant person in charge of the legal affairs department of the Beijing Winter Olympics Organizing Committee said this in an interview.
