On the evening of February 20, the closing ceremony of the XXIV Olympic Winter Games was held in the National Stadium. In order to commemorate the successful organization of this Winter Olympics and meet the needs of the philatelists, China National Philatelic Company Limited (hereinafter referred to as China Philately) specially devised a set of 15 commemorative covers entitled In Commemoration of the Closing Ceremony of the XXIV Olympic Winter Games and issued them on the closing day.

From the perspective of the Winter Olympic mascot Bing Dwen Dwen participating in the Games, Beijing Organizing Committee for the 2022 Olympic and Paralympic Winter Games took advantage of its playful image to convey the characteristics of the 15 events in the Winter Olympics, which not only helped promote the winter sports, but also made the super cute image of Bing Dwen Dwen more popular. Having registered on the stamps the sporting postures of Bing Dwen Dwen in different events of the Winter Games, China Philately had one personalized graphic pattern of the stamp Emblem of Beijing 2022 Olympic Winter Games together with a tag featuring a sporting posture of Bing Dwen Dwen attached to each commemorative cover, aiming to arouse the fond memories of this Winter Games through the cute images. The commemorative covers were released in the form of mystery boxes, so that consumers may have fun in exploring and collecting the covers with hidden designs. Customers buying one commemorative cover can randomly get a cover with one posture of Bing Dwen Dwen, those who buy 15 covers at a time can get the whole range of commemorative covers with all sporting postures of Bing Dwen Dwen.

It is reported that China Philately has issued more than 10 kinds of philatelic products to commemorate the hosting of the Beijing 2022 Olympic Winter Games, and will continue to register the wonderful moments of the Beijing Paralympic Winter Games in the form of philatelic products.
