printing the picture of "Bing Dun Dun" on T-shirts or clothes as a clothing logo, in which case unauthorized use constitutes infringement of trademark rights.

according to China's regulations on the protection of Olympic symbols, no one may use the Olympic symbols for commercial purposes without the permission of the International Olympic Committee or the Beijing Winter Olympics Organizing Committee. Only the global partners of the IOC, the official partners and sponsors of the Beijing Winter Olympics can use the Olympic symbols such as the Ice Dun Dun commercially according to law, and the licensed manufacturers and sellers of the Beijing Winter Olympics can produce and sell licensed products with the image and name of the Ice Dun Dun Dun. It is free for a company to make ice pier pendants by hand, but if participants have to buy tickets to participate, it is a commercial act of drainage. Similarly, it is also a commercial act to sell coffee, jewelry pendants, cakes and other commodities or provide services. It may constitute infringement for a merchant to produce ice pier toys and dolls without the permission of the right holder, or to use the pattern in peripheral derivative products such as clothing, jewelry and food.

Spontaneous production and use If it is not for commercial purposes, people make their own ice piers, such as carving ice piers with oranges, dough version or rice ball version, etc., only for their own entertainment and their families, which generally does not constitute infringement. He Jianqing said that if an individual simply makes it out of his love for the ice pier and is only satisfied with enjoying it by himself and his family, it is generally not infringing. For non-commercial use, it should be used within the scope of license. However, if the ice pier is made into a variety of patterns similar to expression packs without authorization and spread on the Internet, even if it is not used for commercial purposes, it is also an infringement if it is not approved by the Winter Olympics Organizing Committee.
