In this regard, Liu Jingmin, vice chairman of the Beijing Olympic Games Organizing Committee, once said that a high-level Olympic emblem not only plays an important role in promoting the Olympic spirit and hosting the city, but also is an important condition for attracting sponsors. The emblem of the Beijing Olympic Games enjoys the treatment of cross-protection, which means that it can be protected as an Olympic symbol, and it can also be regarded as that before August 3, all products that were engaged in commercial activities under the banner of the organizing Committee and marked as developed by the organizing Committee were all fake. Starting from August 3rd, this formulation will change, and the organizing committee will launch five or more series of licensed products, such as commemorative medals, key chains, stamp products, postal souvenirs and other special signs for protection, and can also be used as trademarks and copyrights for protection.
