"There are more than 100 sports officially approved by the State Sports General Administration, and it is impossible to bring them all into the National Games system. Therefore, while retaining the Olympic Games, we have maximized 19 mass sports, hoping to take care of the broadest needs of the masses. " Liu said: "For example, marathon, roller skating and rock climbing are all popular and fashionable mass fitness projects. Table tennis and badminton are traditional sports with deep mass base for many years, while dragon boat and Tai Ji Chuan are distinctive national sports. In fact, this kind of reform has put a lot of pressure on the organizing Committee, and there are also concerns that' good things have not been done well', but the Chinese sports body should have the courage and responsibility to complete this reform.
