Qiu Ru pointed out that since the successful bid for the Winter Olympic Games, under the impetus of the strategy of "expanding the south exhibition from the west to the east" and the call to "drive 300 million people to participate in ice and snow sports", the mass events of ice and snow projects have been widely carried out, and more and more people have fallen in love with ice and snow sports, embarked on ice rinks and snow fields, and enjoyed the fun brought by winter sports.
