At the same time, their perverse behavior and exaggerated style of dress and the strange language constitute the alienation and challenges of a core value system. It should strengthen the ideological review and classification management, with the criticism of the mainstream media to enhance the vigilance of the community, as well as through commercial activities to digest rebel style, which is the effective way to promote the core value system.展开更多
