This paper researches on Tang Hui's case

putting it into the background of new society movement to study on the interrelation between media and social conflict events. Through research we believe that the framework formed by mainstream media represented by party newspaper and the framework formed by market media are the results of media development in nation-society framework. Reports of media represented by Southern Weekly to Tang Hui's case reflect the contradiction between professional concept and objective reality when it comes to the reports about China's underclass rebellion politics. Different from former research results which believe the important role of media in social mobilization and recognition construction

influence of social mobilization on Tang Hui's case is limited. Collective identity constructed by media is self-identification. Because of the reports of media

Tang Hui's case is more obvious as underclass rebellion politics. Mass media are not only the reporters of this rebellion movement

but also participants of this rebellion movement.
