Confronting the era of change in rural economy and problems of the new generation of the migrant workers, the writers of the grassroots novels acutely grasp the ideological status of the new generation of the migrant workers and then make artistic response to the contemporary social reality. In this paper, the two keywords of" Identity Approval" and" Love Narration" are used to illustrate the anxiety feelings of the inward world of grassroots people and their identity approval crisis based on their living experience between rural -- urban areas, however, the grassroots novels use the strategy of love narration to mitigate the anxiety of the identity of the protagonists.
