In order to explore the similarities and differences among the "Petty bourgeois" factors in the various periods of Chinese film, this paper traces the evolution of the "Petty bourgeois" factors in the context of the Mao era, the Deng era, and the globalization era, respectively. First of all, under the Guidance of "Literature and Art Serving the Workers, Peasants and Soldiers" in the Mao era, film became a tool for propagating the ideology of class struggle. Elements of petty bourgeoisie literature such as "Individualism, Critical Realism, Sentimentalism" were abandoned and obscured in the film. The urban petty bourgeoisie was the main cinema audiences at the time, but it was not the subject of film creation. Second, in the era of Deng, as the reform of the social commodity economy, the traumatic literature film with the characteristics of "Individualism and Sentimentalism" was popular with the public. "Petty bourgeois" elements of literature and art abandoned by the Mao era began to return to the stage of history. Especially in the late 1980s, the "Wang Shuo Literature" movie, which depicts a special youth class in modern Chinese society, opened the prelude to the "new" Petty bourgeois era. Finally, with the return of Hollywood films to the Chinese market in 1995, Chinese films entered the era of globalization. Hollywood films produced a large amount of "new" petty bourgeois with the aesthetic taste of "Western middle class." With the rise of "new" petty bourgeois, films which expressed romance, rebellion, sentimental, comedy have become part of China’s diversified film market. Students and urban youth with “new” petty bourgeois character became the subject of the “new” petty-bourgeois films. The main body of Chinese film creation has taken a step closer to the image of a multi-faceted public image.
