Lanza returns to the May Fourth period (1917-1923) and the rise of student activism in and around Beijing University. He revisits reform in pedagogical and learning routines, changes in daily campus life, the fluid relationship between the city and its residents, and the actions of allegedly cultural student organizations. Through a careful analysis of everyday life and urban space, Lanza radically reconceptualizes the emergence of political subjectivities (categories such as "worker," "activist," and "student") and how they anchor and inform political action. He accounts for the elements that drew students to Tiananmen and the formation of the student as an enduring political category. His research underscores how, during a time of crisis, the lived realities of university and student became unsettled in Beijing, and how political militancy in China arose only when the boundaries of identification were challenged.
