Since the early 1980s, as a result of open policies, Beijing is undergoing an amazing structural transformation and tremendous growth. The huge changes in the Chinese capital gradually forced its residents to face the challenges of managing the structure and culture of the urban environment in order to meet the challenges of the new city. At the same time, emerging nationalism and the development of local and international tourism have made Beijing a showcase for national identity. Day after day, Beijingâs traditional dwelling houses (siheyuan) and hutong were destroyed, disintegrated and rebuilt, turning the capital into an international metropolis. This article focuses on Zhang Daliâs graffiti and performing art works in Beijing. He is one of the artists most concerned with urban transformation. The human head image that invaded Beijing's urban landscape in the 1990s was called "dialogue" and this image was often found on walls and buildings that were designated as demolition. This is a symbolic symbol that cannot escape attention. Investigating Zhang's works through theoretical methods, discusses the relationship between subject performance and spatial transformation, and puts forward the key issues of public space art agency.
