Chaiqian (Demolition) is a portrait of urban space, migrant labor, and ephemeral relationships in the center of Chengdu, the capital of Sichuan province in western China.　Focusing first on the formal dimensions of the transforming worksite – including the demands of physical labor and the relationship between human and machine – the film gradually shifts attention to the social dynamics of a group of thirty men and women who have come from the countryside to work in this ever-changing urban landscape.　Chaiqian (Demolition) explores not only the interactions between these members of China’s “floating population,” but also the fleeting nature of experience for them, as well as for the worksite managers, city dwellers, and the filmmaker himself.
