After the transformation of the economic structure, China embarked on the road of urbanization. Large areas of the old city were demolished and replaced by residential buildings and commercial streets. In the process of urban renewal, urban villages have always been regarded as an indelible part of the city .Negative space has many problems such as high building density, backward infrastructure, and poor sanitary conditions.

The original urban village was replaced by a middle-class community, and the rising land and housing prices could no longer allow the original residents to return to their previous living places.
