By investigating negative social character status in urban infrastructures, I hope to provide a series of platforms to guide people reexamine urban space without sense of presence and comprehend inherent value of urban space. 

Based on the redefinition on pedestrianism, I regard negative space as the landscape node and selects three nodes in the urban pedestrian route, including well lid, garbage station and pedestrian overcrossing. By combining with different interaction, i intervene in the space and brings the brand-new viewing experience to common people.
