The 'contested development' is the theme of the study area of Chongqing and Chengdu in phase two, and the gap, separation and disharmony of the two areas between the commercial area of shopping centre and the residential-use area is one of the issues that emerged in the spatial development process. The prosperity of the commercial area contrasts sharply with the 'backwardness' of the old residential area, which create two different spatial images. Therefore, breaking the 'boundary' and reusing the street space is an opportunity to promote the connection of the two areas but also a way to create a harmony environment for residents.
