We introduced the concept of the "lungs of the city" to transform the community under the elevated roads into the city's lungs, purifying the air. In this design, alveoli represent residential units, filling the community with various functions and areas, from housing to public facilities. Capillaries symbolize the internal transportation routes, tightly connecting each alveolus to ensure the flow of people and air, similar to the oxygenation process in the human body.
