When I was a child, I dreamed of a carefree neighborhood in which everyone realized the importance of “cleanliness”. The building is closely integrated with plants, with saplings poking out of the Windows and towering trees growing out of the chimney. Small animals also coexist with people in the block, and people use natural plants and pollution-free products. People are no longer isolated people, and the modern streets where people live are integrated into the clean ecological circle. People, architecture and nature live together, forming a clean cycle.
