The main feature is that green space, houses and pedestrian walkways are organically arranged together, the road layout is arc-shaped, people and vehicles are separated, and houses with low building density are arranged in groups to form a pocket shape. Super buildings prevent motor vehicles from crossing the road. Main roads, branch roads and end roads are classified according to their functions.
