Chongqing is known as the "mountain city", this city with a large terrain, the buildings are also layer by layer, one layer by layer, so it is necessary to use the city land area reasonably. Liziba Light Rail Station reasonably uses the local land, covers a small area, and has a small impact on residents. The light rail turning radius is small, the climbing ability is strong, and the city viewing degree is also very high. Therefore, an observation deck is specially established to provide visitors with a viewing location. This design is very suitable for Chongqing.
