Under the coherent function of the road network, each scenic spot and landscape node in the park will lay out the scenic spots in a hierarchical and rhythmic way, so as to fully show the beauty of the garden art. Every twists and turns of the urban park road network, or yang, are finally determined by the designer after repeated deliberation. The road network throughout the park guides visitors to the best viewing location of each scenic spot according to the design intent, route and angle. Generally speaking, the function of the garden road is to organize tourists to guide it to all scenic spots in the park, and set up landscape nodes along the garden road itself, and organize tourists to rest, entertain and view。
