Multi-viewpoint, multi-space and continuous change combined flow space reflects the uncertainty of spatial organization. Buildings and courtyards are nested layer upon layer to form complex streamline. During the tour, visitors can feel that different intensity and types of space are continuously interwoven and penetrating, and never go back. This type of space is quieter and suitable for relatively private functional rooms, and the yard scale is not suitable for short-range sketches. For example, in the eastern part of Liuyuan, there are a series of high and low buildings, such as my reading office, yi feng Xuan, Shilin small courtyard, and he suo, which enclose large and small courtyard spaces with curved corridors. As can be seen from the topology diagram, irregular courtyards are scattered among them, which are integrated by the buildings and set up layer by layer to form a space group with strong privacy and diversified layout.
