In gardens, buildings and walls or buildings and buildings often leave a narrow space that is not accessible to tourists, and brick walls are sandwiched. This is what gardeners intend to do. Although it is a small place, there are many articles, the purpose of which is to increase the landscape of the garden. For example, in the Yuhuatang area of Yuyuan Garden, from the north of Yuhuatang to the west wall of Deyue Building, there is a pink wall that divides Yulong Scenic Area into two parts. The north is dominated by water appreciation and the south by stone appreciation, with distinct themes and distinctive features. The pink wall and the Deyue Building are not closely linked, but separated by a distance. Stone and trees are planted on an inch of land to form an interesting landscape belt. Standing in Yuhua Hall, it can be seen through the window. This square-inch view becomes an elegant contrast. Although the space here is small, it has its advantages.The path is the embodiment of the smaller scale "separation" in the private gardens in the south of the Yangtze River. A distance between the interface and the interface forms a road. Besides corridors, there are many paths hidden in the natural landscape. The road is formed by leaving a distance between natural rocks, flower beds and vegetation. The mountain formed by stacking stones can form a stone path with ups and downs and twists and turns between rocks. In Liuyuan, Huqiu, Geyuan and many other private gardens in the south of the Yangtze River, it can be seen that the buildings stand on rocks and can pitch up the space of Vientiane. A winding stone path is opened up between the rocks.
