The walls and floors separate buildings and present a horizontal streamline state. There are two ways to stack rockeries - One is the isolation of Taihu stone to get the aesthetic feeling of stone appreciation; the other is overlapping the rockery along the wall, as to integrate the rockery with the external wall of the building, so that visitors would get a dreamlike feeling of nirvana in space and time. The water falling from the rockery and the scattered clouds make the building and the landscape perfectly integrated to produce an aura feeling.
