Introduction to the building outside the building: The building outside the building is located in the southeast of Daguan Tower, surrounded by water and connected by willow embankments. It faces the Daguan Tower across the Three Pools and Yinyue Lake. The main building outside the building is shaped like a painting boat, three stories high, with a green glazed mountain rolling ridge roof. There are stone railings attached to the horizontal bridge, an octagonal pavilion, a square waterside pavilion, rockery stacked stones, connected flower beds, winding paths, and a three-hole stone bridge across the west. Follow the willow embankment to the West Garden.
