Introduction to the Garden: The inner courtyard is rectangular, and the courtyard is spacious, about twice as large as the outer courtyard. The upper room is symmetrical to the south room, and there are ten, nine, or eight wing rooms in the east and west. For example, when the upper room and the south room each have eight rooms, they are divided into side courtyards according to the pattern of five to three and never violate the rules of "squareness" and "level", which fully demonstrates the momentum of a famous family. However, its ancillary buildings fully demonstrate the "elegantness" of southern garden architecture, making the "square" permeated with "beauty".
