The building has an obvious main axis, which passes through the middle gate, front yard and second gate (or hall) to reach a longitudinal main courtyard. The front is the hall facing south, as a place to entertain guests or hold banquets; The building is on the east and west sides; Behind the hall is a horizontal backyard, which may be the owner's residence. The whole house is centered on the triple courtyard from the gate to the backyard, and a series of affiliated courtyards with different shapes and sizes are arranged around, with a total of at least 20 courtyards. The overall layout is roughly balanced, but it is not absolutely symmetrical. According to different functions, the space is divided into several courtyards, and there are strip or square buildings in the courtyards. Trees and pavilions are planted in some courtyards, indicating that there is a garden part for sightseeing in the house. There is a five-story watchtower on the right behind the house, and the roof is a sentry box protruding from all sides. Flags are hung high on the pavilion, and drums are built in the pavilion, which are used to call the police when the shift is over, indicating that the watchtower is defensive.
The house is built on a rammed earth foundation reinforced with a wooden frame, and the wall may be a rammed earth wall with a wooden skeleton. The roof has two forms: hanging mountain and temple, and the roof is tube tile.
As can be seen from this picture, Sanhe Courtyard and Siheyuan were widely used in China until the end of Han Dynasty, and they were used as basic units to form houses with multi-axis or multi-axis courtyards, with a homestead attached. Only in the Han Dynasty, for more functional considerations, the plane layout of large-sized houses was more flexible than later generations.
