What is the layout of a three-entry courtyard like?

This kind of building has a strict north-south axis. The entrance of the house is mostly arranged in the southeast corner, which is completely in line with the folk custom, because people have a good feeling about the east and south, "Purple energy comes from the east", "longevity than Nanshan Mountain," said. After entering the door, face to face is a shadow wall, the wall is often decorated with exquisite brick carvings, shadow wall in front of more than a few potted flowers, so that the space is alive. Shadow wall in space also plays a role in the axis of turning. From the space art, turning is a subtle technique; but in ancient times, the main intention is to avoid evil spirits. It is said that by turning a few corners, the evil spirits could not enter the house. The shadow wall does not allow people to directly see the situation inside the house, the family does not reveal its wealth, and the family's ugliness should not be publicized. These are the full reflection of traditional Chinese concepts in residential architecture. Into the house, is a small and narrow courtyard. South side of a row of north-facing house, called "inverted seat", which is the servants live in the room. Can also be used for overnight stays, while the others are stacked with sundries. At the north end of the courtyard, there is a stack of walls, and in the center (on the central axis of the house) there is an ornate door called the hanging flower door, and inside the door there is a large courtyard, which is the main courtyard of the "Courtyard". The main courtyard is a green, deep courtyard. The main room in the center of the courtyard is the main house, with the central axis running through it, facing south, the volume is the largest in the whole house, and here lives the head of the house (the eldest). On both sides of the house, there are the east and west ear rooms and the small courtyard. Directly in front of the left and right is the room, that is the place where the younger generation lives. The rooms are small in size and shallow in depth. There are corridors connecting the buildings, so that you don't have to walk on wet roads in rainy days. After the main house, there is a small courtyard, and this is the third entry, a row of houses facing south, called the "cover room", usually the maid's housing, storage, and miscellaneous houses. The entire mansion periphery are generally not open windows, space for the inner closed, more quiet.
