Normally there is a screen-wall inside the gate so that outsiders cannot see directly into the courtyard and it is also believed to protect the houses from evil spirits. Outside the gate of some large siheyuan, there is a pair of stone lions on each side. Such a residence offers space, comfort and quiet privacy. It is also good for security as well as protection against dust and storms.
