Some compounds have two or more groups of Yi ke yin, that is, two or more courtyards.
The entrance to the compound is in the south elevation with a screen wall standing behind it. This screen wall is important as it is a reflection of Chinese culture and aesthetics. Firstly, it ensures the privacy of those dwelling behind it. Secondly, it has a psychological effect on a visitor. Thirdly, according to folklore the screen wall protects against bad luck. Fourthly, as the Chinese people are naturally reserved, the screen wall protects the courtyard from prying eyes. This allows the occupants to live their lives unobserved by the passerby. Screen walls are seldom plain and are decorated with auspicious patterns or characters, adding a dignity and charm to the stately compound.
Close by the Flower and Bird Market, you can find such old houses. Take a cup of Pu'er tea, in the peaceful surroundings of the courtyard and you will have a deeper understanding of the city and its culture.
