Throughout ancient Chinese feudal history, the hierarchical system was strictly upheld. This was reflected in the patterns, colors, decorations, and proportions of architectural structures, which were all regulated according to the social status of each family. For example, except for temples, no building was allowed to be taller or larger than the emperor’s palace. In certain dynasties, commoners were forbidden from using auspicious and powerful motifs such as dragons or phoenixes, as well as noble colors like red and yellow.

 

Additionally, the arrangement of rooms was also determined by hierarchy based on function and status. The main halls were placed at the center of the complex, with their entrances facing forward. Auxiliary rooms were arranged symmetrically on the left and right sides, surrounding the main building. Younger family members resided in the side rooms, while kitchens and servants' quarters were positioned at the rear.
