The courtyard layout of ancient Chinese houses actually has a lot of content. The courtyard layouts of different dynasties and different classes and ethnic groups in the same dynasty are also different. Some of the differences are "statutory". For example, private residences cannot be higher than government offices, and any single-story building cannot be higher than the imperial palace, etc. Taking the layout of the Han courtyard as an example, over thousands of years of development, three basic rules of courtyard layout have been preserved and passed down. First, the main room faces south, second, the wing room is lower than the main room, and third, the layout inside and outside the courtyard pays attention to "Feng Shui". ". Let’s talk about the first point first. Whether it is a royal palace, an official’s residence, a wealthy man’s house or an ordinary residence, due to the objective influence of the northern hemisphere sun in the south, the main rooms are facing south. In fact, it is for the sake of good lighting. This has been true since the primitive society period. , has been formed; and the second point is that in the layout of the ancient Han courtyard, great emphasis was placed on the distinction between "primary and secondary". The entire courtyard may be surrounded by rooms, but the east room, west room, and south room must be lower than the main room. , this point has a long history and can be traced back to the early slave society; the third one has the greatest influence on modern residential courtyards. Ancient Chinese courtyards began to pay attention to "Feng Shui" around the time before the Qin Dynasty, first of all, it was the royal palace, After that, ordinary people gradually followed suit. By the Han Dynasty, palace construction was completely based on the "Feng Shui taboos". By the end of the Han Dynasty, the people also completely followed it. At this time, the standard square courtyard was the characteristic of Chinese courtyards. Later, after nearly two thousand years of development and the continuous integration of some architectural styles of ethnic minorities who went south, by the Qing Dynasty, the standard courtyard house was fully mature.
