Why is there a yard in the middle of No.9 Beijing Gongyuan?

The reason why No.9 Palace Garden has a courtyard in the middle is because the layout of "quadrangle" is often adopted in ancient Chinese architectural design, that is, there is a courtyard around it. There is usually a patio in the yard, which is called court in the building. The function of courtyard is ventilation and lighting, and it can also beautify the environment and increase indoor and outdoor air circulation.

Beijing Gongyuan No.9 was originally an imperial examination room in Ming and Qing Dynasties, which was an important cultural place at that time. Its architecture follows the traditional architectural planning of China, adopts the layout of quadrangles in design, and has a courtyard in its center, which can facilitate the ventilation, lighting and rest of candidates and create a more pleasant quasi-examination room environment.
