As a royal palace in China's Ming and Qing dynasties, the Forbidden City did not have special toilet facilities in ancient times. People at that time took some clever ways to solve the toilet problem.
First of all, there are some sandwich walls and compartments inside the Forbidden City that are used as toilets, such as the east and west walls inside the Qianqing Gate, and the "West Mao" of the Cining Palace. These sandwich walls and compartments were used as toilets, providing convenience for members of the royal family and court personnel.
Secondly, there is also a facility called dry toilet inside the Forbidden City. Dry toilets are made by loading manure directly into a dug pit and then cleaning the pit regularly. Although this method did not have a flushing function, it was used to solve the toilet problem at the time.
In addition, the planning of the interior of the Forbidden City also took into account the need for toilets. In the concept of the ancients, the basic plan of the capital city should correspond to the stars in the sky to confirm the legitimacy of the feudal royal rule. Because the residence of the Heavenly Emperor is called Ziwei Palace, the palace where the emperor, who calls himself the "Son of Heaven", lives is called "Ziwei, Ziwei, Zigong" and so on. Ordinary people could not enter the imperial palace, so the Forbidden City, as a royal palace, was also known as the "Forbidden City".
In general, although the Forbidden City did not have special toilet facilities in ancient times, the ancients solved the toilet needs of tens of thousands of people by sandwiching walls, compartments and dry toilets, as well as reasonable planning and layout.
