The most typical symbolic building of the harmony between man and nature in ancient Chinese was Mingtang Piyong. "Mingtang Piyong" is a building, but it contains the meaning of two architectural names. It is one of the highest-level royal ritual buildings in ancient China. Mingtang was a place where ancient emperors issued government orders to accept pilgrimages and sacrifices to the gods of heaven and earth and their ancestors. Piyong is the circular water ditch surrounding the Mingtang. The water is yong (meaning perfection and perfection), and the circular shape is pi (pi is bi, the emperor’s special jade ritual vessel), which symbolizes the perfection of Wang Taoism. Piyong is a university set up by Emperor Zhou. The site is circular, surrounded by a pool, and there is a temporary bridge outside the front door. After the Eastern Han dynasty, there were Pi Yong, as a place to respect Confucianism and perform ceremonies.
