Introduction to Panchi: Panchi is located in front of Taihe Yuanqi Square. It was first built in the Yuan Dynasty and is a semicircular pool. In the ancient ritual system, the study of the emperor was called Piyong, and the study of the princes was called Pan Palace. There are pools in the southeast and southwest of Pan Palace, shaped like half walls, so they are called Panchi. There is a bridge over Panchi, called Panshui Bridge, which was the bridge of the Academy in ancient times.
