Introduction to the Buddhist Hall: The Buddhist Hall was called Fengxian Hall in history. It was the place where Puyi worshiped his ancestors, gods and Buddhas. In 1934, Puyi moved the interesting tablets and portraits of the ancestors of the Qing Dynasty to the back of the newly built Fengxian Hall in Huaiyuan Building, and it became a Buddhist hall dedicated only to gods and Buddhas.
