In the courtyard, there are copper tripod, imperial stele pavilion, copper Sumeru Mountain, Mani pole and the main hall of Yonghegong. The main hall was originally called Yin'an Hall. It was originally the place where Prince Yong met with civil and military officials. In the north of the hall, there are three bronze statues of the third Buddha nearly two meters high. In the northeast corner of the main hall, there is a bronze statue of Avalokitesvara, and in the northwest corner, there is a bronze statue of Maitreya.
