At the Chaoyuanguan Site in Jiangjin District of Chongqing City, there are five extant niches of statues in the Sanqingdian grottoes. With clear subject, these statues contain the Three Pristme Ones (三清), Confucius and Zhuangzi (庄子), Shakyamuni and Yinzi (尹子), the Five Sacred Emperors of the Five Sacred Mountains (五岳五天圣帝), and the Five Elders Deities (五老五炁天君). Based on the subjects, styles, architectural age of this site and inscriptions, these statues are dated to the Qing Dynasty. They serve as a reliable reference for identifying the subjects and dating statues in the Sichuan-Chongqing region during the Qing era. They also reflect the spread of the Complete Perfection Tradition (Quanzhen Dao 全真道), Dragon Gate Sect (Longmen Pai 龙门派) in the southwestern part of China, providing new material for studying the integration of the three major religions—Taoism, Buddhism, and Confucianism—during the Ming and Qing dynasties.
