The Chaoyuan Pavilion is close to the old mother hall of the Lushan Mountain. It is the royal Taoist view of the Tang Dynasty that specializes in the Taishang Laojun. The history is large and the two-fold temple that is now only rebuilt. The mountain gate is the spiritual palace and the courtyard is the octagonal main hall. The temple is the "Taishang Xuandu", which shows its historical and religious status.
