Introduction to the ruins of the Palace of Eternal Life: The ruins of the Palace of Eternal Life, also called Jiling Terrace, are located to the east of Wanzhao Pavilion and were one of the main buildings of the Huaqing Palace in the Tang Dynasty. It was originally a place where the royal palace and ministers fasted and bathed before going to Chaoyuan Pavilion to worship. Later, it became a place for Emperor Ming of the Tang Dynasty and Concubine Yang to relax and escape the summer.
