Longevity Baxian Temple, also known as Baxian Temple, is located in Changle Square, Dongguan, Xi'an City. The Eight Immortals Palace was built on the site of the original Xingqing Palace in the Tang Dynasty in the Song Dynasty, and the existing buildings were basically built in the Qing Dynasty. According to legend, this is the place where Lu Dongbin was enlightened by Han Zhongli's "a pillow of yellow beams". In 1900, the Eight-Power Allied Forces invaded Beijing, and the Empress Dowager Cixi and Emperor Guangxu fled to Xi'an for refuge. They once awarded 1,000 taels of silver and ordered Li Zongyang, the head of the Eight Immortals Nunnery, to build the archway, and awarded the temple's title "Building the Eight Immortals Palace for Longevity", hence the name of the Eight Immortals Palace. . The Eight Immortals Palace can be divided into three parts. Except for the mountain gate, archway, Zhaobi, and Bell and Drum Tower, the first part has 5 halls; the remaining part can be divided into two parts, the front and the rear, and the rear hall is dedicated to the statues of the Eight Immortals. The statues have vivid expressions, fluttering robes, and each statue has its own characteristics: Zhang Guolao's humor, Lv Dongbin's justice, Han Xiangzi's charm and so on. The third part is the main hall. On the door of the hall, there is a plaque with "Yuqing Zhidao" written by Emperor Guangxu himself. On both sides of the main hall are east and west courtyards. In the east, there are Lu Zu Hall and Yaowang Hall, dedicated to Lu Dongbin and Sun Simiao respectively, and the west courtyard is the residence of Taoist priests in the nunnery.
