Introduction to Shangqing Palace: The third largest palace is the palace of Shangqing Zhenren, the teacher supported by Tianshi Xuansu. Shangqing's surname was Baicheng, his given name was Yansheng, and his courtesy name was Zhigao. According to legend, he was a native of the Zhonghuang Dynasty. Because he was born under Berlin, his surname was Baicheng. His mother was exposed to the Japanese and became pregnant, so she was named Yansheng. When he was 9 years old, he began to study Taoism and learned "The Record of Fetal Essence", "The Inner Diameter of the Fetus", "The Method of Nourishing the Mind" and "The Essentials of Interpretation of Sutras". Later, he learned "The Tao of Xuanfang", "Tools of the Three True Realms" and "Dadong Zhenjing" from the Jade Emperor Erdaojun, and thus became the Supreme Master. There are Qiankun Stone, Vicissitudes of Life, Dragon Column, Shangqing Zhenren Dharma Statue, Yingxian Screen, Huiguangtai, Xunzhen Road, Laurel Cliff, Tongtian Gate and Optimus Prime. Each scenic spot has a magical legend.
