Introduction to Bixia Palace: Bixia Palace was built in the late Tang Dynasty. Li Yuan, the emperor of the Tang Dynasty, recognized Laozi Li Er as his ancestor, and Taoism was highly respected and became the state religion. In 1208, Qiu Chuji was preaching in Qingzhou. At night, he dreamed that Bixia Empress was hidden in the sky, slowly pointing to the southwest. The next day, he ordered Zhao Daojian, Yin Zhiping and his 18 accompanying disciples to search southwest of Qingzhou. They found that Taihe Mountain was full of spiritual energy. The Taoist temple built here is Bixia Palace.
