Why is Hengshan Mountain called the Taoist activity place of Wanshan ancestor in the north?

Hengshan Mountain has a long history as a place for Taoist activities. Taoism has thirty-six caves and seventy-two blessed places, all of which are places where immortals live and amuse themselves. The fifth cave, Hengshan Cave in Beiyue, which travels 3,000 miles a week, is called Wuxuan Cave, located in Quyang County, Changshan, Hengzhou. Today's damao mountain. The world thinks that the land of heaven is auspicious and full of admiration. Taoist hermits like to live in quiet forests, so they choose places with fairy tales to build temples, which can benefit from the fairy wind and Taoist temple. Since ancient times, Taoist couples have not lived together, and pilgrims come in an endless stream. Therefore, this cave has become a scenic spot in China Xiuhe Mountain.

According to legend, Zhang, one of the eight immortals of ancient Taoism in China, lived in seclusion in Hengshan Mountain, leaving behind many myths and legends.

"Taiping Guangji" records that Zhang "often rides a white donkey, and the number of days is Wan Li, so it overlaps. It is as thick as paper and put in a towel box. If you ride it, it will be covered with water and it will become a donkey. " Xuanzong summoned him to demonstrate the changing skills of the immortal family. Xuanzong was praised as "high-spirited, ambitious" and given the title of "Mr. Xuan Tong", and then returned to Hengshan. On a smooth and steep stone slope in Guolaoling, there are several obvious donkey hoof prints, which are said to have been left by Zhang when riding a donkey to heaven.
