Introduction to Yuquan: Originates from the main peak of Huashan Mountain. In ancient times, water gushes out of Yuquan courtyard. Legend has it that Princess Jinxian, the younger sister of Emperor Xuanzong of the Tang Dynasty, was dressing up in a well when she was practicing in Huashan Mountain. She accidentally dropped a gold hairpin into the well. The hairpin then flowed out of Yuquan Courtyard, so Yun Yujing was connected to the stream in the valley.
