Horse Head Tree Introduction: Legend has it that Xuanzang of the Tang Dynasty passed by the Liusha River on his way to the West to obtain Buddhist scriptures. He went to collect the Sha monk and temporarily tied the little white horse to this tree. Unexpectedly, Tang Xuanzang didn't come back for several days. The little white horse was so hungry that it couldn't break free from the reins. It was so angry that it hit the tree trunk. As a result, its body was caught in the tree trunk, and the horse's head finally broke free.
