Introduction to the Hunyuan Stone: The Hunyuan Stone is located on the east side of the temple. It is said that when the Jade Emperor Zhang Bairen was in charge of the Three Realms, he often opened the Nantian Gate in order to summon the gods. Later, when the Three Realms were in chaos, the rebels attacked the Nantian Gate in order to defend the Heavenly Gate. One day, a senior monk of the great temple moved a huge stone from Hunyuanding in order to block the Nantian Gate and quell the rebellion. However, he moved the huge stone to the middle of the mountainside of the large temple and finally left it here because of his inability.
