Introduction to the Immortal Stone: There is a protruding peak halfway up the mountain, which looks like an immortal. It is said that the founder Zhang Sanfeng collected medicine here and left his shadow. The ancients called it the "Immortal Stone". And because it stands in front of the mountain gate, it looks like a gatekeeper general. Some people say that this is General Meng Xi guarding his camp, so it is called the immortal gatekeeper or the immortal guide.
