I found a stone tablet on the door wall of some old houses, with the words "Taishan Stone Gandang" engraved on it. What is it?

It is common for Chinese folk houses to have the words "Taishan Shi Gandang" hanging on them. The purpose is to ward off evil spirits! It originated from a legend. Shi Gandang was an acupuncturist with very good medical skills. His home was in the Mount Tai, so everyone calls him Mount Tai Shi Gandang. This gentleman has never had any airs. No matter who he is or what time it is, he is always available and gives acupuncture for free. What he is particularly good at is treating evil spirits, evil spirits and evil spirits. Regardless of whether it is a vixen who has practiced for thousands of years or has become an immortal through ten thousand years of cultivation, he has possessed the human body. As long as he looks at the right acupoint and delivers a fatal injection, the vixen will die at that time and the patient will be cured immediately. Countless vixens were stabbed to death by him. Therefore, the vixen is afraid of him and hates him.

That night, Shi Gandang was sleeping soundly when he heard someone calling the door. He turned over and got up and opened the door. He saw an old man holding a donkey and said, "Mr. Shi, go quickly. My son is sick. What you said in nonsense may be a vixen." Shi Gandang did not hesitate when he heard this. , took his needle box and got on the donkey and followed the old man.

After walking for about two hours, I don’t know how far I walked, I came to a deep mountain and still no one was there. Shi Gandang asked: "Are you almost home?" The old man said: "We're home, it's your hometown, let's get off the donkey." When Shi Gandang heard this, he said: "It's broken, I was fooled." He had to get off the donkey. The old man said: "You are so bold Shi Gandang. I am here for revenge. How many of my friends have died in your hands. Just wait here. I will kill you at noon. I don't think you can fly anywhere." ." After that, the old man and the donkey disappeared. Shi Gandang stood for a while and thought: "It's impossible to walk. It's dark in the middle of the night. There are mountains all around and there are no roads. It's death anyway. I might as well take a walk." So he groped in the dark and headed northwest. Go. After walking for about two or three miles, I saw a small house with a light inside. He thought there would be someone there if there was light, so he knocked on the door and said, "Come in." Shi Gandang pushed the door open and entered the house, where he saw an old woman sitting spinning cotton. The old woman looked up and said, "Why are you still Mr. Shi? What are you doing here?" Shi Gandang told everything about his arrival. The old woman said: "You have been fooled. This mountain is called Pihu Mountain. Fortunately, you met me. Otherwise, if you really can't survive, come here." The old woman said, taking Shi Gandang's right hand and placing it in his palm. He made a "ten" inside and said, "Hold it tightly and open it when you are in a hurry. Go quickly." This old woman is the old lady of Taishan - Bixia Yuanjun. She came specially to rescue Shi Gandang.

Shi Gandang wandered again and came to the place where he got off the donkey. It was already dawn, and he saw groups of vixens coming from all directions, some with knives, some with guns, and they kept cursing and surrounding Shi Gandang. Shi Gandang sat on a stone, clenching his right hand and motionless. When it was almost noon, there were hundreds or even thousands of vixens around Shi Gandang, big and small, all surrounding him. Shi Gandang stood up and suddenly opened his hands. He heard a thunderbolt on the ground, and the mountains shook. Some of these vixens were killed by the thunderbolt, and some were knocked unconscious. The ones who were not injured ran away.

From then on, these foxes would be so frightened that they would run away as soon as they heard Shi Gandang's name. Later, in order not to be harmed by vixens, people wrote the words "Taishan Shigandang" on the walls of intersections. Everyone should naturally recite it wherever they go, and they will never attract demons.
