Correction method:
Go straight to the door or intersection or T-junction, and set a' Taishan Shi Gandang' on the left front.
Shi Gandang, also known as Taishan Shi Gandang, is a stone tablet standing on the wall of streets and lanes, especially T-junction and other roads, which is called a fierce position, to ward off evil spirits. The words "Shi Gandang" or "Taishan Shi Gandang" are engraved on the stone tablet, and there are bas-reliefs of the lion's head and the tiger's head on the stone tablet. In fact, Shi Gandang is the most famous mountain to ward off evil spirits.
If the cross section is lower than the road surface, please look for a mirror and hang a red cloth. You can also reverse open the back door after closing the front door. If the gap is large, you can take a ladder upstairs to the road. What is so important is opposition, avoidance and equality.
