Introduction to the mountain gate: Passing through the hanging flower gate tower, the four words "Li Yuan Ming" are hung eye-catching on the round mountain gate. These four words embody Confucius's Confucianism, requiring people to be polite, well-behaved, and An aboveboard person. Writing these four words on the last "pass" before visiting the Buddha shows that later generations also have certain requirements for worshiping the Buddha. It seems to warn those who have done bad things to change their appearance when they visit the Buddha to atone for their sins. Walk out of this door and start a new life.
