Introduction to the Cave: In the front hall of the cave, 15 meters away from the cave entrance, there is a slightly chiselled fan-shaped plane on the rock wall. The stone inscription of the fourth year of Emperor Taiping of the Northern Wei Dynasty is engraved here. The blessing text is in regular script with Chinese characters in the Wei stele style. The official meaning still exists, it is simple and vigorous, and clear and defensible. This is the "original archive" preserved more than 1,500 years ago and is a precious historical relic of our country. Fortunately, the original has been sealed and protected, and all you can see now is the imitation text.
