In June 2007, Cui found a niche at the top of Gaxian Cave, which is an early design form of the Giant Buddha Cave Temple. Then it was found that turning left at 90 meters inside the cave began with manual excavation, with a huge scale of 50 meters long, 8 to 13 meters wide and 8 to 12 meters high. The side wall of the hole is smooth from the main hole, and the left turn is layered, angular and mottled. At the middle of the hole, more than one meter deep, two pairs of small holes were dug on the left and right. The direction of the main cave is northeast and southwest, and after turning left, it is the meridian direction facing north and south. According to the huge amount of work, design form, unfinished characteristics of the project, cultural characteristics and historical events, it is proved that the northern Wei royal family did it when they worshipped their ancestors in 443 AD. On September 25th, 2009, Wen Yucheng, a grotto researcher, made a field trip and confirmed Cui's discovery and research. On the west side of the main cave, about 15m away from the entrance of the cave, the stone wall is printed with "Zhu Wen", with the line *** 19 and the word 20 1. The font size is different, and the calligraphy style is between Li and He. Calligraphy is Gu Zhuo, with vigorous brushwork. The content is a congratulatory message carved by the third generation emperor of the Northern Wei Dynasty, Tuoba Tao, when he sent Li Chang, assistant minister of Chinese Department, to this birthplace for sacrifice in the fourth year of Taiping Zhenjun (443), which is basically consistent with the records in Shu Wei. Stone inscriptions are important relics of ancient ethnic minorities, with exact dates and literature records. In the black clay sand layer 0.8 meters deep from the surface, many pieces of hand-mixed taupe pottery, as well as stone arrowheads and bone arrowheads, have been unearthed, and their characteristics are similar to those unearthed in the Xianbei remains in Zhalainuoer. Broken stone tools were unearthed in the yellow sand layer 1.3 meters below the surface, indicating that there may be earlier cultural relics here.
In order to protect the stone room, the cultural relics department installed fences and iron gates in front of the stone wall engraved with congratulations, and built drainage ditches and protective railings at the entrance.
In July 20 13, clear stone carvings suspected to be in the early Northern Wei Dynasty were discovered again. The full text of the message is as follows:
"Wei Taiping has been a true gentleman for four years, but he is still young. On July 25th, the Emperor of Heaven ordered me to shoot six treasury officials, including Li Chang and Fu Que, assistant ministers of Zhongshu, and sacrifice them with their feet, one yuan of martial arts and fat. Only then did I dare to tell the Emperor that I helped my ancestors at the beginning and lived there. After 100 million years, Yu moved to the south. How happy you should be living in the Central Plains. Only ancestors and fathers, and expand the quartet. After the celebration, it extended to people, expounded the mysterious wind and added the structure of the worship hall. It is a fierce sword, awesome and barren. You forgot your distance, and you came to the king with a bow. I was there when I first heard about the old market. I looked up at the corner with my chest out. The king's prosperity stems from his ancestors. Melon claws are endless, but only a few moments. Shane, push the sky, the children and grandchildren are full, and the blessings will last forever. Presenter: Di Tian, Di Hou Di.
The ancestors of the emperor can match cold, and the emperor can match first.
Shang Xiang!
Dong Zuoshuai made him read the chisel.
This message eulogizes his ancestors in the tone of the Northern Wei Emperor and prays for their blessing.
