The "Preface to the Holy Religion of the Wild Goose Pagoda" was established in the fourth year of Yonghui in the Tang Dynasty and was written by Chu Sui of the Tang Dynasty. This stele is most in the style of the Chu family. Its knotted characters are more relaxed than those of Ou and Yu, and there are also many changes in the writing style.
  Reminder:
  Ming Dynasty Sheng Shitai: "Preface to the Holy Teachings of the Tripitaka", two copies of which were handed down from generation to generation. I commented on them and thought that Wang's book was like a dry fox gathering its fur, leaving no trace at all, while Chu's book was like a solitary silkworm spinning its silk, with its articles intact. However, in today's book collection house, there are many inscriptions on Youjun, but only extensions on Zhongshu. The paper and ink on this piece of bamboo slip are excellent, and the original Pu can be preserved. ("Cangrunxuan Stele and Postscript")
  Bao Shichen, Qing Dynasty: Henan's "Holy Religion Preface" is written on the right side of the book. When reading from left to right, the words are facing each other; when reading from right to left, the writings are opposite to each other. Alas! Knowing this can be written in words.
