This kind of scripture written by him is the only one seen today. . At the end of the volume of "Shan Jian Lv", Xu*, a Ming Dynasty scholar, mentioned in his postscript that the "Lanting Hu Preface" kept in his home was a copy of Chu people's Guo Quan.

Therefore, calligraphers did not pay enough attention to them in the past. In fact, due to the emphasis on calligraphy in the Tang Dynasty, especially in the middle and prosperous Tang Dynasty, the level of calligraphy for writing scriptures was generally very high. "The Law of Good Views" describes Sakyamuni's propagation of Buddhism. At the end of the volume, it is written "Volume of Good Views" at the top, and at the bottom it is signed "Written by the State on December 10, the 22nd year of Zhenguan".
