Guo Quan was born in the early Tang Dynasty (seventh century) and is unknown. Zhan Jingfeng of the Ming Dynasty mentioned in "Dongtu Xuanlan": "In the Tang Zhenguan period, the Jing Shengguo interpretation was written with the word "Xu" on the top of the finger, and the "Law of Shanjian" was written on hard yellow paper." 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.
Most of the scriptures written by people in the Tang Dynasty did not include famous names. Some of them had famous names but were not celebrities. 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". The scriptures in this volume are neat and tidy, with even structure and strong stipples, flexible and skillful brushwork, and appropriate weight. The whole article is written in one go, with superb attainments.
