"Preface to the Theory of Breaking Evil" is said to have been written by Yu Shinan, with thirty-six lines in regular script and twenty crosses in each line. There are two types of engravings handed down from generation to generation, which are signed: "Yu Shinan, a member of Prince Zhongshushe, wrote and wrote it" and "Yu Shinan, a member of Prince Zhongshushe, wrote and wrote it in Wujun". They are distinguished by the presence or absence of the word "Wujun". Volume 1 of Zhang Chou's "Authentic Records" of the Ming Dynasty contains: "Yu Yongxing's theory of breaking evil in small regular script. According to this series, "Calligraphy and Painting Fang" has been engraved, but it has been deleted now." It seems that there were still ink traces handed down from that time. This calligraphy has been reprinted and reprinted by many people in later generations, including "Tan Tie", "Baojin Zhai Tie", "Yuyantang Tie", "Dingyun Guan Tie" and other engraved editions, especially the one passed down as the "Yuezhou Shi's Edition" is the best. .



Before the Ming Dynasty, scholars had no doubt that this post was written by Yu Shinan. Volume 18 of "Jin Xie Lin Lang" written by Du Mu in the Ming Dynasty: "The Preface to the Theory of Breaking Evils" on the right was written by Yu Shinan of the Tang Dynasty and combined in small regular script. Shinan's writing is only "Confucius Gallery" "Tangstele" has been published in the world. Although neither Ouyang Gong nor Zhao Mingcheng has seen this article, it is fortunate that I have seen it. "Best Evil Theory" is now published in "Shishi Tibetan Sutra", and there is no time to study it deeply. If Shi Nan Shu , I gave it to my hobby, so I recorded it." Volume 156 of "The Continuation of Yanzhou" by Wang Shizhen of the Ming Dynasty, "Preface to the Theory of Calligraphy Breaking Evil": "Yu Yongxing Shinan's calligraphy is rare, and regular script is especially difficult to obtain. . The smaller one is "Preface to the Theory of Breaking Evil", and the slightly larger one is "Confucius Temple Stele". "Breaking Evil" is extremely capable and almost unparalleled in skill, so it is not possible to be in the second royal family, but it seems that one cannot forget his feelings on the road." Dong Qichang of the Ming Dynasty. Volume 2 of "Rongtai Collection" "Shupin": "Yu Yongxing's official book "Confucius Temple" is popular in the world. ..."Best Evil Theory" is in Tang Dynasty's small regular script, and it is the same as Liu Chengxuan's "Qingjing Jing". 1. Jian Zhiyi Xing Wu Guanglu's family, although he copied and engraved the "Xihongtang Tie", he did not use the method. "Best Evil Theory" occasionally got a Song extension, and I am here."



After the Qing Dynasty, scholars began to question whether this post was written by Yu Shinan. Volume 8 of Yao Nai's "The Complete Works of Xibao For example, You Yanzhi, how can you look at the generation and seek truth through research and verification? I say that your words are definitely correct, but they are also too biased. And as it is said in the world, Yu Yongxing's "Preface to the Theory of Breaking Evil" signed himself as "Prince Zhong" "Shu Sheren", but there is a person from Zhongshe in the crown prince's official position, is there a person from Zhongshushe? Yongxing's father's name is Li, and the word "Xili" is used in the preface. This must be a false assumption made by monks in the Tang Dynasty who had little knowledge. He wants to take self-improvement more seriously than the ears of the world. Si Weng is unable to discern. He has repeatedly studied Yongxing's "Ba Xie Lun". Is this the case for those who discern carefully?... All of this is clearly wrong through textual research, but Si Weng cannot be without mistakes. . However, if you claim to be discerning, you may be gullible and deceive yourself. On the contrary, it is worse than the expert who has nothing to hide."



The Qing Dynasty's "Leng Lu Miscellaneous Identification" Volume 1: "Yu Yongxing's "Preface to the Theory of Poisoning Evils" is the most treasured in the world. Yu Guan, Ye Zhengjun of Kunshan, Yibao's "Inscriptions and Stones" said that the "Preface to the Theory of Popping Evils" says: "Taishi Ling" Fu Yi, whose studies were superficial and very thoughtful, wrote short stories to gain enlightenment based on Ling Ling. The master admired Hou Kun and wrote a volume called "On Destroying Evil". . Now I think it is evil, and Shinan has made peace, so why? Also look at Tongcheng Yao Ji's biography Bibu Nai's "Xibao There are many people who, with their fresh and discerning knowledge, regard falsehood as truth, and this is not the only one who does so."



Luo Zhenyu's "Xue Tang Lei Manuscript·Fa Shu Postscript" No. 16 "Postscript to "Preface to the Theory of Breaking Evil": "Yu Bo Shi wrote "Preface to the Theory of Breaking Evil", Yu thought it was a false pretense. Guan Bo Shi's official title book "Prince Zhong Shushe" "People', when examining "Tang Shu", there is "Prince Zhongshu Ren", so there is no such thing as "Prince Zhongshu Shuren". However, the calligraphy is so exquisite that it cannot be done by a Tang sage, and it is beyond the reach of Song people." Yao Nai et al. Starting from the research of the official title of "Prince Zhongshusheren", scholars have strongly proved that this book cannot be written by Yu Shinan, which is convincing to a certain extent.



According to the signature in the post, this "Preface to the Theory of Destroying Evil" is the preface written by Yu Shinan for Master Fa Lin's "Theory of Destroying Evil". Master Falin (572-640), whose common surname was Chen, was from Yingchuan (now Yuzhou, Henan) in the Tang Dynasty. He became a monk at a young age and was well versed in all scriptures. At the end of the Sui Dynasty, he lived in seclusion in Guigu Cave in Qingxi Mountain. At the beginning of Wudechu, Emperor Gaozu of the Tang Dynasty, he was stationed at Jifa Temple in Chang'an, Xixi. Later, Fu Yi asked for the abolition of Buddhism, and Taoist priest Li Zhongqing and others wrote articles denouncing Buddhism. Master Fa Lin wrote "The Theory of Destroying Evil" and "Lun of Discrimination of Righteousness" to refute them respectively. In the thirteenth year of Zhenguan (639), the Taoist priest Qin Shiying reported that "Bian Zheng Lun" "slandered the emperor". Taizong summoned Fa Lin to Bian Dui and sentenced him to death. Later, he was sentenced to exile in Yizhou. In June of the following year, the master went to Baiyuguan Bodhi Temple and died of illness. The master has a literary mind and is good at conversation. He has written more than 30 volumes of poems and essays. There are biographies in Volume 32 of "Extended Biography of Eminent Monks", Volume 8 of "Kaiyuan Buddhism Records", and there are also three volumes of "Farewell Biography of the Buddhist Protector of the Tang Dynasty" by Yan Tai.



Yu Shinan's "Preface to the Theory of Destroying Evil", also known as "Preface to the Collection of Master Xiangyang Falin", is included in Volume 138 of "Quan Tangwen". His articles can also be found in the "Part Two Biography of the Buddhist Protector Samana Falin of the Tang Dynasty, Volume 2" in the History and Biographies of the Taisho Canon, and in the sixth volume of the Chinese part of the "Chinese Tripitaka", the "Part Two Biographies of the Buddhist Protector Samana Falin of the Tang Dynasty, Volume Two", etc. You can refer to school.
