Handan Chun, a calligrapher from the Wei Dynasty during the Three Kingdoms period. The courtesy name is Zishu, a native of Yangzhai, Yingchuan (now Yuzhou, Henan). When the official arrives, the matter is in progress. Gongshu can be used in all styles. Yuan Ang's "Book Review" said that his book: "If you follow the rules, the square and circle will be perfect." Wei Heng's "Four Body Scripts" of the Western Jin Dynasty records that his seal calligrapher Fa Cao Xi, his regular script is based on Fa Wang Cizhong, and he is good at writing small characters. He also believes that Cai is famous for his jokes and stories that mock stupidity, some of which have strong social significance. The book has been lost, and only 29 pieces remain. Some later joke books, the earliest joke collection in my country, were all influenced by the book "Laughing Forest". He was honored as the founder of "Laughing Forest" by later generations. Handan Chun was famous for being good at seal script. The preface to the ancient text of Wei Heng's "Four Body Scripts" says: "Since the Qin Dynasty, seal scripts have been used and ancient scriptures burned, and the ancient writings have become extinct. During the reign of Emperor Wu of the Han Dynasty, King Gong of Lu destroyed Confucius's house and obtained the Shangshu, the Spring and Autumn Annals, and the Analects of Confucius. "The Book of Filial Piety" was no longer known to exist in ancient times, so it was called Kedoushu. It was a secret collection of the Han Dynasty. It is hoped that the ancient text was transmitted in the early Wei Dynasty and came from Chun, Handan." Handan Chun's calligraphy achievements were great. "Wei Lue" said that he was "good at Cang", "Ya", Chong, Zhuan and Xu's calligraphy." It's a pity that his ink marks have long since disappeared. He is erudite and talented, proficient in exegesis, and good at writing Chongzhuan and Bafen official script. He was highly regarded by Cao Cao. In Wei Huangchu (222), the official was a doctor, and he was given the title of Shizhong. Because of his exquisite workmanship in his Tou Hu Fu, he was rewarded by Emperor Wen of Wei. He wrote 3 volumes of "Laughing Forest", which were increased to 10 volumes by the Song Dynasty people. The original book is no longer available, but it has a certain status in the history of Chinese literature.
