How do celebrities in past dynasties evaluate Cai Jing's calligraphy art

Cai Jing's calligraphy art is charming, vigorous, cheerful and calm, which can reflect the aesthetic taste of calligraphy in Song Dynasty. Therefore, it enjoyed a high reputation at that time, and many people studied its books in the government and the public. Yuan Tao chiayi's "Book History Society" once quoted critics at that time as saying; "Its strict and informal, is nothing more than rules. Books are like swords, and they are discussed in the temple; Running script is like a noble son, full of enthusiasm and brilliance; The big characters are the best in the world, and there are few horses. " It can reflect Cai Jing's position in calligraphy art at that time. At that time, people often used the words "peerless" and "unparalleled" when talking about his calligraphy. Even the arrogant Mifei once said that his calligraphy was not as good as Cai Jing's. It is said that once Cai Jing was chatting with Mi Fei, Cai Jing asked Mi Fei, "Whose handwriting is the best today?" Mi Fei replied: "After Liu Gongquan in the late Tang Dynasty, you and your brother Cai Bian have to be counted." Cai Jing asked, "What next?" Miffy said, "Of course it's me." Existing books include Poems in Caotang, Fu Jie Post and Gong Shi Post.
