孙晓云认为:“只有当汉字书写及造型规则完成时,才可能有评判,有理论。所以,书法发展至东汉,汉字演变停止发展时,方出现完整的书法理论,亦是必然。”作为现存最早的书论长篇,就是东汉光和年间(178-183)赵壹的《非草书》,难不成就是应运而生。“非草书”之“非”当然是非难、非议之意才妥贴。 Sun Xiaoyun thinks: “Only when the Chinese writing and modeling rules are completed can there be judgments and theories. Therefore, when the development of calligraphy progresses to the Eastern Han Dynasty and the evolution of Chinese characters stops developing, it is inevitable that a complete theory of calligraphy will emerge.” “ The earliest extant book theory is the ”non-cursive book“ by Zhao Yi of the Eastern Han Dynasty (178-183), and the most difficult thing is to emerge as the times require. ”Non-cursive “ of ”non " of course, blame, insincere meaning to properly paste.
