Chunhuamige fatie kaozheng 淳化秘閣法帖考正 "Critical revision of the model calligraphies from the Chunhua Library", also written 淳化祕閣法帖考正, is a critical commentary on the model calligraphies of the Chunhua Hall, the Chunhua fatie 淳化法帖 from the Song period 宋 (960-1279). The critical revision was written during the Qing period 清 (1644-1911) by Wang Shu 王澍 xxx.
The whole book is 12-juan long. Except the core text that comments on the Chunhua fatie, Wang Shu added a short history of model calligraphies, and a chapter on the rules of calligraphy. His book is not the oldest commentary on the Chunhua model calligraphies. The master Mi Fu 米芾 (1051-1107) was the first who wrote a comment on these (Fatie tiba 法帖題跋), with the aim to bring more light into the skill of telling forgeries from real antiques. His study was followed by Huang Bosi's 黃伯思 (1079-1118) Fatie kanwu 法帖刊誤, in which the author pointed at errors in calligraphy books, based on a critical method by analyzing ancent texts. Two more important masters of calligraphic theory were Gu Congyi 顧從義 (1523-1588, author of Getie shiwen kaoyi 閣帖釋文考異) during the Ming period 明 (1368-1644) and He Zhuo 何焯 (1661-1722) from the early Qing period.
