舊題司空圖《二十四詩品》，現已考知出自《詩家一指》。《詩家一指》另有一較早版本，名《虞侍書詩法》。本文將《虞侍書詩法》與《詩家一指》仔細對校，從文字以至全文結構，均可看出，《虞侍書詩法》全書結構完整、文字整鍊，其所持理論前後呼應，乃出自一人手筆，《二十四品》為其中一環。據此即可證明，《二十四品》絕非司空圖所作。

According to the recent study, it is sure that the so-called Ci-Kun Tu's Twenty-Four Pieces of Poetical Criticism(二十四詩品) comes from Shi Gia Yi Zhi(詩家一指). There is an earlier version of Shi Gia Yi Zhi, which is called Yu Ci Shu Shi Fa(虞侍書詩法). In this paper, by comparison in detail between Yu Ci Shu Shi Fa and Shi Gia Yi Zhi, we can see that the text of Yu Ci Shu Shi Fa is completed by one anonymous author because it is an concise and well-theorized work, and that the text of Twenty-Four Pieces of Poetical Criticism belongs to merely one part of Yu Ci Shu Shi Fa. By the evidence, I think that Ci-Kun Tu is absolutely not the author of Twenty-Four Pieces of Poetical Criticism.
