呢本書反映咗康有為早期匯集咗古今中外嘅學術思想，係康有為早年嘅重要著作之一。1947年美國斯坦福大學胡佛圖書館將呢本書嘅書稿同《實理公法全書》書稿整成縮微膠卷，後來美國加州大學劉廣京教授將呢兩本書縮微膠卷影印本嘅複制本送畀康有為嘅女康同璧。依家所登嘅各個版本都用梗呢個穚。
This book reflects Kang Youwei's early collection of ancient and modern Chinese and foreign academic thoughts, and is one of Kang Youwei's important works in his early years. In 1947 United States Hoover Library of Stanford University compiled the manuscript of this book and the manuscript of "The Complete Book of Practical Public Law" into microfilm, and United States later, Professor Liu Guangjing of the University of California sent copies of the microfilm photocopies of these two books to Kang Youwei's daughter, Kang Hebi. All the versions that have been published now use this stalk.
