The version of "Warring States Policy" roughly has two systems. In the early years of the Southern Song Dynasty, Yao Hong of Yanchuan (now Shengxian County, Zhejiang Province) edited and annotated this book with a cautious attitude and loyalty to the original work. The book was completed in Bingyin, Shaoxing (1146), and soon a printed version was available. This version was reprinted by Huang Pilie in the Qing Dynasty and included in the Shiliju Series. It has been widely circulated and is now commonly known as the Yao version. It includes the remaining annotations by Gao Yu of the Eastern Han Dynasty and the continued annotations by Yao Hong. At the same time as Yao Hong, Bao Biao of Jinyun (now Jinyun, Zhejiang) also wrote annotations for "Warring States Policy". Bao changed the original text and rearranged it, which was ridiculed by many people in later generations. In the Yuan Dynasty, Wu Shidao wrote annotations for "Warring States Policy". He corrected errors in Bao's annotations and filled in the gaps, clearing up doubts and stagnating information, which was very convenient for readers. The first editor of "Sibu Congkan" included a photocopy of Wu Shu's engraving from the 15th year of Yuan Zhizheng (1355), and many other re-engraved editions have been circulated. This version is now commonly known as the Bao Wu version. Since then, many Chinese and foreign scholars have studied "Warring States Policy", either short essays or huge essays, and each has gained something. Recent scholars Jin Zhengwei has "Supplementary Commentary on Warring States Policy", Zhu Zugeng has "Collection and Commentary on Warring States Policy", and Miao Wenyuan has "New School Notes on Warring States Policy".
