The origin of the title of Zi Tong Zhi Jian is that Song Shenzong thought that the book was endowed with the title of "In view of the past, it has the resources to govern Tao". It can be seen that the name of Zi Tong Zhi Jian is not only the conscious expression of historians' management of history, but also the conscious expression of feudal emperors' use of history to serve politics.

Zi Tong Zhi Jian is rich in historical materials. Besides Seventeen History, there are hundreds of miscellaneous historical books. The narratives in books are often written in several materials. In those years, when there are differences in deeds, all of them are added to the textual research, and the reasons as appropriate are indicated, which is regarded as "textual research". Tongjian has high historical value, especially in Sui, Tang and Five Dynasties.

After Zi Tong Zhi Jian was written, in Yuanfeng eight years, Fan Zuyu, Sima Kang, Huang Tingjian and Zhang Shunmin were ordered to revise it again. After the revision in the first year of Yuan You (1086), it was sent to Hangzhou for engraving and published in the seventh year of Yuanyou. Now, Yuan Youben is out of sight. In the second year of Emperor Gaozong Shaoxing in the Southern Song Dynasty (1 132), Yuyao reprinted it, which is also incomplete. According to the original edition reprinted by Hooke family in Qing Dynasty, Zhonghua Book Company corrected punctuation and republished it.
