Why is it said that "Learning from the same experience" is "The Book of the Emperor"?

Zi Tongzhi Jian is called "The Book of the Emperor" because its content and form are for the emperor to read.

In form, chronological style is more objective than biographical style. Although the official history of ancient China is mainly biographies. Biography also has its own characteristics, that is, it can better record the appearance of an emperor and a general. However, due to different historians in different dynasties, there are some mistakes in the authenticity of biographies themselves. Compared with Sima Qian's factual records, there are many official histories in later generations. Most of them contain the author's own opinions, but in form, chronology records the time, place and people according to the year. Sima Guang, the author of Zi Tong Zhi Jian, can't express much personal feelings in form. In this case, he can provide the emperor with more objective and real feelings, and let him know what the real historical development is like, so as to better govern the country. Therefore, from the formal point of view, the Chronicle of Zi Tongzhi Jian can be called the book of emperors.

As far as content is concerned, what is Purple Tongzhi Sword? In view of the past, is capital governing? A copy. The development of history always has its inevitability and contingency. What is clear in Zi Tongzhi Jian is to break a contingency and emphasize a inevitability. Let emperors of all ages not have illusions about anything. The emperor has lived in the ninth five-year plan for a long time, so naturally he can't be as good as a woman. In this case, the content of "Learning from the Same Resources" made the emperor realize the inevitability and contingency of historical development. Let the emperor be really ruthless, so as to sit firmly in this position. So it is helpful for the emperor to be in power. Therefore, she is also called the book of emperors in content.

To sum up, in form, the chronological style of Zi Tongzhi Jian is called The Book of the Emperor. From the content, the historical inevitability of Zi Tongzhi Jian itself should be called The Book of the Emperor.
