After the narrative, "Zizhi Tongjian" has appendices, totaling 186 articles. Among them, there are 102 "Chen Guang Yue" and the remaining 84 commentaries from various schools. Among them, Pei Ziye's commentaries account for 10 and Sima Qian's only one. In terms of the number of chapters, "Tang Ji" occupies the most space (81 volumes), followed by "Han Ji" (60 volumes). Chen Yuan's "Hu Zhu Tongjian Biaowei" said: "The calligraphy of Tongjian is not entirely about praise and criticism, so it is not as strict as the Spring and Autumn Annals. Wen Gongqian did not dare to imitate the Spring and Autumn Annals, but aimed to continue the Zuo Shi Zhuan. When I felt something, I also imitated Zuo's rhetoric "Junzi said" and called it "Chen Guang said" to express it. I wrote it directly according to the actual situation, so that people can evaluate the gains and losses according to the actual situation, as a warning, but it is not certain. From today's point of view, "Chen Guang Yue" is full of feudal colors. Huang Shengxiong summarizes it as "sincerity" and "propriety". The concept of "the principles of etiquette" can be said to run through the core of "Tongjian". Zhang Xu said in "Tongjian Xue": "The meaning of "Spring and Autumn" is that the most important thing is the name, where the name is, and one word cannot be misinterpreted. In the feudal world, this is the guideline. If the name is bad, then the guideline is If it is eliminated, the political power will inevitably collapse. Wen Gong used this incident to signify the decline of the Eastern Zhou Dynasty and the separation of the seven kingdoms, and he also discussed it to see the beginning. "Sima Guang's own thoughts did not transcend the times, so his discussion. Not of much value. For example: Sima Yan was praised by Sima Guang as an "unrivaled virtuous king" because he stayed in mourning for three years. In fact, Sima Yan cannot be compared with Taizong of the Tang Dynasty, Emperor Wu of the Han Dynasty, etc. in Chinese history.
