In addition, Sima Guang's Zi Tong Zhi Jian also records the Three Kingdoms in detail, but there are private goods in Sima Guang's book, and some historical materials allude to the reform, which needs to be considered.
If you buy the Three Kingdoms with Pei Zhu, you don't need other historical materials: Pei Zhu supplemented many rumors that Chen Shou refused to adopt. Because Chen Shou's choice of historical materials is too strict, Pei's notes have certain historical value-but Pei's notes are too loose and need to be read carefully.
Without Pei's annotation, you can refer to the following books: Miscellaneous Notes of the Book of Changes, Spring and Autumn Annals by Wei, Heroes by Wang Shen, Huayang National Records by Chang Qu, Xi Chi's Spring and Autumn Annals of Han and Jin Dynasties, Xiangyang Ji, Du Wei Fu by Zuo Si, Wei Lue by Yu Qian and Jiang Lue by Yu Pu. These history books are part of the important sources of the History of the Three Kingdoms and Pei's notes, but they are also mixed with many incredible things, some of which are disdainful of Pei Songzhi, not to mention Chen Shou, and even more gain and loss when read.
In addition, modern people also have books worthy of reference, such as Tao's "History of the Three Kingdoms, Food Record" and "History of the Three Kingdoms, War Book". So we don't have to stick to the ancients.
