If you want historical materials, the historical books from ancient times to the present include Shangshu, Chunqiu, Shiji (Sima Qian of Han Dynasty), Hanshu (Ban Gu of Han Dynasty), Houhanshu (Southern Song Dynasty), The History of the Three Kingdoms (Chen Jinshou), The Book of Jin (Tang Fang, etc.) and the Song Dynasty.
The Book of Southern Qi (Zixian County, South Liang Xiao), Liang Shu (Don Yao Silian) and Chen Shu (Don Yao Silian).
Shu Wei (Beiqiweishou), Beiqishu (Tang Baiyao), Zhou Shu (Tang Linghu's powder, etc. )
Sui Shu (Don Wei Zhi, etc. ), Southern History (Don li yanshou) and Northern History (Don li yanshou).
Old Tang books (Liu Shao, etc. ) The Book of the New Tang Dynasty (Ouyang Xiu, Song Qi, Song) and History of the Old Five Dynasties (Xue,). )
History of the New Five Dynasties (Song Ouyang Xiu), History of the Song Dynasty (Yuan), etc. ) and Liao History (Yuan et al. )
Jin Shi (yuan, etc. ), Yuan (Lian, etc. ) and Shi Ming (zqq Yu Ting, etc. )
The twenty-four histories, together with the draft of the Qing Dynasty, make the official history more complete. If you want to be relatively true, I suggest reading Historical Records and the History of the Three Kingdoms. By the way, there is "Zi Tong Zhi Jian", which is not true, but it is still very strict when compiling the book. Or look at the research works, there are also many critical views.
Books like Romance of the Three Kingdoms are not real history. It is a novelist who writes history into various stories, and stories and facts often have certain deviations.
