The Records are the Western Jin historian Chen Shou’s work, and the core of what this site calls history. They take Cao Wei’s calendar as primary and still give books to Liu Bei and Sun Quan. The prose is tight. Most of the novel’s speeches and inner thoughts are simply not there.
In the Liu-Song period Pei Songzhi was ordered to comment. He quotes histories, separate biographies, and anecdotes from the late Han on, sets variants side by side, and sometimes says plainly that a story will not do. The rejection of the empty fort, Sun Quan’s boat evening under arrows, and Jiang Gan’s visit survive because of those notes. A quotation in Pei is not automatically Chen Shou’s judgment. Entries here distinguish the text from the notes.
The Records have no tables or treatises. Geography and offices need the histories before and after. They are still the first book against which to check the novel.
