Pei Songzhi

Pei Songzhi (372–451^[2]), courtesy name Shiqi, was a Chinese historian and politician who lived in the late Eastern Jin dynasty and the Liu Song dynasty. His ancestral home was in Wenxi County, Shanxi, but he moved to the Jiangnan region later. He is best known for making annotations to the historical text Records of the Three Kingdoms (Sanguozhi) written by Chen Shou in the third century, providing additional details omitted from the original work. His commentary, completed in 429, became integral to later editions of the Sanguozhi, making the joint work three times as long as the original.^[3] His son, Pei Yin (裴駰), and great-grandson Pei Ziye (裴子野), were also well-known historians.
