Historical Records, formerly known as Taishi Gongshu, was written by Sima Qian, a long history writer, and was born in Hancheng County, Shaanxi Province. Born in BC 145, I said BC 135. His father, Sima Tan, is knowledgeable and once served as Taishiling. He has always been interested in writing "world history", but he failed to do so. Sima Qian was strictly educated by his father since childhood. After his father's death, he succeeded Taishiling and inherited his father's will, and began to write Historical Records in 104 BC. Five years later, Li Ling failed to fight against the Huns and surrendered. Sima Qian was sentenced by the judge for defending Li Ling, and suffered humiliation and indifference. However, he did not give up the compilation of Historical Records, and finally basically completed this work in 9 1 BC, realizing the wishes of two generations of his parents.
