I admire Sima Qian most. Sima Qian only wrote historical records all his life, and his father, Sima Tan, was Taishiling (equivalent to the post of director of the National Library now). Sima Qian lived a poor life in his hometown in his early years. In the sixth year of Jianyuan, after Dou Taihou's death, Emperor Wu of the Han Dynasty stopped at Huang Lao's words, and was punished by hundreds of people, thus re-launching the respect for Confucianism. This is the famous "ousting a hundred schools of thought and respecting Confucianism alone". In the second year of Yuan Shuo in Han Dynasty, Sima Qian moved to Chang 'an from Ji M, and then moved to Beijing with his family, learning Shangshu from Kong Anguo and Chunqiu from Dong Zhongshu. Then he inherited his father's career and became a Taishiling. In BC 104, Sima Qian presided over the revision of the calendar, and at the same time officially began to write Taishi Gongshu. In the second year of Tian Han (99 BC), Emperor Wu of the Han Dynasty was angered by the "Li Ling incident" and begged Li Ling to surrender to the Xiongnu. Emperor Wu of the Han Dynasty thought he was defending Li Ling, so he arrested Sima Qian and put him in prison. In prison, Sima Qian worked hard to improve himself, endured the unbearable pain of ordinary people and continued to write historical records. After Sima Qian was released from prison, he served as a secretariat official, continued to write books with indignation, and finally completed the Historical Records in 9 1 BC. In 87 BC, Sima Qian died at the age of 58. The cause of Sima Qian's death is still an unsolved mystery because it is not clearly recorded in historical materials. (Most people think that Sima Qian died after Emperor Wu, while others think that Sima Qian died of witchcraft. )
