Sima Qian, a great historian in the history of China. When Sima Qian devoted himself to writing Historical Records, he encountered unexpected trouble-Liling incident. His outspoken remarks angered Emperor Wu of the Han Dynasty, who thought he was defending Li Ling, belittled Li Guangli, the younger brother of Li Furen, who returned from the failed expedition, and ordered Sima Qian to be put in prison. Du Zhou, a cruel prison official, tortured Sima Qian, who endured all kinds of cruel physical and mental torture. He never gave in and pleaded not guilty. Soon, it was rumored that Li Ling led Xiongnu soldiers to attack the Han Dynasty. Emperor Wu of the Han Dynasty believed it and hastily killed Li Ling's mother, wife and son. Sima Qian was also sentenced to death for this incident. Because Sima Qian's official was poor and unable to pay for atonement, corruption not only cruelly destroyed people's body and spirit, but also greatly insulted their personality. Sima Qian, like ordinary people, thought of death, but later he thought of Confucius, Qu Yuan, Zuo Qiuming and Sun Bin, and their humiliation and impressive achievements. Sima Qian suddenly felt full of strength, and he resolutely chose corruption. In a letter to his good friend Ren An, he expressed his deep feelings after being punished, and mentioned his intention and determination to write Historical Records. In this famous letter, Sima Qian integrated Mount Tai into the famous sentence of the ages: "People are inherently mortal, either heavier than Mount Tai or lighter than a feather."

Explanation: People should die, but the meaning of death is different. Some people die heavier than Mount Tai, and some people die lighter than the feathers of Hongyan. That is, people should die a fair death, which is valuable.
