What did Sima Qian insist on in the Han Dynasty?

You can read Bao Ren An Shu by Sima Qian and feel Sima Qian's mentality at that time. "Nine times a day, you will die if you live in a hurry, but you don't know where to go when you go out. Every time I think about my shame, I sweat! " . But the Historical Records is not finished yet, and I don't want to die. Sima Qian said: Zhou Wenwang was imprisoned to write Zhouyi, Confucius wrote Spring and Autumn Annals after suffering, Qu Yuan was demoted to write Lisao, Zuo Qiuming was blind to write Mandarin, Sun Bin was punished to write Sun Bin's Art of War, and was demoted to Shu, and Lu Chunqiu was handed down from generation to generation, Han Fei. These are the manifestations of the unremitting efforts of the sages in the predicament. Therefore, Sima Qian put forward the progressive view of life and death that "death is more important than Mount Tai and lighter than a feather". He also said that he was afraid that the article would not be handed down to the world. If historical records are passed on to the people, it will hurt most cities. Although I was killed, do you still have regrets? Therefore, future generations are fortunate to be able to read the swan song of historians with prosperous literature.
