When Sima Qian wrote Historical Records, he always adhered to the principle of loyalty and never took things personally. In the Biography of Li Guang, he described Li Guang's fighting tigers, retreating from the enemy and getting out of danger, which was vivid and true. Between the lines, full of admiration. But at the same time, he also wrote about his narrow-mindedness and the shortcomings of the official newspaper's personal vendetta against subordinates. He was full of sympathy for Xiang Yu, but described his doomed fate in detail; He hated Liu Bang, but truthfully wrote Liu Bang's strengths, talents and conditions for his inevitable success.

Sima Qian's Historical Records was written with a pragmatic attitude. Ban Gu, a historian of the Eastern Han Dynasty, commented on this book: "It is not empty, it is unstable, and it is evil."

2. Lu Xun is responsible for annotation.

Lu Xun translated the novel "Dead Soul" by Nikolai Nikolai Gogol, a famous Russian writer in the19th century, and turned to this sentence: "This is almost like the sculpture of Vinouse who just came out of the bath, but Lu Xun has never seen this sculpture, so he can't figure out the modality and position of the bather. Mr. Lu Xun has always been serious and never careless. He stopped writing and consulted various reference books. I heard that there is an art encyclopedia in Japan with this sculpture. He tried to buy it, but he still found nothing. After unremitting efforts, I finally found the statue, carefully studied the shape of the statue and wrote down my notes.

Li Siguang did this experiment by herself.

Is there geostress in this shell, and whether people living on the earth are directly affected by geostress? There are different opinions on this issue, and there is no conclusion. Li Siguang, a famous geologist in China, believes that scientists should seek truth from facts, and only through experiments can they explain problems. Nearly eighty years old, he personally led his assistant to do field experiments in the suburbs of Beijing, regardless of his weak health. He overcame the discouragement of his assistants and went to the machine in person, holding the cold iron handle, holding his breath, holding the iron handle tightly and keeping a close eye on the change of the instrument value. The results prove the existence of in-situ stress and the test is successful.

The water gushed out and the child was saved.
