Dong Zhongshu was a thinker, politician and educator in the Western Han Dynasty. The earliest account of Dong Zhongshu was three years after Emperor Jing of Han Dynasty, and his status as a master of Confucian classics began to be recognized by the royal family. He was 58 years old when he became a famous star in the Han Dynasty. On the road to success, hardships are inevitable, but there is no record of his road to fame in the history books. Sima Qian, even his disciples, said nothing about his master's experience in Historical Records. A few vague words in the biography of Dong Zhongshu in Han Bangu are the only description of him. This man is very strict with himself and has strong self-discipline. From the age of 62 to 65, he still devoted himself to the study of Confucian classics. For the ancient people, this age is already very high, and his temples are all double hundred. I don't even know if the horse I'm riding is male or female, so I can forget all about eating and sleeping. Such self-discipline made him achieve such amazing achievements in the Han Dynasty and became a generation of scholars. (A scholar: a learned Confucian)
