Sima Qian has such a passage in "Preface to Shi Ji Tai Shi Gong": "Move Longmen, plow the grandson of rivers and mountains." Ten years old, you recite ancient Chinese. In the 20th century, I traveled south to the Yangtze River and Huaihe River, visited Huiji, explored Shu points, and became suspicious, floating in Yuan and Xiang. The north is involved in writing and thinking, talking about the capital of Qi and Lu, observing the legacy of Confucius and shooting Zou and Yi in the countryside; Trapped in the province, Xue, Du Liang, Chu Gui. So he moved to be a doctor, sent to the west to levy on Pakistan, slightly in southern Sichuan, and went to Qiong, Henan and Kunming in the south, and also reported his life. "
Sima Qian was born in Longmen and lived a farming and pastoral life in Shan Zhinan, Longmen, north of the Yellow River. At the age of ten, he had learned ancient Chinese. At the age of 20, he began to travel to Jiangnan and Huaihe River, climb Huiji Mountain, explore Jade Cave, visit Jiuyi Mountain and go boating in Hunan Water God. Go north to Wenshui and Surabaya, discuss knowledge in Qi and Lu cities, inspect Confucius' legacy, and shoot in Zouxian and Yishan countryside; Embarrassed in Pu, Xue and Pengcheng, he passed through the land of Liang and Chu and returned to his hometown. So Sima Qian became an official and became a doctor, and was ordered to send envoys to the west to the south of Bashu, to Qionglai, Sichuan and Kunming, and to report back to the court.
