example
In the fourth year of Jian 'an (199), Yuan Shao sent 100,000 troops and 10,000 cavalry in an attempt to seize Xudu, recapture Emperor Wu of the Han Dynasty, and destroy Cao Cao, so as to take the position of Han Dynasty. As a result, he didn't expect to openly oppose the imperial court because he was a nameless teacher, which made him very angry and was finally defeated by Cao Cao. However, Cao Cao succeeded in "relying on heaven to make princes" and soon promulgated the famous "order for seeking talents" in the name of the son of heaven.
Except Cao Cao, no one can understand the influence of this kind of "seeking talents to make orders" on scholars all over the world. At the beginning of Jian 'an, the north gradually stabilized, and Cao Cao has been recruiting talents. Coupled with the new construction of Xudu, when the "order for seeking talents" came out, Jiangdong guests and friends responded strongly and scholars from all over the country gathered. Xu Yi, Wang Lang, Xu Xuan and Chen Jiao, the famous figures recorded in the Three Kingdoms, all withdrew from Sun Ce's life, and the north belonged to Cao Cao.
Cao Cao recruited talented people in the name of seeking talents in the imperial court, but all talented people knew that Cao Cao was really in power, so they went to him more actively. In this way, Cao Cao not only gained the reputation of being a loyal minister and a good general in name, but also gained many capable people. Therefore, Cao Cao has a great advantage in this talent competition, because he is a famous teacher. Therefore, it is natural for Cao Cao to develop his strength with the help of the son of heaven, but he still acts in the name of the son of heaven.
The Book of Rites under Tan Gong
The Book of Rites of Tan Gong Xia was written by Confucianism from pre-Qin to Han Dynasty, and compiled by Dai Sheng in Western Han Dynasty, which originated from The Book of Rites. The Book of Rites is an important book of laws and regulations in ancient China. This book was compiled by Dade, a Li Shi in the Western Han Dynasty, and his nephew Dai Sheng. Eighty-five pieces of Selected Works of Great Virtue were called "Dai Dai Li Ji", but in the later circulation process, only thirty-nine pieces were left in the Tang Dynasty.
Dai Shengxuan's forty-nine articles are the Book of Rites of Little Dai that we saw today. These two books have their own emphases and choices, and each has its own characteristics. At the end of the Eastern Han Dynasty, Zheng Xuan, a famous scholar, made an excellent interpretation of The Book of Rites of Little Dai. Later, this book became popular, and gradually became a classic from the works explaining the scriptures.
It is listed as one of the "Nine Classics" in the Tang Dynasty and one of the "Thirteen Classics" in the Song Dynasty, and it is a must-read book for scholars. There are 49 articles in The Book of Rites handed down from generation to generation with Zheng Xuan as the annotation.
