Jizi is one of the "three benevolences" of the Yin Dynasty praised by Confucius. In the early years of the Western Zhou Dynasty, Jizi left the Central Plains and moved east to the Korean Peninsula. King Wu of Zhou made him a Marquis of Korea and implemented the "Eight Principles of Teaching" in the local area. The Ji family has been operating in the Korean Peninsula for more than 800 years and is a princely state of Zhou Dynasty. At the end of the 4th century BC, the Zongzhou rites collapsed, and the Marquis of Yan and others pretended to be kings, and the Marquis of Joseon subsequently called himself the King of Joseon. After the establishment of the Qin Dynasty, the Ji family belonged to Qin, and at the same time had contacts with surrounding forces such as Qi, Yan, and Donghu. In 195 BC, Wei Man of the Yan people replaced the Ji family and became the king of Korea, and Korea entered the era of "Wei family" rule. Jishi Korea played an important role in promoting the civilization, rituals, music, economic development and other historical processes of the Korean Peninsula.
