What is the relationship between the main features of Korean etiquette culture and the ancient traditional culture of China?

After the demise of Shang Dynasty at the end of the Western Zhou Dynasty, Ji Zi, a follower of Shang Dynasty, went to the Korean Peninsula and established the "Ji Hou Guo" with the local indigenous people. At the end of 3rd century BC, it was recorded for the first time in Korean history. According to Records of the Historian written by Sima Qian, a historian of Han Dynasty in China, Ji Zi, the younger brother of the last king of Shang Dynasty, brought the etiquette and system of Shang Dynasty to the northern part of Korean Peninsula after Zhou Wuwang conquered it, and was elected as a monarch by the people there and recognized as a vassal by Zhou Dynasty. Historically known as "Jizi Korea".

Lu Wan, the prince of Yan in the early Han Dynasty, betrayed the Han Dynasty and fled to Xiongnu. His Ministry will lead more than a thousand people to enter Korea with Wei Man, the general of Yan State, and become the palace of Jizi North Korea. In BC 194, the regime of ji zi was overthrown in Pyongyang. This is the second dynasty in Korean history, called Wei Man Korea.

Korean culture is obviously influenced by China. As early as the Tang Dynasty, Silla on the Korean Peninsula sent people to China to study China's culture and strategy of governing the country, and even brought some things back directly. China culture had a long-term influence on Silla, which was strengthened by absorbing China culture, thus unifying the Korean Peninsula.
