The origin of the surname Kong (1) is the descendant of King Shang Tang, with the original surname and the ancestral word as the surname. According to the classic Guang Yun, Qi is the ancestor of Shang clan and the surname of his son. After fourteen generations, it spread to Tang Cheng and destroyed Xia Jie. His name is Lu Zi, and he is a wise monarch. To commemorate the great achievements of his ancestors, one of his descendants merged his surname Zi and his first name B into a new word "Kong" and became a royal surname called Kong. ② In the Spring and Autumn Period, after Confucius was the father of Song Dynasty, he took the ancestral word as his surname. According to the records in Yuan He Xing Bian in the Tang Dynasty, in the early years of the Western Zhou Dynasty, Wei, the younger brother of Yin, died and his younger brother Yan succeeded to the throne. His great-great-grandson is testing his father, who is the supernatant of Song State. His son is called Jia. The descendants of Kong take their ancestors' names as their surnames, which are called Kong's. Confucius, a great thinker and educator in China, is the successor of this branch. (3) According to the historical book "Discrimination of Surnames in Ancient and Modern Times" and other related materials, there was a doctor named Gui in the Spring and Autumn Period in Chen State (now Huaiyang, Henan Province). Among the descendants of Guangxi, some people take the names of their ancestors as their surnames for refuge and call them Kong. (4) During the Spring and Autumn Period, Ji Kongmao was one of the doctors who defended the country. Luz, a famous disciple of Confucius, died to protect Ji Kongmao in a coup in the imperial court. Among Ji Kongmao's descendants, he took refuge, and some took their ancestral surname as their surname, called Kong. ⑤ According to historical records such as Kao's surname, Tongzhi Zongdao and Zuo Zhuan, during the Spring and Autumn Period, Zheng Guojun, Zheng Mugong Jilan (boasting about Xinzheng in Henan), was later named Ji, and some of his descendants took the name of their ancestors as Zheng Guokong. ⑥ Change the surname to Chinese surname. According to the historical records "Seven Strategies of Tongzhi in Qing Dynasty-Manchu Eight Banners Surnames", there are Kongguoluo, Kongnila, Kujala, Wentun and so on. And the last multi-crowned Han surname is Kong Shi. In addition, among the Mongolian, Tujia, Miao, Hui and other ethnic minorities, there are Confucius clan people. One of the birthplaces of Kong surname should be in Shangqiu, Henan Province today. The descendants of Confucius fled to Shandong to avoid disasters and settled in Shandong, which can be regarded as the first time that Confucius spread eastward. Moving eastward is of great significance, and later Lu became the residence of Confucius. After entering the Qin Dynasty, the Kong family has become a prominent family in Shandong, and has been migrating to neighboring provinces. In the Han Dynasty, some relatives of Confucius lived in Lu, offered incense to Confucius, and some became high officials of the dynasty, occupying a prominent position for a while. During the period of the Three Kingdoms, the Jin Dynasty and the Southern and Northern Dynasties, the northern part of the country was at war for years, and the people surnamed Kong moved southward again on a large scale and entered Zhejiang, Anhui and other places.
