N) Surnames come from three sources:

1, from Ji, later, taking the country name as the surname. According to a brief history of clans, the origin of China's surname, Guang Yun, Zhou Wuwang established the Zhou Dynasty after the demise of the Shang Dynasty, made his third brother Xian Shu, who was called in charge in history (now Zhengzhou City, Henan Province), and established a state, allowing him and Cai Shu to manage the adherents of the Shang Dynasty together. After the death of King Wu, the young king succeeded to the throne. Being too young, Zhou Gongdan presided over state affairs. Guan Shu and Cai Shu thought that Zhou Gongdan's rule was not conducive to the Zhou Dynasty, so they joined forces with Wu Geng to launch a rebellion, which was quickly quelled by Zhou Gongdan. After he was killed, his descendants took his former fief "Guan" as their surname and called it Guan.

2. The surname Ji, followed by the surname Yi. According to the records in Genealogy and Custom Brief, when Zhou Muwang was in power, his illegitimate child was enfeoffed in Qi until Guanzhong, and then his grandson took Yi as his surname. Guan Zhong was a famous politician after Zhou Muwang in the Spring and Autumn Period. Later, he became the prime minister of Qi, helping Qi Huangong to govern the country. The descendants of Guan Zhong are also named Guan, known as Guan.

3. Change his surname from his home. Xibe nationality is Guarga, and Han nationality is Guan. Ancestor: Guan Zhong. Real name Yi Wu, Zun Zun, also known as Zhong Jing. Yingshang (present-day Anhui) was a famous politician after Qi in the Spring and Autumn Period. Guan Zhongyuan assisted Miyako for a long time and shot Xiao Bai with an arrow. Xiao Bai escaped by playing dead, and Xiao Bai returned to China to reign, that is, Qi Huangong. He let bygones be bygones and reused Guan Zhong as a relative. Guan Zhong was very grateful and helped Qi Huangong to carry out reforms. He accumulated wealth through money, respected the king to conquer foreign countries and the world, making Qi Huangong the first of the five tyrants in the Spring and Autumn Period. Guan Shu was killed because of the rebellion, and his reputation was ruined, while Guan Zhong was famous, having both ability and political integrity, which made the surname Guan Shu, the ruler of Mu Wang, famous all over the world. Therefore, the descendants of Guan Xing respectfully call Guan Zhong the ancestor of Guan Xing.
