Benzhuang, a famous scholar and poet in the Western Han Dynasty, was later called "Master Yan". His works are very rich, with 24 words and poems, but only one "Mourning for Time" has been handed down to this day, which is a work in memory of Qu Yuan. History in the Eastern Han Dynasty, because of Liu Zhuang, ordered Zhuang to change his surname (the name of the ancient emperor could not be used by his subjects). Yanji's surname is strict, and it is also after death. Yan clan people regard him as the ancestor of Yan family because of their dignity and reputation. Yan's genealogy records: "Yan was born in Zhuan Xu, and posthumous title was his surname", "Ji's ancestral tomb, originally named Zhuang, covers descendants". Later, due to avoiding the name of Liu Zhuang, the Emperor of the Han Dynasty, Zhuang was changed to Yan, so Yan was taken as his surname. The book "Seeking the Roots of China's Surnames" also said that "Yan was changed by Zhuang's family" and "Yan restored Zhuang's family in Wei and Jin Dynasties, thus forming two solemn families." The two families are originally a family, so there is an old saying that "serious people don't get married." Yan has six sources:

1, from Zhuang's surname, changed his surname to Yan to avoid the name of Liu Zhuang. According to "Tongzhi Genealogy Taking History as Family Name", in the Eastern Han Dynasty, in order to avoid talking with Liu Zhuang, Zhuang changed his surname to Yan. In the Wei and Jin Dynasties, some people with strict surnames resumed their original Zhuang surnames. In this way, Zhuang surname and Yan surname coexist in the world. Therefore, there is a saying that "the Zhuang and Yan families can't marry with the same surname".

2, from the surname mi, after the Warring States period, posthumous title as the surname. According to Yuan He Shi Bian, "Mi Shi is his grandson and Shi Shi is his surname." Mi surname can be traced back to Zhuan Xu, a descendant of the Yellow Emperor.

3. After Yan died of illness in the Warring States Period, he was given the title of surname. Qin Youyan, whose surname is Yan in Fengyandao County (now Yingjing, Sichuan Province), was passed down from generation to generation.

There have been strict countries since ancient times, and China people take the country name as their surname. According to the surname test, there was a strict country in ancient times, and China people took the country as their surname.

5. Dingling people have strict surnames. According to the Book of Jin, when Hou Yan was Murong Sheng, there were people in Dingling who took Yan as their surname.

6. People from ethnic minorities have strict surnames. Manchu, Yi, Tu, Xibe, Korean and other ethnic groups all have Yan surnames.

Ancestor: Yan Ji. Yan Ji, whose real name is Zhuang, was a famous scholar and poet in the Western Han Dynasty, and was later called "Master Yan". His works are very rich, with 24 words and poems, but only one "Mourning for Time" has been handed down to this day, which is a work in memory of Qu Yuan. History in the Eastern Han Dynasty, because of Liu Zhuang, ordered Zhuang to change his surname (the name of the ancient emperor could not be used by his subjects). Yanji's surname is strict, and it is also after death. Yan clan people regard him as the ancestor of Yan family because of their dignity and reputation.
