Yan school is the origin or historical origin of surnames, but two aspects of surnames. Fang Chuan is called "Ding Hao", which means that the surname is one of them. Fang Chuan refers to the virtue and grace of an outstanding person in his surname, or his code of conduct and prestige that can set an example for future generations. For example, Chen's Fang and Lu's Wei Fang are more regional than Yan School, and even the same Yan School is different because of different regions.

Its historical allusion comes from the well-known story of Yang Zhen, an upright official in Han Dynasty: Yang Zhen went to Donglai to make a secretariat and passed Changyi. Wang Mi, the magistrate of Changyi introduced by Yang Zhen, arrived at Yang Zhen's residence with gold in the evening and wanted to give it to Yang Zhen. Yang Zhen refused and said, "An old friend knows a gentleman, but you don't know an old friend. Why? " Wang Mi said, "Ignorance is at dusk." Shocking: "Heaven knows, earth knows, son knows, I know, what is an ignorant person?" Wang Mi walked back guiltily.

For example, the descendants of Liehou in the Northern Song Dynasty, such as the descendants of Ming Taizu School, can write "Song Taizu Zhao Kuangyin School" or "Tianshui School", which is the concrete application of these two situations. What must be paid attention to here is the application of place name encyclopedia. The Encyclopedia of Place Names must have been the place name of the local aristocratic family, which makes future generations proud and can be used to express "merit".
