Genealogy and genealogy are the life history of a family. It not only records the origin and migration of the family, but also includes the whole historical and cultural process of the family's residence, reproduction, marriage, culture, clan rules and family agreements.
Genealogy is a historical picture book centered on recording the lineage and characters of paternal families. It evolved gradually by recording the lineage and deeds of ancient emperors and generals. In the pre-Qin period, genealogies such as Zhou Guan and Shi Ben were circulated in the society. After the Qin and Han Dynasties, other genealogical works appeared, such as Chronicle of the Emperor, China People's Surnames, Customs and Surnames, etc. In the Wei, Jin, Southern and Northern Dynasties, the family tree became the main basis of marriage and official career between clans, so it developed rapidly. After the Sui, Tang and Five Dynasties, the wind of compiling music became more popular among the people from the official, and even spread to various families. Every family has a family tree, and every family has a family tree, which has never stopped. Therefore, every revision of music has become a major event between the same surname and the same family.
