When I went to Jinzhai Jade Expo Scenic Area last time, I saw a cultural company called Family Tree International. Do you know what this company does?

To put it simply, those who compile family trees.

In detail (I just found Du Niang):

Family Tree International promotes family culture. Based on the Internet, it helps major surnames to sort out their family lines and revise and continue their genealogy. , establish family archives, create root-seeking travel routes and other professional clan service organizations.

Note

Family tree: also known as genealogy, genealogy, etc. It is a book that records a family's lineage and the deeds of important figures in the form of a genealogy. The emperor's genealogy is called a jade certificate, such as the New Dynasty Jade Certificate and the Imperial Song Dynasty Jade Certificate. It focuses on recording the paternal family lineage and characters, and evolved from the chronicles of emperors, biographies of princes, and chronology in official history.

A family tree is a special kind of document. In terms of its content, it is a document with civilian characteristics in the five thousand years of Chinese civilization. It records the people and deeds of the blood group of the same ancestors. Historical records of the situation. Genealogy is a precious humanistic material, which has its unique and irreplaceable function for in-depth research on history, folklore, demography, sociology and economics.
