Surnames are symbols that represent everyone and their families. In today's society, it has no meaning. However, from the long historical process of its formation, development and evolution, it is an important part of Chinese national culture. How did surnames come into being and develop? This is a very interesting subject, involving sociology, history, linguistics, philology, geography, folklore, demography, toponymy and many other social sciences. To understand the benefits of surname culture, genealogy is not only a historical reader of surname, but also a cultural reader of surname. Every family name and family is an important lineage of the Chinese nation, with its own culture and history. Many people want to know their surnames, especially the origin of their families. The most direct way is to find their genealogy, so that they naturally have a sense of belonging, identity and pride. Anyway, genealogy, as a unique highlight of China traditional culture, is the most authoritative record in this respect. Even if the surname is changed directly because of asylum, war, politics and other reasons, modern people's education, occupation, marriage, major achievements and other information can be included in the family tree. Knowing the surname culture can better understand a person's family origin. The origin of surnames can be traced back to the matriarchal clan system in primitive human society. Surname is a special symbol to distinguish clans. Many surnames in ancient China were beside the female characters, indicating that our ancestors had experienced matriarchal clan society. All surnames intermarry with each other, and intermarriage is prohibited within the clan with the same surname. The child belongs to the mother and takes the mother as the surname. The appearance of surnames is a sign that primitive people gradually got rid of ignorance. With the development of social productive forces, the matrilineal clan system has changed to the paternal clan system, and the surname has changed from the father's surname to the woman's family. Later, the clan system was gradually replaced by the class social system, and the methods and means of governing the country by naming the land came into being. The appearance of stone is a step towards class society in human history. Surnames and surnames are two stages of human progress and the product of civilization. China's surname has been born for 5,000 years, and its long history is extremely rare in the world cultural history. Surnames have long been a cultural phenomenon, and this social phenomenon is a special cultural phenomenon. Surnames (including first names) are formed on the hotbed of national culture, which is a rich spiritual mineral deposit. Developing this spiritual mineral deposit is of great practical significance for us to build a harmonious society today. So it's good for us to know the surname culture.
