There are four main sources of Mongolian and Han surnames:

1, taking the tribal name as the surname.

2. Take the family name as the surname.

3. Take the name of the ancestor as the surname.

4. Take China people's surnames directly, such as Wang, Li, Liu and Zhang directly.

Extended information Mongolian Han surname appears in mixed Mongolian and Chinese areas, and there is no Han surname in pure Mongolia, only Mongolian surname. Generally speaking, a tribe is a surname only if the people in this department go to other tribes, or if the tribe is integrated into other tribes. Since the Yuan Dynasty, many Mongolians have adopted China's surname and China's name, mainly for the needs of national communication.

In the Ming Dynasty, many Mongolians changed their surnames to the Han nationality, especially Mongolians scattered all over the country or in neighboring areas where the Han nationality lived. Today, surnames still play an important role in people's communication. When you touch someone, you can call them by their first name or their last name. There are generally three ways to produce Mongolian Chinese surnames: homophonic, transliteration and optional.

Homophony is to choose a syllable of Mongolian surname, translate Mongolian surname into Chinese, and take its word as Chinese surname; There is also the choice of characters, such as Weng Niute's family. He thinks that Weng Niute's family belongs to Gao's family, so his China surname is Gao's. Because of the inconvenient transportation and communication at that time, the same ethnic group in different regions had no time to discuss it, so the same Mongolian surname may have different Chinese surnames in different regions.
