What plus what equals what is the last name.

China is one of the earliest countries to use surnames in the world.

In fact, there are many kinds of surnames in China, some of which are based on ancestral totems or fetishes, such as dragons, horses and bears.

Some take fiefs or country names as surnames, such as Wu, Zhao and Song.

Some people take occupation or official position as their surnames. For example,' Situ' and' Sima' are ancient official names, fortune tellers' surnames are' Wu' and' Bu', rickshaws' car' and so on.

Others take mountains and rivers as their surnames. For example, Shennong lived in and some of his descendants took Jiang as their surname.

In addition, some people take their place of residence as their surnames, such as Dongguo and Ximen. The mention of these two surnames reminds people of the story of Mr. Dong Guo and Ximen Qing in Water Margin.
