Can a grandson take his grandfather’s last name?

Yes. This practice is relatively common in Chinese tradition and has also been recognized in modern law.

1. According to the "People's Republic of China and the Civil Code", citizens have the right to choose the surnames of other direct elders and blood relatives. This includes grandchildren following the surnames of their ancestors. This practice does not violate legal provisions.

2. The surname refers to the ancestral origin of the family; the surname refers to the place where the descendants are divided; "the surname is the symbol that marks the bloodline of the family." According to research, ancient Chinese surnames originated from totem worship and were clan emblems or symbols.

3. The origin of surnames can be traced back to the matriarchal clan system in primitive human society. Therefore, many ancient Chinese surnames have the character female beside or at the bottom. There are no regulations on the distinction of surnames in pre-Qin literature. The distinction of surnames is a theory created by later generations.
