Hieu

Hieu is a common Vietnamese name derived from Sino-Vietnamese roots. The core meaning, 'hiếu', refers to filial piety, a virtue of respect for one's parents, elders, and ancestors. This concept is deeply ingrained in Confucian ethics and is a cornerstone of Vietnamese culture. The name reflects the high value placed on family and respect within Vietnamese society.

While primarily associated with filial piety, the name can also encompass meanings related to understanding, intelligence, and brightness, depending on the specific characters used in its written form (though often not explicitly differentiated in common usage). Its unisex nature highlights that these virtues are considered important for both males and females in Vietnamese tradition.
