Filial piety and the five relationships are most often associated with Confucianism, a philosophical system founded by Confucius in ancient China. Filial piety emphasizes respect and duty towards one's parents and ancestors, while the five relationships outline the hierarchical social structure that governs interactions among individuals, including ruler-subject, father-son, husband-wife, elder brother-younger brother, and friend-friend. Together, these concepts underscore the importance of familial and social harmony in Confucian thought.
