Which virtue in Confucianism represents the deep respect for family and elders?

The virtue in Confucianism that represents deep respect for family and elders is best captured by the concept of filial piety. Filial piety, or "xiao," emphasizes the importance of honoring one’s parents and ancestors, reflecting a fundamental value in Confucian thought. This virtue underscores the duty of children to care for and respect their parents, maintaining family harmony and integrity.

In Confucianism, filial piety is not just about respect; it encompasses the responsibilities and obligations owed to parents and elders, celebrating the familial bond and cultural continuity. The emphasis on familial relationships and respect for tradition is central to Confucian ethics, playing a crucial role in social harmony and the moral development of individuals.

While "ren" refers to benevolence or humaneness and "li" denotes proper behavior or ritual, the distinct focus of filial piety specifically aligns with the overarching theme of respect for family and elders. This makes it the most fitting choice in the context of deep familial respect.
