仁爱 is a core Confucian virtue meaning 'benevolence' or 'humanity' — the love and compassion you feel for all people, not just family or friends. In Chinese philosophy, 仁 (benevolence) is the highest moral principle, and 仁爱 refers to the practiced expression of that benevolence toward others. It is used in formal and written contexts, especially in discussions of ethics, social harmony, and community spirit.
