'Zhèng tú' literally combines 'zhèng' (correct, proper, upright) and 'tú' (path, route, way), forming a compound noun meaning 'the right or proper path'—figuratively referring to a morally sound, socially accepted, or logically appropriate course of action or life direction. It carries connotations of legitimacy, virtue, and alignment with conventional wisdom or ethical standards.

The term is commonly used in formal or reflective contexts—such as education, career guidance, moral philosophy, or parental advice—to emphasize choosing responsible, constructive, and socially endorsed options over shortcuts or dubious alternatives. While it can describe literal routes in classical or poetic usage, modern usage is almost exclusively metaphorical, often appearing in phrases like '走正途' (to take the right path) or '唯有…才是正途' (only… is the proper course). It implies long-term value and social approval rather than immediate convenience.
