Chàngyáng is a formal, written verb meaning 'to promote widely' or 'to extol' — especially in public, official, or ideological contexts. It combines 倡 (chàng), meaning 'to initiate' or 'to advocate', and 扬 (yáng), meaning 'to raise up', 'to spread', or 'to praise'. Together, they convey the idea of actively lifting up and disseminating a value, principle, behavior, or ideal so that others recognize and adopt it.

This word is commonly used in political, educational, and social advocacy settings — for instance, when authorities encourage virtues like honesty or environmental awareness, or when media highlights exemplary conduct. It carries a positive, commendatory tone and implies intentional, often institutional, effort. Unlike casual verbs like 宣传 (xuānchuán, 'to publicize'), chàngyáng emphasizes moral elevation and widespread endorsement rather than mere information dissemination.
