弘扬
hóng yáng · HSK 7
to promote
📣 弘 = vast/enlarge + 扬 = raise up, spread = to spread something widely = promote
扬 also appears in 表扬 (to praise) and 宣扬 (to publicize), all sharing the sense of raising up and spreading word. 弘扬 is usually applied to abstract things: culture, spirit, or tradition that you broadcast and enrich.
扬 — hand radical 扌 + 昜 (rising sun)
扬 is a semantic-phonetic compound: the hand radical 扌 gives the meaning (an action done with the hand), while 昜 (sun rising over the horizon) supplies the sound 'yáng'. The original sense was to raise or lift up, which broadened to 'spread, scatter, make known'. The modern simplified form replaces the older 揚.
