号召

📣 号 = call/shout + 召 = summon; together: a public call to rally
号 means shout or signal; 召 means summon or convene. Combined, 号召 is a leader's public call summoning supporters to act — think of a rallying cry that gathers a crowd.
号 — mouth 口 + tiger 虎
Originally written 號, combining 口 (mouth, indicating a cry or call) with 虎 (tiger) as the phonetic and a hint at a loud roar. It first meant to shout or call out, then extended to a name, title, or signal. The simplified form 号 keeps only the upper element.
