U+5621 "嘡" CJK Unified Ideograph-# Unicode Character

U+5621 "嘡" CJK Unified Ideograph-# is a Chinese character (Hanzi) that primarily functions as an onomatopoeic word, commonly used in Mandarin to represent a loud banging, clanging, or crashing sound, such as the noise of a door slamming or a heavy object falling. It is composed of the radical "口" (mouth, relating to sound or speech) on the left, and the phonetic component "堂" (táng, meaning hall or room) on the right, which provides a clue to its pronunciation (pronounced as tāng in Mandarin). This character is relatively rare in contemporary written Chinese and is more often encountered in colloquial or literary contexts, particularly in novels or dialogue when describing sudden, sharp auditory events.
