Ching has multiple meanings depending on context:

• As a musical term/instrument: A pair of small bronze finger cymbals used in Thai and Cambodian music and dance; they are struck together to keep time and regulate melody. The sound is often described as a bright, tinkling ching/ching sound, and the instrument is typically mounted or held to be played in ensembles. This usage is common in Southeast Asian classical and theater traditions.

• As a dynasty name: Ching (also spelled Ch’ing) refers to the Manchu-led Chinese dynasty that ruled from 1644 to 1912.

• As a verb or slang in various colloquial contexts: “ching” can appear as a verb form in English meaning to chink or clink, especially when describing metal sounds, though this is less standardized and highly context-dependent.

If you had a specific sense in mind (the instrument, the dynasty, or another usage), I can provide a more focused explanation or examples.
