The Chinese word **口技 (kǒujì)**, meaning "vocal mimicry" or the art of imitating sounds, is a compound noun formed through semantic combination: the first character **口 (kǒu)** means "mouth," and the second character **技 (jì)** means "skill" or "art." Together, they create a straightforward and literal description—"mouth skill"—which precisely denotes the traditional performance art where an artist uses only their voice, mouth, and sometimes a microphone to produce vivid imitations of sounds from the human world, animals, and machinery.
