'Huī shǒu' literally means 'to wave (one’s) hand'—'huī' conveys the action of swinging or moving something back and forth, while 'shǒu' means 'hand'. Together, they form a common verb describing the deliberate, often friendly or farewell-oriented gesture of moving the hand through the air. It is used in both literal and figurative contexts, such as greeting someone from afar, saying goodbye at a train station, or signaling attention.

This verb is typically used intransitively (no object required), though it can take a directional complement like 'huī shǒu zǒu le' (waved and left) or be modified by aspect particles like 'le' or 'guo'. It appears frequently in spoken Mandarin and everyday writing, especially in descriptions of interpersonal interactions, travel scenes, or emotional farewells. Unlike some gestures, 'huī shǒu' carries a neutral-to-positive connotation and rarely implies urgency or command.
