A kuài jià is a small utensil or stand used to hold chopsticks when they are not in use during a meal. It keeps the eating ends of the chopsticks clean and off the table surface, preventing contamination and maintaining hygiene. The word combines kuài (chopsticks) and jià (stand, rack, or support), literally meaning 'chopstick stand' — a transparent compound where both characters contribute directly to the meaning.

This item is commonly found in Chinese households and restaurants, especially in formal or traditional dining settings. Chopstick rests come in many materials — ceramic, wood, bamboo, or metal — and often reflect cultural aesthetics, sometimes featuring auspicious symbols or minimalist designs. While not strictly necessary for eating, using a kuài jià signals attention to etiquette and table manners, particularly when sharing dishes or hosting guests.
