运转 (yùn zhuǎn) literally combines 运 (yùn, 'to move, to transport') and 转 (zhuǎn, 'to rotate, to turn'). Together, they describe the smooth, continuous operation of a system—especially mechanical, biological, or organizational processes. It emphasizes functionality, regularity, and dynamic activity, rather than static existence or one-time action.

This word is commonly used for machines (e.g., engines, computers), bodily systems (e.g., digestion, circulation), and abstract processes like economies or organizations. It implies proper, intended functioning—so saying something ‘is not运转’ suggests malfunction or breakdown. While often neutral in tone, it can carry positive connotations when describing efficient or healthy operation, especially in medical or technical contexts.
