The Chinese word 管道 (guǎndào) for "pipeline" is composed of two characters: 管 (guǎn) and 道 (dào). The character 管 originally meant "bamboo tube" or "pipe" and was later extended to mean "to manage" or "to control". The character 道 originally meant "path" or "road" and was later extended to mean "principle" or "way". When combined, the two characters 管道 literally mean "pipe road" and figuratively refer to a pipeline or conduit for transporting fluids or gases.
