About
The character 洫 (xù) is an agricultural and environmental term formed with the water radical 氵 (shuǐ) on the left and the phonetic component 血 (xuè, meaning blood) on the right. While 血 provides the pronunciation, the water radical determines its meaning, which refers to a man-made ditch, drainage channel, or small moat used for irrigation. Historically, this character was vital for describing the water management systems essential to ancient farming and field division. It frequently appeared in texts concerning land management, agricultural engineering, and local infrastructure. The definition remains strictly tied to these practical water channels, anchoring the character in its original, concrete context rather than extending into abstract metaphorical uses.
