About
坰 is a phono-semantic compound: the left radical 土 (earth, soil) places it in the semantic field of land or terrain, while the right component 向 provides the pronunciation "shǎng". As a noun, it denotes a traditional unit of land area historically used in northern China. The exact area varied by locality and period, making it a regional agricultural measure tied to local farming and land administration rather than a standardized unit.
