沖

• Hydraulic/Fluid Force: To pour, steep, or infuse; to rinse or wash away debris; the erosive force of water (e.g., flooding or washing away a bank).
• Kinetic/Linear Force: To rush, charge, or bolt forward; collision, clashing, or striking with momentum; breaking through a barrier or breaching a line.
• Hollowness and the Void: In philosophical or metaphysical contexts (notably Taoist), refers to emptiness, hollowness, or an open center—a state of receptivity or a vacant space for the flow of energy/breath (//qi//).

• Transitive: Typically takes an object (e.g., the substance being steeped or the barrier being breached).
• Intransitive/Directional: Can function as a verb of motion toward a specific destination.

The glyph is largely interchangeable with 衝; the distinction between the "water" radical and the non-water variant is often negligible, as both center on forceful movement or an open passage.

Semantic and simplified variant: 衝 (U+51B2).

Determine if the context is hydraulic or kinetic. In early texts, if the "water" sense seems incongruous with the level of violence described, treat it as 衝 (charge/collide). In metaphysical passages, prioritize "emptiness" or "void" over literal pouring or rushing.
