The word 穿过 is formed by combining two characters that each depict a physical action in sequence: 穿, which means to pierce through or penetrate (like threading a needle or entering a dense area), and 过, which means to pass or cross. Together, they create a single conceptual image of an action where one first enters into and then completes a movement through an obstacle or space, visually and notionally stringing the two stages into one complete idea of traversal.
