Travelers and goods from all directions converged here like spokes to a hub.
Tips
history
Not used alone in modern Chinese. It survives in the literary compound 辐辏 (spokes converging on a hub, hence 'to converge from all sides'); everyday Chinese uses 聚集 instead.
memory
The cart radical 车 points to a wheel; picture every spoke 辐 running inward to one center, that gathering-to-a-point image is 辏.
