🛒 顺 follow + 便 convenient = while you're already going, do it too
顺 — 川 (river) + 页 (head/face)
顺 combines 川 (flowing river) with 页 (head), originally depicting a head turned to follow the flow of water. The image of going along with the current gave rise to meanings like 'to follow,' 'smooth,' and 'in order.' It remains tied to ideas of compliance and natural sequence.
便 — person 亻 + change 更
A semantic compound: 亻(person) beside 更 (to change/replace). The original sense was a person making things easier or more convenient by adjusting them. From 'convenient' it extended to 'then/thereupon' (biàn) and to bodily 'discharge' (as in 大便).
