Serving Parents with Filial PietyThis twelfth-century-C.E. illustration of a passage in the Classic of Filial Piety shows how commoners should serve their parents: by working hard at productive jobs such as farming and tending to their parents’ daily needs. The married son and daughter-in-law offer food or drink to the older couple as their own children look on, thus learning how they should treat their own parents after they become aged.
