An old man disguises himself as poor to return home and test his children's true feelings. During the family property division, all the children view him as a burden, shifting responsibility and unwilling to support him, except for his honest youngest son who takes him home to care for him attentively. No one knows the old man holds a fortune. As the news spreads, the other children come flocking to please him and vie for benefits. Seeing through their hypocrisy, the old man funds his youngest son's business startup. After the youngest son achieves success, he sets up a fund with the returns to help lonely and foolish elderly people, showing that genuine affection through adversity is the most precious thing of all.
