An elderly couple sold their shop, holding 2.6 million, intending to test their children's filial piety, and falsely claimed to the outside world that the money was cheated, leaving only 80,000. Hearing this, the son's attitude changed drastically, changing the home's door password, arranging for the two elders to sleep on a folding bed, and even wanting to manage their pension. Meanwhile, the daughter with an ordinary family background brought the old couple over overnight to care for them meticulously. The elderly couple suddenly suffered a myocardial infarction and was hospitalized; the daughter accompanied and cared for them wholeheartedly without ever coveting their retirement savings. After recovery, the elderly couple handed the savings over to their daughter, having seen through this experience who truly cares about them.
