Disabled textile factory female worker Lu Guifen uses her work-injury compensation and lifelong savings to buy a river-view large flat in full, as a bridal chamber for her only son. Who knows, the ungrateful son is instigated by his snobbish daughter-in-law's family, occupies the property, and even drives her to the garbage station to pick up scraps, throwing even her late husband's portrait into a garbage bag as unlucky. Lu Guifen is clear-headed with zero internal friction, selling at a discount and cashing out in full within three days. While the Wang family is throwing a housewarming banquet and showing off boastfully in front of all relatives, she storms in to clear the venue with the new owner and property management, sweeping this family out the door in public. From then on, she no longer pins her hopes on "relying on children to provide for old age".
