Retired father Chen Hongyuan lives alone in a river-view apartment. His son Chen Kai and daughter-in-law Wang Zhiyi use the excuse of her father's bad knee to force him to return to the old rural house, clearing out the apartment for her parents to live in. They bought a sleeper train ticket in advance, assigned rooms, canceled his living arrangements, and even brought people to measure the apartment and forcibly move, just wanting to trade the father's 2.8 million property for a sleeper ticket worth just over three hundred. Chen Hongyuan feigned agreement to arrange it himself, secretly listed the apartment for sale, and publicly sold the apartment in full to Li Yanshen at the transaction center, completely shattering his son and daughter-in-law's scheme. After their attempts to cause trouble and demand retirement money both failed, Chen Hongyuan bought a small apartment to live alone, kept his retirement money, and lived for himself.
