Life Is a Long Quiet River (1988)

Because obstetrics and gynaecology nurses confessed to swapping rich middle-class Quesnoy boys with lower-class Groselle girls 12 years ago, Quesnoy now doesn't want to return her daughter and wants to buy her son Momo. Momo is a precocious, smart, smooth and habitual thief who grew up in a rough and harsh family environment, but when he arrived at Quesno's house, he made them restless. This is a social satire, shelling the rich and the poor at the same time. The story is about a nurse who had an affair with her boss and deliberately switched two newborn babies. Twelve years later, the boss's wife died, but he didn't want to marry his mistress, so she broke the secret, plunging two families with a clear gap between the rich and the poor into their own crisis. The rich family is willing to take their children back, while the poor family is desperately blackmailing; when the poor daughter returns to the rich family, she brings many of her old habits with her; the rich daughter is curious about her own parents, but they don't want to take her back.
