I'm the Good-for-Nothing Real Heiress, but I Know a Little Metaphysics

The seventh daughter, doted on by the entire Gu family, turns out to have been switched at birth! The real heiress who finds her way home is a good-for-nothing, can’t manage a single subject, and finds studying too exhausting. None of the capital’s elite have ever seen such a hopeless girl. The onlookers wait for her to make a fool of herself. But she becomes the idol of entertainment stars, an unofficial expert for the criminal investigation department, and a cherished guest of the city’s richest, all thanks to her fortune-telling, face-reading, and feng shui skills. She even helps her six brothers, each facing a long road to winning back his wife, reunite with their beloveds and bring their children home, completely turning the Gu family’s fortunes around! The spectators are left with their jaws on the floor, looking at the girl in a whole new light. Meanwhile, Second Master Qiao, the richest man in town, publicly declares, “My little Mo Qian can be a bit sharp-tongued. Just grit your teeth and bear it.” Everyone: “...” Is she just a bit sharp-tongued? Her words are practically blessed by the gods!
