Da Qiang, who has achieved success in his career, returns to the old textile factory compound and spends thirty thousand yuan of his own money to replace the old water pipes for the neighbors for free. Unexpectedly, Zhao Cuihua on the first floor not only shows no gratitude, but also climbs onto an excavator, demanding thirty thousand yuan in compensation on the grounds of destroying feng shui. Da Qiang would rather pay extra to take a detour than indulge greed. After the new pipes are connected, the whole compound rejoices, except for the Zhao family whose old pipes are blocked and sewage backs up. Zhao Cuihua, caring too much about her face, couldn't bear to throw away the king crab soaked in sewage, ultimately resulting in both mother and son being poisoned and hospitalized, with their savings exhausted. The thirty thousand yuan wasn't extorted, but nearly forty thousand yuan was lost instead, and the greedy old woman finally tasted the bitter fruit of bringing it upon herself!
