On the very first day Li Xiang moves into Sunshine Garden, an exorbitant faucet repair bill stops him at his own front door: replacing a faucet costs 5,000 yuan. Xiao Cai, the property management attendant, wears a professional smile and shuts down every objection with a single phrase: “Those are the rules.” Li Xiang remains calm and immediately exposes the truth: the valve core costs only 30 yuan. He casually takes out his phone to photograph the bill and mentions that he once won a similar lawsuit against a property management company. Other homeowners in the lobby quietly prick up their ears. But as soon as he returns home, the faucet lets out a single choking groan—and the water supply is cut off.
