At his master's request, Chen Feng spends five years repairing water, electrical systems, and household appliances for his neighbors free of charge, never worrying about personal gain or loss. But when Old Zhou, a neighbor who takes advantage of free services, is refused, he spreads false rumors and joins forces with others to misunderstand and ostracize Chen Feng. The property management office even issues a notice restricting him, and the rumors begin to affect his work. Without Chen Feng, the community finds itself unable to properly handle various breakdowns, leaving everyone filled with regret. After the community investigates and uncovers the whole truth, the residents collectively apologize and clear Chen Feng's name. Chen Feng chooses to help his neighbors again, but establishes reasonable rules, teaching everyone that kindness must have boundaries and that good neighborly relations depend on gratitude and mutual respect.
