Pouring one's heart out to help everyone solve difficult problems, yet ending up receiving a report. A surge of goodwill is questioned, leaving mixed feelings inside. The lens records the true daily life of a grassroots repair master, with no script, filled entirely with emotional and human difficulties in reality. Can it be that helping selflessly and for free would also be misinterpreted by others?
