At the turn of the century, the mountain road in Shibali Village was treacherous, and villagers relied entirely on Lin Yuan's tractor to get around. For ten years, Lin Yuan helped his neighbors without asking for anything in return. But when a family crisis left him desperately needing money, the villagers misunderstood him even though he charged only enough to cover basic fuel costs. After enduring numerous hardships, everyone finally realizes that selfless generosity should never be taken for granted. The entire village abandons emotional blackmail and jointly establishes transparent, publicly disclosed rules. By repairing the road, standardizing transportation, and relying on collective effort, they open up a vital lifeline for survival. Lin Yuan lays down the burden of personal sacrifice and sets off toward a new life. The story shows that rules must take precedence over personal relationships, and that only through collective construction and shared benefits can the livelihoods and peace of an entire community be protected.
