High school student Lin Yang always takes Lei Feng as his model, integrating helping others into his daily routine. At school, he actively helps classmates whose academics are falling behind with tutoring, and steps in to share the difficulties encountered by his companions. Entering the community, he often visits to keep company with elderly people living alone, accompanying the elders to chat about family matters and helping to manage chores. Walking in the streets and alleys, he consciously discourages uncivilized behavior and maintains public order, and also actively takes the lead in building a bridge of mutual help among neighbors. Simple and heartwarming trivial matters allow the spirit of selfless dedication to take root and sprout, and also fill the youth of the teenager with positive power.
