We took young person Lin Sen as leading character to narrate the growth stories of youth, revealing secretly value collision of two generations by taking ways of education as the theme. The junior school students under the writer's work had distinctive personality, they were at the best age of learning, but always unkind to institutionalized school life; they wanted to be leading characters, but they did not know the meaning of real leading character; they had joy and sorrow, friendship and quarrel, revolt and compromise. They finally understood they always accompanied with each other to compose the poem of youth belonging to them all. The work has ups and downs story plots and continuous conflicts, which is an excellent youth literature.
