Hey, I just learned. The back view is of Zhu Ziqing’s father selling fruit for him when his family was in trouble when he was a boy, which made him emotional and sad. It is to express his love for his father and his deep love for himself. The back is the bright line of the article, which shows the father's infinite love for his son. The way the father expresses his father's love is that the distant back is on the father's back. The greatness of father's love is read through the description of the father's farewell to his son at the station, which shows the father's meticulous love for his son and the son's longing for his father. It writes a sincere, deep and touching love between father and son. .
