The protagonist is Amway Ke, a student who has just entered the third grade. His father is an engineer and his family is in good condition. His parents often teach Amrico to be a good person and always help people in need.

Amrico has a group of kind-hearted classmates. After learning that Amrico's father came back from prison, the enthusiastic monitor kept a secret for his self-esteem. Amrico's most admired person is Caron, and his father is a train driver. Under his influence, Caron has a noble heart and often stands up when he sees weak students being bullied. Nobis, the son of a gentleman, and Betty, the son of a charcoal seller, often quarrel over trifles, but under the guidance of their parents, they became close deskmates.

Julia is exhausted to help her father write official documents, but she still has to face accusations and incomprehension from her family. Julia put up with it and continued to copy the official documents for her father. Later, her father learned the reason for his decline in grades, and the father and son embraced and cried.

The headmaster of Amrico is an old man. After the death of his son, the headmaster often takes his students to see the passing troops, educates them in patriotism and learns from them.

When I graduated, Amway was reluctant to part with my classmates and teachers, and my heart was filled with infinite gratitude.
