Under Yanhongling

In Yanhongling somewhere in the south of the motherland, there are many revolutionary stories of Red Army heroes. At the foot of Yanhongling, there is a school for the children of railway workers. Yang Qinghu, a fifth-grade primary school student, and his friends often go to Yanhongling for "military exercises." In Qing Hu's picture book, the paintings are all heroic figures such as Huang Jiguang, Dong Cunrui, Lei Feng, etc., but he lacks proper understanding of the relationship between ordinary labor and revolutionary heroes. During a storm, flash floods broke out, damaging the railway and stopping the trains. The flood-fighting commandos braved the heavy rain, gathered urgently, and rushed to the flood-fighting front line.
