"Youth Jianghu and Boundary Monuments"
The first half of the story, "Young Jianghu", refers directly to the disputes between street clubs, the collision of fists and loyalty in the early stages of the story, and restores the passion and chaos on the vocational high school campus; the second half, "Boundary Monument", symbolizes the national border guarded by the father, the bottom line of life that the teenagers ultimately adhere to, and the clear dividing line from "jianghu" to "the right path." The strong contrast between the two not only reflects the conflicting tension of the story, but also highlights the core theme - the teenagers struggled in the quagmire of the rivers and lakes, and finally found a "boundary monument" worth protecting than the street forces, completing the transformation from impulsive to responsible.
