Five years ago, neighbor Wang Defa forcibly took over more than a meter of the village road while building his house, arrogantly declaring, "If you think the road is too narrow, tear down your own wall!" Five years later, as he builds a new house for his son, the concrete truck is blocked by his own wall. Unwilling to tear down his own wall, he brings an excavator and forcibly demolishes the courtyard wall of Chen Jianshan's home! Facing threats, bribery, and false accusations, Chen Jianshan refuses to back down. He uncovers an old account book left behind by his father, along with crucial evidence, revealing a secret hidden for five years. In the end, Wang Defa not only has to pay compensation and suffer public humiliation but must also personally tear down the very wall he built to occupy the village road!
