Thirty years ago, the Zhou family thought the roadside land was barren and begged the Gu family to exchange it for the good fields by the river; thirty years later, roads were built, the poor land appreciated in value, and the Zhou family actually turned hostile to grab the land, destroying vegetables and injuring people! Gu Chengyu returned home to protect his father, keep evidence and pursue accountability, forcing the other party to recognize land ownership in public. Zhou Jianjun still refused to give up, built houses illegally after renting the land and ignoring warnings, and even made a counter-accusation to report Gu Chengyu. As hidden identities were revealed and recording evidence made public, the lies completely collapsed! The illegal construction was demolished, debts were recovered, and the Zhou family finally sold their house to pay off debts. Wanting to throw weight around to grab someone else's land, but ending up paying with one's own house!
