Out of neighborhood affection, Song Dehou sold his plough ox and took out twenty thousand in hard-earned money to sponsor Qian Zhiyuan in attending university. After Qian Zhiyuan passed the civil service exam, he instead reported the Song family's melon field, causing the Song family to be fined to shovel away the melons. The Qian family father and son denied the loan, making things difficult for the Song family in many ways, and Song Dehou fell seriously ill and became disabled. The original loan note was stolen, and the Song family protected their rights by relying on account books, photocopies, and recording evidence. Facing Qian Zhiyuan's threat against Song Nian's future, neighbors stepped forward to testify. The court ruled that the Qian family must repay the money, Qian Zhiyuan's public service employment was revoked, and related illegal construction and shielding cadres were investigated and punished together. The Song family reclaimed their melon field, and life returned to the right track.
