Fang Qinghe was kidnapped and lost his memory in his early childhood, wandering for twenty years. He jumped into the river to save Huo Zhenshan's grandson, and was rewarded with one million in cash and a six-million bank card. He returned to the old Fang family residence, where his third older sister, Fang Xiuyun, recognized him by a birthmark, while his oldest older brother and second older sister initially refused to acknowledge him. After recovering his memory, he continued to play the fool to see through human hearts. In the end, those involved in the case were arrested, and judicial appraisal confirmed his identity. He bought a house for his third older sister, fought back the old residence, started a family with Su Qingyue, and donated ten million to establish the "Fang Deshan Homegoing Plan" to help kidnapped children return home.
