Lin Xi's family encountered robbers on their way south to visit relatives, and he was the only one in the family of four who survived. When he was dying, he was picked up and taken home by Wei Shan.
Wei Shan was a poor child. He lost his mother when he was born, his father when he was eight years old, and when he was fourteen, the old scalper who had been accompanying him also left him. He thought he would be alone from now on, but when he was fifteen, he picked up Lin Xi who was unconscious on the roadside.
The two have been together day and night for four years.
Four years later, Lin Xi's uncle came looking for him and wanted to take Lin Xi away.
