Lin Mo gave 500 yuan a month to support a primary school student named Liu Tiejun in a mountainous area whose parents had both died. This support lasted for 8 years. However, Lin Mo did not expect that Liu Tiejun was a girl. After the death of his only relative, his grandmother, when he was 16 years old, he wrote to Lin Mo saying that he no longer wanted to study and would repay his kindness by working in the future. Lin Mo decided to go into the mountains to find someone.
