Lin An was born into a poor farming and studying family. He was calm and filial, and never slacked off in studying hard. He was down-to-earth and worked steadily from scholar to scholar and tribute scholar. The book is free of nonsense and pretentiousness. It takes a warm family as the main line and describes the tender protection of parents, grandparents and sisters. In the end, he was a first-class scholar in the second class of high school in the imperial examination, counterattacked from a poor family, and glorified his ancestors, full of fireworks and a sense of healing.
