The frost of the twelfth lunar month in 1985 fell on the loess slopes, and also fell on the newborn's first cry. Fan Shutong walked out of the shadow of the mountains step by step with the desire of his father's generation. From food stamps to stocks, from rural land to mortgages, from the admonition to "raise children for old age" to the cry of "Dad, don't leave", his forty years are a miniature history of the changes of the times. This is not the struggle of one person, but the story of how an entire generation puts its roots, marriage and future in the fast-moving train of the times.
