At sixty-eight, Zhou Guilan receives demolition compensation and evenly splits six million to fund her grandson and maternal grandson for overseas studies. Three years later, grandson Zhao Zihao returns to prepare a celebration banquet and promote a financial investment project; maternal grandson Jiang Nian'an returns exhausted.

He exposes diploma doubts and financial traps, dissuades the villagers, and fully demonstrates a devoted original intention, contrasting different choices in life.
