The story of the frog in the well sticks with Cunxin—and his brothers—throughout their lives; it will recur at key moments throughout the later chapters of the book. In essence, it describes a world like the one Cunxin lives in, a world where some people are limited by luck and circumstance to live difficult lives, while opportunity grants others access to a broader, brighter world. The frog father encourages his son—and by extension, Cunxin—to find happiness within the limits of his circumstances because escape is next to impossible. No matter how much effort the little frog puts into jumping and hopping, without some sort of extra help—some opportunity to propel him toward the surface—he will never escape the well.
