Liu Chen and Ruan Zhao, two men of the Eastern Han, went into the Tiantai Mountains to gather medicinal herbs and lost their way. After days of hunger they came upon two immortal women, who welcomed them, fed them sesame rice, and married them. Half a year later the men grew homesick and went down the mountain, only to find that seven generations had passed and no one knew them. When they tried to go back, the path had vanished. The tale comes from a fifth-century collection of marvels, and temple books set it beside the image of boring for a spring with an awl. The fit is in how the men found wonders: only after they were lost, by chance rather than effort. That is why this middle stick rewards the unplanned meeting more than the hard dig.
