Who Owes Whom

This story tells of Liu Jin, who met a girl named Chen Fenfen while working in Jinwei. They were both twenty years old at the time. He lived east of the Taihang Mountains, she lived west of the Taihang Mountains. Fate brought them together, and fate also separated them. Within two months of knowing each other, Chen Fenfen followed Liu Jin back to his hometown. They were together for two or three years until she returned to her hometown. Liu Jin went to her hometown to look for her, but he didn't get to see her in person. Now, more than twenty years have passed, and Liu Jin still hasn't found the answer he's been seeking in his heart. If not owed in this life, we won't meet in the next; if we meet again in the next life, there must be a debt.
