Chen Mo is a down-and-out restorer of ancient books. He runs a "Mo Zhai" on the verge of bankruptcy in the old city. His ancestral restoration skills are no longer interested due to the impact of modern technology, and he still owes loan sharks. He has a withdrawn personality, and is obsessed only with a incomplete copy of "The Secret Map of Kunyu" - this is an only copy that was half-restored during his father's lifetime. It is said to contain clues to the water transport treasures of the Ming Dynasty, and was also the cause of his father's "accidental death".
