Paper Money for Shared Bikes

Around the Qingming Festival, folded paper money frequently appears in the baskets of urban shared bicycles. Operation and maintenance worker Xiao Sun thought it was a prank until folklorist Professor Gu discovered that each piece of paper money was folded in a different way, which happened to correspond to the names of old places in the city that had disappeared. Scanning records showed that the cars had been ridden near the cemetery. Following the investigation, they uncovered the secret operation of a 70-year-old man for three years - using shared bicycles to "visit the grave" of a disappeared old city.
