Yellow croaker migrates back in spring, and overwinters in the southeast sea in late autumn and early winter. Our ancestors did not know the migratory characteristics of yellow croaker, and they suddenly disappeared in late autumn and early winter; At this time, as migratory birds, a large number of wild ducks arrived, and they just had stones on their heads, so they thought it was melted by yellow croaker.
