Liaoning citizens were told to find shelter after it looked like it started to rain worms. A viral clip showed the area apparently being showered with little worms, which were splattered all over the cars. Cause of the slimy creature calamity is yet to be uncovered, but it has been suggested that the animals were dropped after being swept up by heavy winds.

This type of occurrence happens after a storm when insects are caught up in a whirlpool. Another theory suggested that the worms were actually poplar flowers—a tulip tree whose blooms resemble the squirmy beasts.
