Why are fairy tales broken?

"People's knowledge comes from practice, serves practice, develops with practice and is tested by practice." However, "cognition is the dynamic reflection of the subject to the object." Since it is active, there is imitation and creation. "In the cognitive process, there are not only the acceptance of human object information, but also the analysis, selection, application, reorganization, integration, construction and virtuality of object information." Fairy tales come from the virtuality of cognition.
