What is the significance of studying folklore?

Life is folklore, folklore not only refers to a material existence, but also refers to a psychological accumulation. For example, if you watch a TV drama and see the same character and the same thing performed, different scriptwriters and different actors in Hong Kong, Macau, Taiwan and mainland China will perform different characters and use even the most similar or identical props, but as an individual, you still feel that there are differences. Herein lies your psychology, the psychology of the other party, which, in fact, are all products nourished by folklore. We grew up, never someone will tell you, pay attention, this is folklore, you should be so, but you are always observing ah, simulation ah. For example, eating posture, preferences for food, has gradually developed into a memory of things, and finally became a collective folklore in the individual composition.
