Superstition on white nails

White nails are unhealthy. In ancient times, old people thought that such people were blessed and brought bad things, so there was a superstition of white nails.

Superstition is a person's spiritual belief. No matter who or what kind of person, they can't tolerate questioning or mocking their beliefs. Therefore, if you really want to convince each other and get rid of feudal superstition, you must first express your respect for each other's beliefs and then gain their trust.
