Why are superstitions a product of culture?

Superstition is a product of culture and is closely related to the values, cosmology, philosophy and beliefs of a particular culture. In traditional Chinese culture, black is the color of evil, and people usually use black only after a death in the family. Therefore, the color of crows is disgusting, forming the concept that crows are bad omens. In the superstition of "left eye jumps to wealth, right eye jumps to disaster", the reason is that people's understanding of "left" and "right" is based on traditional Chinese religious beliefs. The traditional Chinese concept of the universe of the world is divided into two categories of yin and yang: the sky for the yang, the ground for the yin; male for the yang, female for the yin; the south for the yang, north for the yin; left for the yang, right for the yin; life for the yang, death for the yin; the sun for the yang, the moon for the yin; and so on. Although yang and yin*** together constitute the world, on the whole, yang is often associated with light and life, while yin is often associated with darkness and death. Thus, the concept of "left is up, right is down" is formed, and the left eye jumps as a matter of course to become an auspicious omen, and the right eye is also false as a bad omen. Therefore, the superstitious concepts and behaviors are closely related to religious beliefs.
