Is there a scientific basis for fortune telling?

The theory of "421 yuan" is a part of Yuan Tiangang's theory of "weighing bones", which is based on the theory of inferring the year of birth and the life span of the owner.

Yuan Tiangang's theory of calling bones is superstitious and has no scientific basis, and its accuracy has not been scientifically confirmed. Therefore, it is impossible to judge whether the name of 42 1 yuan is correct.

Scientifically speaking, people's life span is influenced by many factors, including heredity, environment, lifestyle, health status and so on. Therefore, it is impossible to accurately predict people's life span through a simple theory of weighing bones.

In a word, 42 1 yuan is a superstitious theory, and its accuracy has no scientific basis, so it can not be used as a standard to judge people's life span.
