However, what does it mean to work year after year? Anyone who knows, please help explain, thank you very much?

However, it may mean that there is a relationship between the years of Wu and Ren in a specific year or month. This statement has no scientific basis and may be a superstition.

It should be noted that in astrological fortune-telling, heavenly stems and earthly branches's relationship is only used as a reference, and it cannot completely determine a person's fate. A person's fate is influenced by many factors, including but not limited to family background, educational experience, career choice, health status and so on. Therefore, don't be overly superstitious about eight-character fortune telling, but seek happiness and success in your own efforts and practical actions.
