What does Zhang Nian and Zhang Nian Wealth mean?

The five elements are happy and jealous.

In ancient China, the year, month, and day were recorded with 10 heavenly stems and 12 earthly branches, which were called four pillars. Each pillar has two characters, one is heavenly stem, the other is earthly branch, a total of eight characters, so it is called eight characters. But in the past, it was only used to record the days, and there was no so-called fortune telling. After a long time, some people collected these materials together and gradually found that there seemed to be a rule to follow before they developed into eight-character fortune telling.

During the Spring and Autumn Period and the Warring States Period, Zou Yan brought the world outlook of the Five Elements into everything, and the theory of Yin and Yang of the Five Elements began to develop. These eight words have also been endowed with different attributes of five elements. The five elements are what elements they like, what elements they hate, and more elements they like, which can certainly help you, and vice versa. That's about it.
