What do you mean by eight characters and five elements?

The horoscope consists of eight characters, representing the year, month, day and time of your birth. It's called four pillars. There are four pillars in heaven and four pillars in earth. Heavenly stems and earthly branches in a column. They are all called eight characters, and the earthly branch is 12 earthly branch. For example, the moon column is the second month (the month is the most important), the sky is the second, and the earth is the sea. We only saw a heavenly stem and a earthly branch, but there is something hidden in the earthly branch, and the hidden thing is called Tibetan Yuan. For example, Ren and Jia are hidden in the sea of this earthly branch. That is to say, the sea of the earth contains nonyl and armour. Hai is water, and ren is also water, so ren is the original gas of Hai, while A is not water but residual gas, also called miscellaneous gas. If this original gas ring appears on other columns, such as a year that is not noon on the annual column, call it out. It is also the main basis for choosing patterns. I explained it to you in a simple way and language. I hope it helps you.
