For example, the Japanese branch of the figure of eight is Xu, which contains dried fruits of bentonite, bentonite and bentonite, but there is no bentonite or bentonite on the dried fruits of the figure of eight, so it is airtight. In other words, the branches hidden in the ground are not exposed in the sky.
In terms of personality,
Tiangan represents the character of appearance.
The earthly branch represents the original character.
If the heavenly stems hidden in the earthly branches represent potential personality: if Ding Huo represents your talent, and your (D) talent is hidden in the soil, and the heavenly stems (appearance) do not show Ding Huo (talent), then your talent is not seen, and you don't know that you have a talent, because this talent is potential and needs time to play. When you meet an auspicious year, if you work for four years, then this kind of work is called "eight-character through work". If Ding Huo does it, it means that you have been seen, so you may find yourself talented or promoted during this time.
