Park Gun-wook is The Oak Horse

This is the day pillar only. It is fixed by the calendar date of birth, which is public — so it can be calculated with confidence. The hour pillar cannot: Park Gun-wook's birth time is not published, and guessing at one would produce a chart that looks precise and is not.

What the day pillar says is character rather than circumstance.

The day pillar is read as two halves. The stem is what a person is made of; the branch is what they are standing on. Here the stem is yang Wood — the wood that does not bend to be liked — growth with a direction already chosen, and a reluctance to be pruned by anyone else's hand.

The branch is the Horse: forward ground — a footing that moves toward things, and only later asks whether it meant to.

Both halves push outward, which makes this a chart with very little brake on it. The strength is that nothing has to be talked into starting. The cost is that there is nobody inside the chart arguing for waiting.
