The assistant director watched me writing and sketching on the paper, not understanding what I was doing.
Sun Yuan couldn't make sense of it either.
"Mr. Chen, what are you doing?"
I didn't answer and continued my analysis.

The official ghost line was you metal. Metal could overcome wood, but a line in the hexagram had no power to generate or overcome the daily branch, so it was weak and restrained in relation to the day.
