What is the meaning of "two mountains and one column" in geomantic omen? Can you see the schematic?

This is the "Bijia Mountain" commonly used in Feng Shui. Generally speaking, it refers to the mountain shape that appears in front. The so-called "one bar" means that there is a brush on Bijia Mountain, which means that this mountain is really Bijia Mountain, because some fake Bijia Mountain that looks like Bijia Mountain but has no brush on it is only real. With this Bijiashan, the younger generation can generally be civil servants. If it is a standard mountain, the younger generation can generally be an official like a military commander.
