What does the Feng Shui saying "two mountains sandwiching a bar" mean? Can you see the schematic?

This is the "Beacon Hill" often used in Feng Shui. Generally speaking, it refers to the shape of a mountain that appears toward the front. The so-called "one bar" refers to a writing brush standing on Bijia Mountain, which means that this mountain is real Bijia Mountain, because some are similar to Bijia Mountain but do not have a writing brush on it, which are fake. Beacon Mountain is real only on Beacon Mountain. For those in Bijia Mountain, the next generation will generally be able to produce officials such as civil servants. If it is Jingqi Mountain, the younger generation can generally produce officials such as military generals.
