When is the arch or hidden arch in the eight characters?

The eight-legged ground support is like the four feet of a table, supporting the whole desktop. If four legs are enclosed, it is a circle, then the four-legged earthly branch secretly contains twelve earthly branches, that is to say, in addition to the "visible" four-legged earthly branch, in fact, human life is also "hidden" with other earthly branches. Hidden archways and hidden meetings have a great influence on people's lives. Almost all life levels, such as wealth, poverty, longevity, number of six relatives, education level, beauty and ugliness, are calculated by hidden archways and hidden societies.
