Is it necessary to turn Lao Yang in hexagrams into Shaoyin and Laoyin into Shaoyang?

Is it divination with three copper coins? All three are heads, that is, they are actually yin (extremes meet); Conversely, all three are tails, that is, old yin, and old yin is actually yang. The one with or without yin is dynamic, and if there is yin at the same time, it is dynamic (yang takes the initiative and yin dominates static); If they are all old yin, it is that the old yin of the external divination is dynamic (external movement, internal static).
