What is a grave and how to understand its meaning?

In the numerology of Zhouyi, many terms or symbol names are composed of two words of unity of opposites, such as "official ghost", "official ghost" is the white road for yang, and "ghost" is the underworld for yin. How could the ancients combine this irreconcilable "official" and "ghost" as a special term? Did the ancients make a mistake? Of course not! The opposition between "official" and "ghost" is good, but they are also unified, and under certain conditions, "official" and "ghost" can be transformed into each other.

In fact, the same is true of "tomb cellar", and "tomb cellar" and "vault" are also the unity of opposites. Generally speaking, the numerology meaning of "tomb pit" means returning home, seclusion, intersection, restraint and so on. "Graveyard" represents warehouses, walls, containers, graves, hospitals, cells, reservoirs, stoves and so on. According to the principle that "decay is the grave and prosperity is the reservoir", we can use the "grave" to represent the image of negative energy, while the "reservoir" to represent the image of positive energy. Even so, we can't directly use the tomb to judge good or bad luck. For example, although the "tomb" represents a negative energy image, it does not necessarily mean that the fate of the Lord is fierce, because if it is hatred for the gods, it will lead to the fate of the Lord.
