What do you mean, an official has no roots?

That is, the eight characters have no roots.

Zhengguan (short for Zhengguan divination) refers to one of the stars in China Zhengguan divination, which is China's traditional horoscope thought and one of the ten gods in the horoscope divination. It turned out to be shamanism (shamanism here refers to shamanism in primitive society, not shamanism in Qing Dynasty), an astrological term used for divination.

The official's background.

In ancient times, people thought that a person's luck was like a watch. When the pointer went to different positions, people's fortune would have different performances. The official reflects the influence of a person's impression on the future in different periods and under different circumstances.

In ancient China, there was a saying that we should seek advantages and avoid disadvantages. Therefore, people in ancient China not only squatted, but also decided the sitting direction of their home according to the orientation of the gate. When we stand in the middle of the room and face the door, the orientation we face is "direction", while the orientation opposite to "direction" is "sitting". Regardless of the shape of the house, the orientation of sitting and facing must be relative.

For example, if the gate faces west, the house will sit east facing west. Eight directions correspond to eight kinds of divinatory symbols, namely, dry, watching, gen, earthquake, ten-day, calendar, Kun and right. The "sitting" position of a house determines what it belongs to. The door of the house faces east, sitting in the west, which is the "exchange" position of gossip. That house is an exchange.
