From childhood to youth, one can wear clothes and hats, appearing dignified and impressive; new things also enter a splendid stage. "Guan" means hat, and "dai" refers to ancient accessories. "Guan Dai" is also the ancient coming-of-age ceremony for men and women at the age of twenty, indicating adulthood. Guan Dai signifies celebration, with achievements in matters or careers being a cause for joy. When it appears in one's destiny or life, it signifies auspiciousness and minor nobility. When it appears in a time limit, it indicates small achievements and financial gains, drawing from the metaphor of minor accomplishments in men's and women's coming-of-age ceremonies.

Generally speaking, those whose Ba Zi (Eight Characters) have their destiny seated in Guan Dai tend to have an overly strong sense of self-esteem, enjoy dominating others, and dislike being dominated, making it easy to make enemies. For women, it indicates a masculine demeanor. Such women like to direct their husbands but take great care of their own families. There is also a saying: "In the village of Guan Dai brothers, even if separated by hills, though living under the same roof, the fires burn at both ends." This is just a tendency; please use discretion when applying it to avoid mistakes, as the study of Yi (易) is ever-changing and should not be rigidly applied.
