Ba-Zi (The Eight Characters of Destiny) is an ancient Chinese system of astrological analysis that describes a person's life through the elements of energy present at the moment of their birth.
The four pillars that determine a person's destiny: the year, month, day, and hour of birth.
It is said that Ba-Zi is not so much a fatalistic prediction as it is a tool for understanding a person's energy, allowing one to synchronize with nature and make more conscious decisions.
