Any practice that requires submitting your birth date and place of birth for calculation is fortune telling. There are four types of fortune telling in human history: astrology, Bazi (Four Pillars of Destiny), Zi Wei Dou Shu (Purple Star Astrology), and the Anthropomorphic Graph (which only appeared in 1987). The content derived from these four methods differs, much like an orange: a cross-section, a vertical slice, and peeling by hand all reveal different appearances. The common thread is that fortune telling calculates a person's personality "type," their aptitude "inclinations," what they consider important or "correct," and even their thought patterns. Another aspect is "luck." As people grow, their state of mind and attitude change according to predictions under different major cycles and annual cycles. "In our familiar social operating model," "for the middle 70% of ordinary people," fortune telling can predict quite accurately what career you are suited for, the approximate ups and downs of your life, what kind of spouse you will marry, and even how many children you will have. If the social operating model changes dramatically every ten years (and nearly half of society ignores these changes), old jobs are eliminated and new ones emerge, and the rules of the game change every ten years... For those avant-garde, adventurous, and highly mobile niche individuals, it's incredibly difficult to predict how the categories, tendencies, and values predicted by fortune-telling will manifest in their lives. Therefore, we can only view fortune-telling as a skill, much like a scientific director at an observatory—doing their best, but unable to guarantee accuracy. The more unique a person is, the harder their fate is to predict accurately. Not to mention whether life is predetermined.
