6. Four-pillar prediction is a method to infer the good or ill luck of people through four pillars and eight characters (people used to call them "eight characters") with heavenly stems (namely, A, B, C and D) and earthly branches (Zi, Ugly, Yin and Mao).
Four-pillar forecasting is the most complete, comprehensive and accurate forecasting discipline at present. It can not only accurately measure my good fortune, promotion and wealth, but also determine the good fortune, wealth and poverty of my parents, children, brothers and sisters.
