The beginning of "Zaowei Lun" states: "The year of birth is the root, the month built is the seedling, the day governs management, determining the good and bad of middle age, the hour is the result, determining the glory and decline of old age." This sentence succinctly summarizes the importance of the four pillars and eight characters in fate theory.
In traditional fate theory, the balance of the five elements is a crucial concept. The so-called "When wood is abundant and meets metal, it is selected as a tool for pillars. When water is plentiful and encounters earth, it achieves the function of building embankments." This is a concrete manifestation of the principle of mutual generation and restriction of the five elements.
Fortune-tellers believe that by analyzing the five elements configuration in a person's birth date and time, the ups and downs of luck in various stages of life can be predicted. As stated in the document: "Those that are excessive and have no restraint are poor and lowly; those that are deficient and have no support suffer natural punishment." Only when the five elements are balanced can one achieve harmony and success in life.
In practical application, fortune-tellers will analyze factors such as the official star, wealth star, and seal ribbon in the eight characters in detail to comprehensively judge a person's career, wealth, health and other development trends.
