In the study of fate, the major luck (大运) is one of the important factors influencing a person's destiny. The "Bi Yin" major luck, as one type of it, has a profound impact on an individual. This article will delve into the characteristics of the Bi Yin major luck and its influence on personal fortune, helping readers better understand this concept in fate studies.

Rules of Major Luck
The major luck operates mainly in two ways: one is the cycle of the ten heavenly stems, including the same sex brother, robbery, food god, injury, secondary wealth, main wealth, secondary official, main official, secondary print, and main print; the other is the cycle of main print, secondary print, main official, secondary official, main wealth, secondary wealth, injury, food god, robbery, same sex brother, and main print. Among these major lucks, the main print, secondary print, same sex brother, and robbery belong to the supportive type, while the main official, secondary official, main wealth, secondary wealth, injury, and food god belong to the restraining type. Depending on the strength or weakness of an individual's four pillars of destiny, the chosen use god and the forbidden god will vary accordingly.
Strength and Weakness of the Four Pillars and Selection of Major Luck
The strength or weakness of the four pillars determines the use god and forbidden god in the major luck. For those with strong four pillars, a restraining major luck is needed — that is, the restraining ones are the use god, and the supportive ones are the forbidden god. On the contrary, for those with weak four pillars, a supportive major luck is needed — that is, the supportive ones are the use god, and the restraining ones are the forbidden god. The cycle of major luck lasts for ten years. Assuming a lifespan of 80 years, a person can experience up to eight major luck periods.
Characteristics of the Bi Yin Major Luck
The Bi Yin major luck is one of the supportive types. For individuals with weak four pillars, the Bi Yin major luck is a favorable period that provides support and assistance. However, for those with strong four pillars, the Bi Yin major luck may bring some challenges, as it might over-enhance certain aspects, leading to imbalance. The impact of the Bi Yin major luck varies from person to person and requires analysis based on the specific conditions of each individual's four pillars.
Diversity of Major Luck
The operation of major luck is diverse, covering different starting points (different auspicious stars) and two different directions, totaling 20 different operational methods. These major luck methods include various combinations of restraining and supportive types, affecting everyone's fortune at different stages of life.

As an important concept in the study of fate, the Bi Yin major luck has a profound impact on an individual's destiny. By understanding the rules and characteristics of major luck, we can better grasp the direction of our destiny. Since everyone's four pillars are different, the impact of major luck also varies. Therefore, gaining a deep understanding of the significance of the Bi Yin major luck helps us make wiser choices in life.
