Published: 2026/01/17   Author: jinqi   Source: network

In traditional Chinese astrology, the analysis of the eight characters (Ba Zi) is crucial for predicting an individual's fortune. This article will delve into the astrological implications of having a "Bi Yin" (secondary seal) in the year pillar and "Qi Sha" (seven kill) in the month pillar, revealing their impact on personal character, health, career, and family relationships.

Basic Concept of Bi Yin

Bi Yin is an important concept in Chinese folk Ba Zi astrology, referring to the same-sex element that is produced by the individual's five elements. It is also known as "Tun Tan Sha" (swallowing and devouring demon), and it is considered the seven kill of the Food God (Shi Shen). Therefore, it is also called "Reverse Food." Bi Yin is the day stem that shares the same yin-yang attribute with the day master. Understanding the basic meaning of Bi Yin is a prerequisite for analyzing its role in the four pillars.

Effects of Bi Yin in the Year Pillar

If Bi Yin is present in the year pillar, it usually indicates a distant relationship with one's father or emotional disharmony. If there is a conflict or mutual destruction between the year and month pillars, and the day master is weak, it may indicate a potential for harm to grandparents and father. On the contrary, if the day master is strong, and there are many or strong secondary wealth elements, it may indicate a longer life for the father.

Characteristics of Bi Yin in the Month Pillar

The presence of Bi Yin in the month pillar indicates that the individual is intelligent, capable, and multi-talented, but may have a peculiar, reclusive, and stubborn personality. These people have a strong sense of self-respect and competitiveness, which makes them prone to making enemies and suffering from hidden damage. When Bi Yin in the month stem meets Qi Sha in the month branch, it can lead to excessive suspicion and competitiveness. If Bi Yin meets Bi Cai (secondary wealth), the person tends to be cheerful and suitable for starting from scratch, preferably in a different place. If Bi Yin meets Shi Shen (food god), it may lead to poverty and misfortune. If Bi Yin meets conflict or destruction, it may indicate unexpected dangers. If Bi Yin meets Zheng Yin (primary seal), it can turn evil into good, as a benevolent deity controls an evil one. If Bi Yin meets Guan Sha (officer kill), it may result in frequent success and failure in one's career. If Bi Yin meets Shang Guan (伤官, injury official), it may indicate abundant wealth throughout life.

Effects of Bi Yin in Other Pillars

If Bi Yin is present in the day pillar, it may indicate poor marriage. Men may struggle to find a virtuous wife, and women may have difficulty marrying a suitable partner, typically finding a match after the age of 30. If the day pillar has Bi Yin and Shi Shen, it may lead to poverty. If the day pillar has Bi Yin and conflict or mutual destruction, it may indicate unforeseen disasters. If the day pillar has Bi Yin, Shi Shen, and a strong day master, it may bring good fortune; if wealth is strong, there may be opportunities for wealth. If the day pillar has Bi Yin, Shi Shen, and a weak day master, it may lead to poverty. If Bi Yin is present in the hour pillar, it may indicate that the first child is a daughter, and later generations may not be reliable or ungrateful. If Bi Yin meets Yang Reng (Yang刃, yang blade), children may be difficult to raise, with many illnesses or injuries. If Bi Yin meets Shi Shen, it may indicate loneliness in old age. If Bi Yin meets Shang Guan, it may indicate a life of comfort and abundance.

Through an in-depth analysis of Bi Yin in the year and month pillars with Qi Sha, we can gain a more comprehensive understanding of how this astrological phenomenon affects various aspects of personal life. The position and combination of Bi Yin not only relate to an individual's character and fate but may also influence health, career, and family relationships. Understanding this information helps us make wiser decisions in life to avoid harm and seek benefits.
