The eight characters cannot be separated from the pattern, and the pattern cannot be separated from the prosperity and decline of the five elements, especially the prosperity and decline of the day master. In addition to the previously mentioned order, root, and qi, there is another reference point for the prosperity and decline of the five elements, which is the twelve long lives. It describes the state of things in development and change. In fact, it is the same as the Book of Changes. Each hexagram of the Book of Changes has six lines, from the first line to the upper line, which is the change process of each hexagram. Extended to the year, the Book of Changes has twelve message hexagrams, from the Fu hexagram to the Kun hexagram, representing the changes of the twelve months of the year. In fact, it can also be discussed as the development and change of all things in a year. So how to use the twelve long lives? What is the principle behind it? The twelve long lives are to assist in judging the prosperity and decline of the day master, and can also be understood as the qi of the earth. They are: long life, bathing, crown, official, emperor, decline, disease, death, tomb, extinction, fetus, and nourishment. Among them, Changsheng to Diwang means that the vitality is strong, which indirectly expresses that the day master has the support of the earth to display his talents; while Shuai to Yang means that the vitality is weak, which means that the day master should not be too hard in life and should be conservative. To describe it from our own perspective, it is actually a life of "birth, aging, illness and death", which can also be used to describe the whole process of the generation, development, decline and extinction of things. Corresponding to the life process of a person: Changsheng is birth, Muyu is a child, Guandai is an adult, Linguan is the development of things, Diwang is the peak of things, Shuai is the decline of things, Bing is the trouble of things, Si is the disaster of things, Mu is the hardship of things, Jue is the despair of things, Tai is the gestation of life, and Yang is the birth of life. The meanings are explained below: Changsheng: contains the meanings of birth, growth, backing, starting point, and originality. Changsheng is the image of growth, the beginning of all things, and has the ability to create and open up. Therefore, when you meet the year of Changsheng, your thinking will be very active and you will easily have new ideas and thoughts. But the disadvantage is that the foundation is unstable just after birth. If it is too much punished, it is easy to be depressed. Therefore, if Changsheng is attacked, it will bring failure because of its own rash actions. Bathing: Contains the meanings of nakedness, bathing, entering water, corruption, disadvantage, exposure, etc. The place of bathing is often called a defeated place, so it contains disadvantageous elements. Of course, bathing and changing clothes also contain the meaning of bidding farewell to the old and welcoming the new. Bathing is the rising stage of the five elements. This kind of air is easily absorbed by the ground. Because it is relatively tender and has no resistance, it is easy to be bewitched. It is easy to do things with bathing on intuition, and men are prone to emotional entanglements with the opposite sex. Guandai: Contains the meanings of growing up, upgrading, joining the army, wearing a hat, packaging, decoration, covering, etc. Guan is actually a hat. In ancient times, Guandai was a coming-of-age ceremony for those who turned 20. It is the main event, a small honor in career, a small success, and a Guandai person has a strong self-esteem and a good face. Women in Guandai have a masculine spirit and like to instruct others, especially their husbands. Linguan: Contains the meanings of being an official, within the system, state-owned, government, and civil servants. Guan means salary, which can also be understood as promotion and wealth, or starting a business and becoming a boss to make money. People whose horoscopes contain Linguan are relatively independent, have a spirit of not admitting defeat, dare to accept failure and setbacks, and have the courage to create. Diwang: Contains the meanings of extreme, highest point, limit, climax, rapid rise, etc. However, Diwang is in the stage of extremes, so it implies some decline. The flying dragon in the sky in the Qian hexagram is Diwang, and the following is Kanglongyouhui. Diwang means that one can do things easily, has full energy, and is mature physically and mentally. The old saying goes: It is not suitable for the time branch to be in Diwang. In fact, it means that old people are afraid of Diwang and less afraid of decline. When people are old, they are prone to rebellion because they need to be restrained and quiet in old age, and their qi should be hidden, not showing off. Decline: Contains the meaning of decline, withering, fatigue, weakness, and decline. Decline means the decline of Qi, which is the decline after the peak. It mainly means the lack of enterprising spirit, patience and confidence. The main manifestation of life is relatively conservative, not showing off, and being easily satisfied, so it is easy to be neither high nor low, and dare not resist, and compromise. Disease: It contains the meanings of disease, disgust, disease, hatred, problem, trouble, etc. Disease is actually a kind of Qi of things that violates the right way, and an unhealthy phenomenon occurs. The Qi is relatively weak and empty. The day master sitting in the sick place is easy to be tied down by external things, thinking too much in the mind and easily miss opportunities, and people are prone to be sensitive and suspicious, especially Yin day stems, the performance is more obvious. Death: It contains the meanings of death, rigidity, stubbornness, clumsiness, inability to think, and lifelessness. The day master's dying place is different from death. It mainly refers to the fact that he is more rigid and stubborn in his career and dealing with people. He will not turn back until he hits the wall. But the good thing is that he is relatively stable and will not be too fickle. But if a woman has two dead earthly branches, it is easy to cause trouble in marriage and love. Tomb: Contains the meanings of chaos, distress, restriction, constraint, collection, and accommodation. Tomb is the destination of the five elements, and also contains the meaning of avoidance. Therefore, the day master is likely to have bad luck when encountering a tomb. When encountering a tomb in childhood, the family background is usually average, or the relationship with relatives is not deep. When encountering a tomb in middle age, it affects the state of marriage, the mood is not open, the two sides do not communicate, and there are more disputes. Absolute: Contains the meanings of desperate, despair, dead heart, ruthless, and extremely disappointed. Absolute means the severance or isolation of qi, the intersection of two types of things, and the dividing line between yin and yang. Absolute is the process of turning around, which is quiet and natural, without sound or sound. Therefore, the day master sitting in Absolute is often a very low-key person, who is cautious in doing things, likes some relatively easy industries, and is not suitable for being a leader. Fetus: Contains the meanings of prototype, plan, innate, nature, starting point, etc. Fetus is the re-germination of things, just like a fetus in the belly, who likes to keep quiet and does not like to move the fetal qi. Therefore, the fetus in the year indicates weak vitality and poor physical fitness when he was a child. If there are too many fetuses in the eight characters, the day master prefers a free and quiet career, does not like to be ostentatious, and does not have great ambitions. Yang: contains the meanings of adoption, raising, relying on, nourishing, and worrying. Yang refers to the birth of a child, which needs to be cultivated and begins to have a sense of heaven and earth. Yang in the year pillar will get help from parents and ancestors, or be able to integrate the family business. Yang in the day pillar is not good for the relationship between husband and wife, and Yang in the hour pillar means old age, a long life of leisure and stability.
