Plum Blossom Divination, created by Shao Yong of the Song Dynasty, uses the Eight Trigrams to interpret the numbers of heaven and earth. The Lifetime Divination, in particular, can reveal a person's life destiny. Its method is based on the Six Relatives: Official, Parents, Siblings, Children, and Spouse/Wealth, each governing fortune and misfortune. The current discussion of what is suitable and unsuitable for those working within the system and those starting their own businesses originates from the subtle principles of the I Ching. Ancient I Ching texts such as the *Zhouyi* and *Plum Blossom Divination*, recorded in the *Siku Quanshu* (Complete Library of the Four Treasuries), all provide evidence for this. In the Lifetime Divination, the interactions of the Six Relatives reflect one's life. Official represents career and power; Eating God/Hurting Officer (Children) represents talent and artistic expression; Seal (Parents) represents literature and knowledge; and Wealth represents wealth and resources. The auspiciousness or inauspiciousness of the hexagram changes according to one's circumstances. For those working within the system, seeking stability and advancement, official rank and salary are paramount. Meeting an official is auspicious, as a strong Official Star indicates a smooth career path, as the *Plum Blossom Divination* states: "When the Official Star is in a favorable position, fame and success are attainable." A prominent official position indicates upright conduct and support from superiors and subordinates. Those who benefit from the presence of the Eating God and Hurting Officer stars will find their talents and achievements evident, gaining recognition within the system. As the ancient texts say, "The Eating God controls the Killing Star, possessing both literary and martial talents." Those who benefit from the presence of the Seal star will find their academic and administrative work smooth, promotions and assessments easier, as the Seal star represents protection and benefits from elders or policy support. Those who do not benefit from the presence of Wealth will find that excessive Wealth can weaken the Seal star, easily leading to greed and tarnishing their reputation for integrity. The Complete Library of the Four Treasuries (Siku Quanshu) states in the section on numerology, "When the Wealth Star breaks the Seal star, official troubles are hidden." Within the system, integrity is paramount; exposed wealth invites trouble, hence abundant Wealth in the hexagram is not auspicious. Entrepreneurs, however, are different. They seek wealth and change, valuing freedom. Those who benefit from the presence of the Seal star will find it nourishing, their knowledge and experience forming the foundation for entrepreneurship, and they will receive protection from benefactors, overcoming obstacles. As the hexagram in the Book of Changes says, "Mountain Thunder Yi, seeking sustenance." A strong Seal star indicates a stable foundation. Those who benefit from the presence of Wealth will find abundant Wealth, directly impacting success or failure; abundant Wealth in the hexagram symbolizes market opportunities. Ancient texts state, "When the wealth palace moves, merchants will benefit." It is unfavorable to encounter officials, as the official ghost (官鬼) restrains the self, signifying constraint and pressure. Entrepreneurs should be wary of legal troubles or policy changes causing difficulties. The Complete Library of the Four Treasuries (四庫全書), a comprehensive collection of Yi Jing (易經) texts, includes the section "The Orthodox Principles of Divination" (卜筮正宗), which states, "When the official ghost disturbs the situation, plans will face many obstacles." Entrepreneurs need flexibility; a heavy official position will restrict their actions, and may even lead to lawsuits. Therefore, avoiding such situations is best. These two considerations are not arbitrary but rooted in the principles of Yin and Yang. Those within the system are like still water, needing the official seal (官印) and food/injury stars (食傷) to maintain balance; entrepreneurs are like flowing water, needing the seal (印) and wealth stars (財) to facilitate their progress. The subtlety of Yi Jing lies in its adaptability; the interpretation of a hexagram throughout one's life should also be tailored to the individual. The ancient texts recorded in the Complete Library of the Four Treasuries all elucidate this principle, conforming to the principle of harmony between Heaven and Man. Readers who study it deeply will understand its correctness; it is nothing more than assessing the situation and carefully examining the hexagrams.
