======Eight Characters ======
Four Pillars of Destiny (Four Pillars of Destiny) is a long-standing ancient Chinese numerology technique, originating in the Tang and Song dynasties and perfected in the Ming and Qing dynasties. It calculates a person's birth chart based on their year, month, day, and time of birth, typically accurate to the hour (i.e., within two hours). Because ancient people lacked a unified clock system, this time was generally considered local time, so calibration with local time (true solar time) is often necessary.

The analysis of Eight Characters encompasses various schools of thought, including the structure, the Ten Gods, climate adjustment, and the evil spirits. Predictions are made based on the strength and weakness of the useful gods and their performance. It is typically used to determine long-term issues related to a person, rather than specific, short-term considerations. Examples include "what career is suitable," "what characteristics should a partner possess," and "what health issues should be considered." Traditional categories include "wife, wealth, children, fortune, and longevity," encompassing aspects of love, wealth, family, career (or academics), and health.

The day stem in the original Eight Characters chart is called the Day Master and represents the person being analyzed. The other stems and branches represent external circumstances, with the lunar month being particularly important. The lunar month outlines a horoscope, reflecting the month of a person's birth, whether it was sweltering or freezing cold, setting the tone for the overall environment. Some blind fortune-telling schools also consider the day and hour as the home, and the year and month as the exterior.

The annual luck in the Eight Characters is used to predict the timing of events, such as "Which year will I get married?" or "What major luck will bring prosperity?" A major luck is a unit of time, lasting ten years. It is a neutral term, with both good and bad major luck. The stems and branches of a major luck reflect the overall trajectory of that major luck. Each year in the major luck is called the "liu nian," also known as the Tai Sui or the Sui Jun, the ruler of the year's forces. When analyzing a particular year, it's generally necessary to combine the original horoscope and the annual luck for a comprehensive analysis. Years without a major luck stem and branch before the start of the Eight Characters are called "minor luck."

If you're asking about the short-term trajectory of a specific event, especially a series of parallel events, using hexagrams is recommended. For example, "Should I work at Company A or Company B?" or "Did my recent TOEFL exam go well?"
=====Liu Yao Na Jia======
Liu Yao prediction is a divination technique with a long history, originating from the Na Jia system of the Jingfang area of the Western Han Dynasty. It uses information such as the Six Gods and Six Relatives in the hexagram, combined with the time of the divination, to analyze the strength and weakness of the God of Use in the hexagram to make predictions.
Liu Yao predictions can cover a range of areas, including career, relationships, studies, wealth, and health, generally covering events within the next six months to a year. It's often used to predict the specific direction of an event, such as "Will I do well on my exam next month?" or "How does the boy I'm secretly in love with feel about me?" Because it relies on post-natal observation, the results can vary depending on the observation itself.
Divination typically involves a separate divination, meaning a single hexagram is drawn for each question (multiple divinations from the same hexagram are more demanding). For related but distinct questions, it's recommended to perform two separate divinations. For example, questions like "How does the boy I'm secretly in love with feel about me" and "What should I do to get him?" are logically related, but they are different questions. It's recommended to cast multiple hexagrams during the same conversation.

It's recommended to ask the same question no more than once a day, and the first time will be the correct answer.

If it involves a series of parallel events, it's recommended to cast multiple hexagrams. For example, "Is it better for me to work at Company A or Company B?" It's recommended to cast hexagrams at both Company A and Company B, comparing the differences and advantages and disadvantages.

If you're asking about your long-term prospects, such as how your relationship will be or when you'll become wealthy, it's recommended to consult with your Bazi.

=====Combination Chart =======
Combination charts typically compare the compatibility between two natal charts. Most numerology schools utilize combination chart techniques, including Bazi, astrology, and Zi Wei Dou Shu. However, different schools of thought have different emphases. Bazi, by contrast, focuses more on objective results, stability, and similarity in structure and level. Astrology focuses more on subjective experiences, such as how each partner perceives the other, how they interact, and how the relationship evolves over time.

Combinations differ in different contexts, such as those for marriage, friendship, and collaboration. Users should conduct specialized synastry analysis tailored to their specific context.

Combination results reflect the compatibility between individuals of a specific type and do not reflect the fateful relationships between specific individuals.
