Five Algorithms

Meihua Yijing (Plum Blossom Numerology) was founded by Shao Yong (posthumously Shao Kangjie), a renowned Song Dynasty philosopher. Legend has it that Shao comprehended the way of deciphering cosmic patterns by observing two birds fighting on a plum tree, hence the name "Plum Blossom" (Meihua). Rooted in the image-number (Xiang-Shu) school of the I Ching, it emphasizes "observing phenomena to derive images, using images to infer numbers, and using numbers to illuminate principles"—a system centered on the correspondence between heaven and humanity.

A hexagram is cast using the time of inquiry or a random number. The upper trigram (Heaven) and lower trigram (Earth) combine to form one of the 64 hexagrams. A moving line (Dong-Yao) generates a transformed hexagram (future trend), while intersecting trigrams (Hu-Gua) reveal hidden relationships. The core analysis is "Ti-Yong" (Body vs. Application): the Body hexagram represents the inquirer, and the Application hexagram represents the matter in question. Auspiciousness is determined by the generation and restriction cycles of the Five Elements, combined with the month-command strength and mutual hexagram relationships.

Bazi (Four Pillars of Destiny) originated from ancient Chinese sexagenary (Ganzhi) chronology. Li Xuzhong of the Tang Dynasty pioneered the three-pillar method using year, month, and day. Later, Xu Ziping of the Song Dynasty added the hour pillar, forming the complete four-pillar system—each pillar consists of one Heavenly Stem and one Earthly Branch, totaling eight characters (Bazi). After a millennium of practical refinement, alongside Ziwei Doushu, Bazi stands as one of the two great pillars of Chinese destiny analysis, built on the rigorous framework of Yin-Yang and the Five Elements.

The birth year, month, day, and hour are mapped to four pillars, each containing a Heavenly Stem and Earthly Branch. The Heavenly Stem of the Day Pillar (Day Master / Rìzhǔ) represents the individual. The other seven characters interact with the Day Master through the Five Elements generation/restriction cycles. The Ten Gods (Shíshén)—Zhengguan, Qisha, Zhengyin, Pianyin, Bijian, Jiecai, Shishen, Shangguan, Zhengcai, Piancai—and their configurations, along with Nayin Five Elements, Xunkong (Void), and Da-Yun (Major Cycles) / Liunian (Yearly Fortune), construct a comprehensive portrait of innate endowment, character, career, wealth, marriage, and life trajectory. Each Da-Yun lasts 10 years, and each Liunian brings annual variations.

Ziwei Doushu (Purple Star Astrology) is traditionally attributed to Chen Tuan (also known as Chen Xiyi), a legendary Taoist master of the Song Dynasty. It was later compiled into the "Complete Book of Ziwei Doushu" by Luo Hongxian in the Ming Dynasty. Named after the Ziwei Star (Polaris), which symbolizes the Emperor star surrounded by attending stars, the system constructs a 12-palace life chart. Alongside Bazi, it is hailed as one of the two supreme arts of Chinese destiny analysis, flourishing in both imperial courts and folk traditions through the Ming and Qing Dynasties.

Based on birth data, the system first determines the Mingong (Fate Palace) and the Five-Element Bureau. The 14 Major Stars (including Ziwei, Tianji, Taiyang, Wuqu, Tianfu, etc.) are then placed into the 12 palaces according to precise star-placement rules. Additionally, 13 Auxiliary Stars (Lu Cun, Tianma, Wenchang, Wenqu, etc.) are configurated. The Four Transformations (Huà Lù / Huà Quán / Huà Kē / Huà Jì) fly across palaces based on the Heavenly Stem of the birth year. By analyzing the star combinations in each of the 12 palaces—Mingong (self), Siblings, Spouse, Children, Wealth, Health, Travel, Friends, Career, Property, Fortune, and Parents—and the major/minor fortune cycles, a comprehensive life chart is revealed.

Western astrology traces its origins to ancient Babylonia (~2000 BCE), where priest-astronomers began systematically recording correlations between celestial movements and earthly events. The system was codified by Claudius Ptolemy in his "Tetrabiblos" during the Greco-Roman period (~150 CE), which became the cornerstone of Western astrological theory. It later flourished in the Arab world during the Middle Ages, and experienced a major revival in European courts during the Renaissance. Modern astrology integrates depth psychology (Jungian archetypes) and humanistic philosophy, shifting from "predicting fate" to "understanding the self."

Based on the sky map (natal chart) at the exact moment of birth, the system calculates the precise positions of the ten planets (including the Sun and Moon) along the ecliptic, their house placements (using the Placidus house system), and the aspect angles between planets (conjunction, sextile, square, trine, opposition, etc.). By synthesizing planetary placements by sign and house, elemental balance, modality, and aspect harmony/tension, the chart reveals personality traits, talent potential, emotional patterns, and career direction. Special sky phenomena such as planetary retrogrades and the Lunar Nodes provide deeper karmic and psychological insights.

Transit & Progression is not a single classical art but a modern engineering achievement that integrates multiple predictive traditions. The system blends three mainstream forecasting methods: Transit (rooted in modern Western astrology) analyzes current planetary positions in relation to the natal chart; Secondary Progression was systematized by the British astrologer Placidus de Titus in the 17th century, using the "one day = one year" symbolic correspondence; Solar Arc Direction was refined by the German Hamburg School in the early 20th century, advancing all points by the Sun's annual motion. The three methods complement each other, forming a multi-dimensional time-axis prediction system.

Transit: calculates the real-time positions of transiting planets and the aspects they form with natal planets and sensitive points, determining the direction and intensity of current cosmic energy influences. Secondary Progression: the sky on each day after birth corresponds to one year of life development; observing progressed planets (especially the progressed Moon) interacting with the natal chart reveals deep psychological evolution and inner/outer turning points. Solar Arc: all planets and sensitive points are advanced by the same arc as the Sun's actual movement (~1° per year); when a solar-arc point forms an exact aspect (within ~1°) with a natal point, it typically signals a significant life event. The three methods operate on different time granularities: Transit is day-level, Progression is year-level, and Solar Arc is year-to-month-level.
