The System Architecture of Bazi Basics — Why These Must Be Memorized

Bazi Is Not Mysticism — It Is a Deductive System Built on a Precise Symbolic Framework

The foundation of bazi study is a rigorous symbolic system — the ten Heavenly Stems, the twelve Earthly Branches, Yin-Yang, the Five Elements, generation and control, combination and transformation, clash and punishment, flourishing and decline. Every bazi judgment is deduced from this symbolic system. If bazi is compared to a foreign language — the Heavenly Stems and Earthly Branches are the alphabet, Five Element generation and control is the grammar, the Sixty Jiazi is the vocabulary, and Luck Cycles and Annual Stars are tense changes. Without mastering this deepest layer of foundational knowledge, everything that follows — structures, Useful Gods, event reading — is built on sand. This article organizes the core knowledge points in bazi study that must be memorized — not 'understood well enough,' but 'known so fluently you can recite them with your eyes closed at any moment.'

Must-memorize checklist — ① Ten Heavenly Stems Yin-Yang, Five Elements + Directions (Jia Yi = Wood, Bing Ding = Fire, Wu Ji = Earth, Geng Xin = Metal, Ren Gui = Water; odd = Yang, even = Yin). ② Twelve Earthly Branches Five Elements + Zodiac + Month + Hour (Zi = Water / Rat / 11th month / 23-1h, Chou = Earth / Ox / 12th month / 1-3h…). ③ Five Element Generation and Control (Wood→Fire→Earth→Metal→Water sequential generation; Metal→Wood→Earth→Water→Fire interval control). ④ Five Stem Combinations (Jia-Ji = Earth, Yi-Geng = Metal, Bing-Xin = Water, Ding-Ren = Wood, Wu-Gui = Fire). ⑤ Branch Six Combinations, Three Combinations, Three Meetings, Six Clashes, Six Harms, Three Punishments. ⑥ Sixty Jiazi sequence table (Jia Zi 1 → Yi Chou 2 → … → Gui Hai 60). ⑦ Five Element Flourishing-Prosperous-Resting-Imprisoned-Dead (current-season = Flourishing, generates-current-season = Prosperous, generated-by-current-season = Resting, controlled-by-current-season = Dead, controls-current-season = Imprisoned). ⑧ Twelve Life Stages (Growth → Bath → Cap → Official → Peak → Decline → Sickness → Death → Tomb → Extinction → Embryo → Nurture). ⑨ Chart-casting formulas (Year Pillar = Start of Spring boundary; Month Pillar = solar-term boundary + Five Tiger Push; Day Pillar = check perpetual calendar; Hour Pillar = Five Rat Push). ⑩ Luck Cycle setup formula (Yang-year male & Yin-year female go forward; Yin-year male & Yang-year female go backward; 3 days = 1 year of starting age).

I. The Ten Heavenly Stems — Yin-Yang, Five Elements, Directions, and Basic Images

The Ten Heavenly Stems are the most fundamental symbolic units of bazi — the four stems in a chart (year stem, month stem, day stem, hour stem) all come from the Ten Heavenly Stems. The Ten Heavenly Stems in order: Jia (jiǎ), Yi (yǐ), Bing (bǐng), Ding (dīng), Wu (wù), Ji (jǐ), Geng (gēng), Xin (xīn), Ren (rén), Gui (guǐ). Yin-Yang attributes of the Ten Heavenly Stems — odd-numbered positions are Yang, even-numbered are Yin. Jia (Yang Wood), Yi (Yin Wood), Bing (Yang Fire), Ding (Yin Fire), Wu (Yang Earth), Ji (Yin Earth), Geng (Yang Metal), Xin (Yin Metal), Ren (Yang Water), Gui (Yin Water). Memory mnemonic: 'Jia-Yi Wood, Bing-Ding Fire, Wu-Ji Earth, Geng-Xin Metal, Ren-Gui Water — odd Yang, even Yin.' Directional assignments of the Ten Heavenly Stems — Jia-Yi = East (Wood), Bing-Ding = South (Fire), Wu-Ji = Center (Earth), Geng-Xin = West (Metal), Ren-Gui = North (Water). Basic images of the Ten Heavenly Stems — Jia Wood: towering tree, pillar of society, leadership quality, upright and unyielding. Yi Wood: vine and flower, flexible and adaptable, skilled at attachment, highly resilient. Bing Fire: solar fire, open and honorable, passionate and expressive, highly contagious. Ding Fire: lamp-candle fire, internally refined, persistent and focused, shining from within. Wu Earth: city-wall earth, thick and stable, honest and reliable, bearing all things. Ji Earth: garden-field earth, nourishing and moist, meticulous and inclusive, nurturing vitality. Geng Metal: axe blade metal, hard and sharp, decisive and daring, force of transformation. Xin Metal: pearl-jewel metal, exquisite and refined, perfection-seeking, sensitive and delicate. Ren Water: river-sea water, surging and flowing, wise and penetrating, grand in momentum. Gui Water: rain-dew water, silently nourishing, fine and penetrating, flexible to the deepest degree. The Five Stem Combinations pairings — Jia-Ji combine to Earth (central rectitude combination), Yi-Geng combine to Metal (righteousness combination), Bing-Xin combine to Water (authority combination), Ding-Ren combine to Wood (excess combination), Wu-Gui combine to Fire (merciless combination). The essence of the Five Combinations is Yin-Yang attraction — every combination pairs one Yang and one Yin stem, representing two forces drawn together by Yin-Yang complementarity, generating a new Five Element in the process.

II. The Twelve Earthly Branches — Five Elements, Zodiac, Month, Hour, and Hidden Stems

The Twelve Earthly Branches are more complex than the Heavenly Stems — they not only carry Yin-Yang and Five Element attributes but also correspond to zodiac animals, months, and hours; deeper still, each branch internally 'hides' hidden stems (one branch contains one to three Heavenly Stems). The Twelve Earthly Branches in order — Zi (zǐ), Chou (chǒu), Yin (yín), Mao (mǎo), Chen (chén), Si (sì), Wu (wǔ), Wei (wèi), Shen (shēn), You (yǒu), Xu (xū), Hai (hài). Five Elements and Yin-Yang of the Twelve Branches — Zi Water (Yang containing Yin), Chou Earth (Yin), Yin Wood (Yang), Mao Wood (Yin), Chen Earth (Yang), Si Fire (Yin containing Yang), Wu Fire (Yang), Wei Earth (Yin), Shen Metal (Yang), You Metal (Yin), Xu Earth (Yang), Hai Water (Yin). Branch Five Element grouping — Four Wood: Yin Mao. Four Fire: Si Wu. Four Metal: Shen You. Four Water: Hai Zi. Four Earth: Chen Xu Chou Wei. Zodiac correspondences — Zi = Rat, Chou = Ox, Yin = Tiger, Mao = Rabbit, Chen = Dragon, Si = Snake, Wu = Horse, Wei = Goat, Shen = Monkey, You = Rooster, Xu = Dog, Hai = Pig. Monthly correspondences (solar-term boundaries) — Yin = 1st month (Start of Spring → Awakening of Insects), Mao = 2nd month (Awakening of Insects → Clear and Bright), Chen = 3rd month (Clear and Bright → Start of Summer), Si = 4th month (Start of Summer → Grain in Ear), Wu = 5th month (Grain in Ear → Minor Heat), Wei = 6th month (Minor Heat → Start of Autumn), Shen = 7th month (Start of Autumn → White Dew), You = 8th month (White Dew → Cold Dew), Xu = 9th month (Cold Dew → Start of Winter), Hai = 10th month (Start of Winter → Major Snow), Zi = 11th month (Major Snow → Minor Cold), Chou = 12th month (Minor Cold → Start of Spring). Hour correspondences — Zi hour = 23-1h, Chou hour = 1-3h, Yin hour = 3-5h, Mao hour = 5-7h, Chen hour = 7-9h, Si hour = 9-11h, Wu hour = 11-13h, Wei hour = 13-15h, Shen hour = 15-17h, You hour = 17-19h, Xu hour = 19-21h, Hai hour = 21-23h. Hidden Stems (must memorize) — Zi hides Gui Water, Chou hides Ji-Gui-Xin, Yin hides Jia-Bing-Wu, Mao hides Yi Wood, Chen hides Wu-Yi-Gui, Si hides Bing-Wu-Geng, Wu hides Ding-Ji, Wei hides Ji-Ding-Yi, Shen hides Geng-Ren-Wu, You hides Xin Metal, Xu hides Wu-Xin-Ding, Hai hides Ren-Jia. Memory pattern for hidden stems: the 'Four Cardinal' branches (Zi, Wu, Mao, You) hide only their primary qi (Gui, Ding, Yi, Xin); the 'Four Birth' branches (Yin, Shen, Si, Hai) hide three stems (primary qi + generator + completer); the 'Four Storage' branches (Chen, Xu, Chou, Wei) hide three stems (primary qi + stored item + residual qi). Branch Six Combinations — Zi-Chou combine to Earth, Yin-Hai combine to Wood, Mao-Xu combine to Fire, Chen-You combine to Metal, Si-Shen combine to Water, Wu-Wei combine to Fire (Sun-Moon combination). Branch Three Combinations — Shen-Zi-Chen form Water frame, Hai-Mao-Wei form Wood frame, Yin-Wu-Xu form Fire frame, Si-You-Chou form Metal frame. Branch Three Meetings — Yin-Mao-Chen meet Eastern Wood frame, Si-Wu-Wei meet Southern Fire frame, Shen-You-Xu meet Western Metal frame, Hai-Zi-Chou meet Northern Water frame. Branch Six Clashes — Zi-Wu clash, Chou-Wei clash, Yin-Shen clash, Mao-You clash, Chen-Xu clash, Si-Hai clash. Branch Six Harms (Piercing) — Zi-Wei harm, Chou-Wu harm, Yin-Si harm, Mao-Chen harm, Shen-Hai harm, You-Xu harm. Branch Three Punishments — Ungracious punishment (Zi punishes Mao, Mao punishes Zi), Power-abuse punishment (Yin punishes Si, Si punishes Shen, Shen punishes Yin), Ungrateful punishment (Chou punishes Xu, Xu punishes Wei, Wei punishes Chou). Self-punishment — Chen-Chen self, Wu-Wu self, You-You self, Hai-Hai self.

III. Five Element Generation and Control and the Sixty Jiazi — The Underlying Calculation Rules of Bazi

Five Element generation and control are the 'computational engine' of bazi deduction — every bazi judgment ultimately resolves to this layer of Five Element rules. Five Element Generation — Wood generates Fire (drilling wood makes fire), Fire generates Earth (fire ash becomes soil), Earth generates Metal (earth gestates ore), Metal generates Water (metal condenses water droplets), Water generates Wood (water nourishes wood). Memory method: 'Wood Fire Earth Metal Water' in sequence — adjacent elements generate. Five Element Control — Wood controls Earth (roots break soil), Earth controls Water (dikes block water), Water controls Fire (water extinguishes fire), Fire controls Metal (fire melts metal), Metal controls Wood (axe fells tree). Memory method: skip one to control — Wood skips Fire to control Earth, Fire skips Earth to control Metal, and so on. Quantitative understanding of generation and control — generation is not 'more is always better,' control is not 'always bad.' An element over-generated causes 'mother pampers to death' (e.g., too much Wood smothers Fire — too much Wood actually extinguishes Fire). Over-controlled causes 'child bullied by father' (e.g., Wood too heavily controlled by Metal becomes useless scrap). The ideal state for any Five Element is 'generation and control in balance.' The Sixty Jiazi — the least common multiple of Heavenly Stems (10) and Earthly Branches (12) is 60, forming the Sixty Jiazi cycle — from Jia Zi to Gui Hai, 60 stem-branch pairs total, each an independent analytical unit in bazi. Sixty Jiazi sequence table (must memorize): Jia Zi 1 → Yi Chou 2 → Bing Yin 3 → Ding Mao 4 → Wu Chen 5 → Ji Si 6 → Geng Wu 7 → Xin Wei 8 → Ren Shen 9 → Gui You 10 → Jia Xu 11 → Yi Hai 12 → Bing Zi 13 → Ding Chou 14 → Wu Yin 15 → Ji Mao 16 → Geng Chen 17 → Xin Si 18 → Ren Wu 19 → Gui Wei 20 → Jia Shen 21 → Yi You 22 → Bing Xu 23 → Ding Hai 24 → Wu Zi 25 → Ji Chou 26 → Geng Yin 27 → Xin Mao 28 → Ren Chen 29 → Gui Si 30 → Jia Wu 31 → Yi Wei 32 → Bing Shen 33 → Ding You 34 → Wu Xu 35 → Ji Hai 36 → Geng Zi 37 → Xin Chou 38 → Ren Yin 39 → Gui Mao 40 → Jia Chen 41 → Yi Si 42 → Bing Wu 43 → Ding Wei 44 → Wu Shen 45 → Ji You 46 → Geng Xu 47 → Xin Hai 48 → Ren Zi 49 → Gui Chou 50 → Jia Yin 51 → Yi Mao 52 → Bing Chen 53 → Ding Si 54 → Wu Wu 55 → Ji Wei 56 → Geng Shen 57 → Xin You 58 → Ren Xu 59 → Gui Hai 60. Memory method — divide the Sixty Jiazi into six 'Jia Decads' (Jia Zi decad, Jia Xu decad, Jia Shen decad, Jia Wu decad, Jia Chen decad, Jia Yin decad), each containing ten stem-branch pairs; use the decad head to remember the decad's range. You don't need to memorize every sequence number (though it speeds up Luck Cycle setup enormously). The minimum requirement is: given any stem-branch pair, immediately state its approximate position among the sixty and the pair before and after it.

IV. Five Element Strength-Decline System — Flourishing-Prosperous-Resting-Imprisoned-Dead and the Twelve Life Stages

The strength of the Five Elements across the four seasons is dynamically changing — the same Five Element in different months has enormously different power. The ancients used two systems to describe this seasonal strength variation. First system — Flourishing-Prosperous-Resting-Imprisoned-Dead (benchmarked against the monthly branch). Rule: the current seasonal element is Flourishing (whatever Five Element the month belongs to, that element is strongest this month). The element that generates the seasonal element is Prosperous (second strongest). The element generated by the seasonal element is Resting (declining). The element controlled by the seasonal element is Dead (weakest). The element that controls the seasonal element is Imprisoned (suppressed). Examples — Yin Mao month (Spring, Wood season): Wood Flourishing, Fire Prosperous, Water Resting, Earth Dead, Metal Imprisoned. Si Wu month (Summer, Fire season): Fire Flourishing, Earth Prosperous, Wood Resting, Metal Dead, Water Imprisoned. Shen You month (Autumn, Metal season): Metal Flourishing, Water Prosperous, Earth Resting, Wood Dead, Fire Imprisoned. Hai Zi month (Winter, Water season): Water Flourishing, Wood Prosperous, Metal Resting, Fire Dead, Earth Imprisoned. Chen Xu Chou Wei month (Four-Season Earth month): Earth Flourishing, Metal Prosperous, Fire Resting, Water Dead, Wood Imprisoned. Memory mnemonic: 'Current season Flourishing, I-generate Prosperous, generates-me Resting, I-control Dead, controls-me Imprisoned.' Second system — the Twelve Life Stages (the Twelve Life Cycles). This system is more granular than Flourishing-Prosperous-Resting-Imprisoned-Dead, dividing each stem's state in each branch into twelve phases: Growth (newborn, like an infant) → Bath (bathing, fragile period) → Cap (capping ceremony, rapid growth) → Official (taking office, strength rising) → Peak (zenith, maximum power) → Decline (downhill) → Sickness (problems emerge) → Death (power extinguished) → Tomb (entombed, stored) → Extinction (breath severed) → Embryo (re-conception) → Nurture (gestation and growth). The four most critical nodes among the Twelve Stages — Growth (power starting point), Peak (power zenith), Death (power endpoint), Extinction (weakest point). Arrangement rule for the Twelve Stages — Yang stems go forward (their Growth positions follow branch order), Yin stems go backward (their Growth positions follow reverse branch order). Five Element Growth branch positions — Wood grows at Hai, Fire grows at Yin, Earth and Water grow at Shen, Metal grows at Si. Core practical uses of the Twelve Stages — judging the Day Master's strength grade in a given month (whether the day stem sits at Growth or Extinction in the monthly branch directly determines the Day Master's strength-weakness judgment), judging Ten God strength grades (Useful God at Peak = great fortune, Annoying God at Peak = great trouble), judging the strength cycle of Luck Cycles and Annual Stars (a Luck Cycle branch carrying the Day Master's Growth or Peak = the Day Master's best state in this luck phase).

V. Casting a Bazi Chart and Setting Up Luck Cycles — Must-Memorize Algorithmic Formulas

Casting a chart and setting up Luck Cycles is the operational foundation of bazi study — not knowing how to cast a chart is like not knowing how to write but trying to compose an essay. Four-step formula for casting a chart. Step 1 — Cast the Year Pillar. The Year Pillar uses 'Start of Spring' as the boundary — not the Spring Festival (lunar new year) and not January 1st (solar new year), but rather around February 4th or 5th each year (Start of Spring) as the starting point of the year. Born before Start of Spring = previous year's stem-branch. Born after Start of Spring = current year's stem-branch. The year stem-branch is directly checked from a perpetual calendar — no calculation needed. Step 2 — Cast the Month Pillar. The Month Pillar uses 'solar terms' as boundaries — 1st month (Yin) = Start of Spring → Awakening of Insects, 2nd month (Mao) = Awakening of Insects → Clear and Bright, 3rd month (Chen) = Clear and Bright → Start of Summer, and so on. The month stem uses the 'Five Tiger Push' — the month-stem-from-year-stem formula: 'Jia-Ji years begin with Bing, Yi-Geng years begin with Wu, Bing-Xin must begin with Geng, Ding-Ren begin with Ren, as for Wu-Gui where to start, Jia Yin is the good path.' Expanded: year stem Jia or Ji → 1st month = Bing Yin, year stem Yi or Geng → 1st month = Wu Yin, year stem Bing or Xin → 1st month = Geng Yin, year stem Ding or Ren → 1st month = Ren Yin, year stem Wu or Gui → 1st month = Jia Yin. Once the 1st month is fixed, the 2nd month is the next stem-branch pair in sequence, and so on. Step 3 — Cast the Day Pillar. The Day Pillar must be checked against a perpetual calendar — no formula can accurately calculate the day pillar without a perpetual calendar (existing formulas have unacceptably high error rates). The perpetual calendar is the only reliable method for the day pillar. Step 4 — Cast the Hour Pillar. The hour stem uses the 'Five Rat Push' — the hour-stem-from-day-stem formula: 'Jia-Ji still add Jia, Yi-Geng Bing leads off, Bing-Xin from Wu rises, Ding-Ren Geng Zi resides, as for Wu-Gui where to start, Ren Zi is the true path.' Expanded: day stem Jia or Ji → Zi hour = Jia Zi, day stem Yi or Geng → Zi hour = Bing Zi, day stem Bing or Xin → Zi hour = Wu Zi, day stem Ding or Ren → Zi hour = Geng Zi, day stem Wu or Gui → Zi hour = Ren Zi. Once the Zi hour stem-branch is fixed, the Chou hour is the next pair, and so on. Luck Cycle setup formula — Step 1: Determine direction. Yang year (Jia/Bing/Wu/Geng/Ren) male + Yin year (Yi/Ding/Ji/Xin/Gui) female → forward (count from month pillar forward). Yin year male + Yang year female → backward (count from month pillar backward). Step 2: Calculate starting age. Forward counters: number of days from birth to the next solar term ÷ 3. Backward counters: number of days from birth backward to the previous solar term ÷ 3. The quotient is the starting age; the remainder × 4 months is added. Complete Luck Cycle procedure — first fix the direction, then calculate the starting age, then arrange each Luck Cycle step in Sixty Jiazi order (each step = 10 years), and finally calculate the start and end ages for each step.

Multi-Dimensional Breakdown

Career & Wealth

The solidity of foundational knowledge directly determines the accuracy and speed of practical judgments. Unfamiliarity with Ten Heavenly Stem images — seeing a Jia Wood Day Master without instantly forming the 'pillar of society / leader type' judgment frame, causing every subsequent analysis to lag half a step. Unfamiliarity with branch hidden stems — hesitating among hidden stems when selecting the pattern from the monthly branch, drastically lowering pattern judgment efficiency. Unfamiliarity with the Sixty Jiazi — having to count from the beginning (Jia Zi → Yi Chou → Bing Yin…) when setting up Luck Cycles, incredibly time-consuming. Unfamiliarity with the Twelve Life Stages — judging Day Master strength by feel without rigorous deduction, sharply increasing the probability of choosing the wrong Useful God. The fluency of foundational knowledge = the 'CPU clock speed' of bazi practice — the higher the clock speed, the faster and more accurate the analysis of the same chart.

Love & Relationship

The stem-branch combination and transformation rules of foundational knowledge directly determine judgments about the Spouse Palace and Spouse Star. The day branch (Spouse Palace) participating in a combination frame — the spouse is easily 'combined away' by external forces (e.g., day branch Zi Water combined away by month branch Chou Earth → spouse overly entangled with the chart-owner's family members, affecting the independence of the marriage). The Five Stem Combinations falling on the Spouse Star (Wealth star or Officer star combined) — tendency for the spouse to be 'shared' or diverted. Branch Six Clashes falling on the Spouse Palace — structural instability in the marriage. These judgments all depend on precise memory of foundational knowledge — get one combination-transformation rule wrong and the marriage judgment veers in the wrong direction.

Personality

The images of the Ten Heavenly Stems directly correspond to basic personality types — Jia Wood type (leader, upright), Yi Wood type (adapter, flexible), Bing Fire type (infectious, passionate), Ding Fire type (focused, internally refined), Wu Earth type (accumulator, solid), Ji Earth type (nourisher, inclusive), Geng Metal type (transformer, decisive), Xin Metal type (perfectionist, refined), Ren Water type (connector, grand), Gui Water type (penetrator, subtle). The day stem + month combination refines personality — Jia Wood born in Yin-Mao month = Wood even stronger and more upright but potentially too rigid and brittle; Jia Wood born in Shen-You month = Wood trimmed by Metal into a 'bonsai' personality. These judgments are all built on complete fluency in foundational knowledge — if the Ten Heavenly Stem images aren't memorized cold, personality analysis becomes a heap of vague adjectives.

Health

Correspondences between Five Elements and organs — Wood = liver and gallbladder, Fire = heart and small intestine, Earth = spleen and stomach, Metal = lungs and large intestine, Water = kidneys and bladder. These foundational correspondences are the starting point for bazi health judgments. If the Five Element represented by the day stem is excessively controlled in the chart — the corresponding organ system is the chart-owner's lifelong health vulnerability. Charts with severe Five Element imbalance — the organ system corresponding to the missing Five Element is more prone to problems. If the day stem sits at 'Sickness,' 'Death,' or 'Extinction' in the Twelve Life Stages — the Day Master's innate vitality is weaker, overall constitution is fragile. These health judgments depend completely on accurate correspondence with Five Element foundational knowledge.

Practical Application

Ten Heavenly Stems and Twelve Earthly Branches — Fluent Within Three Days : Spend three days in focused assault on the hard memorization of stems and branches — Day 1: memorize the Ten Heavenly Stems order + Yin-Yang + Five Elements + directions (Jia-Yi Wood East → Bing-Ding Fire South → Wu-Ji Earth Center → Geng-Xin Metal West → Ren-Gui Water North). Day 2: memorize the Twelve Earthly Branches order + Five Elements + zodiac (Zi Rat Water → Chou Ox Earth → Yin Tiger Wood → Mao Rabbit Wood…). Day 3: drill — given any random stem or branch, instantly reflect its Five Element, Yin-Yang, direction, and zodiac. Self-test using a phone memo: write 10 random stem-branch items and answer their attributes with the book closed. Don't proceed further until you reach reflex-level fluency after three days.
Five Stem Combinations and Branch Combinations, Clashes, Punishments, Harms — One-Week Memorization Plan : Days 1-2: memorize the Five Stem Combinations (Jia-Ji Earth / Yi-Geng Metal / Bing-Xin Water / Ding-Ren Wood / Wu-Gui Fire). Use a rhyme: 'Jia-Ji central, Yi-Geng righteous, Bing-Xin authority, Ding-Ren excess, Wu-Gui merciless yet feeling.' Days 3-4: memorize Branch Six Combinations and Six Clashes (Six Combos = Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, Si-Shen, Wu-Wei; Six Clashes = Zi-Wu, Chou-Wei, Yin-Shen, Mao-You, Chen-Xu, Si-Hai). Six Combos and Six Clashes have positional patterns — Six Combos face each other on the branch wheel (Zi and Chou face each other), Six Clashes also face each other but in opposite directions (Zi and Wu clash north-south). Days 5-6: memorize Three Combinations, Three Meetings, Three Punishments, Six Harms. Day 7: concentrated cross-drill — given a branch, list every combination, clash, punishment, and harm relationship it participates in. For example 'Zi' → Six Combo Chou, Six Clash Wu, Three Combo Shen-Chen (Shen-Zi-Chen Water frame), Three Meeting Hai-Chou (Hai-Zi-Chou Water frame), Six Harm Wei, Three Punishment Mao.
Sixty Jiazi — Memorize by Six Jia Decads : Don't try to memorize all 60 at once. Divide into six Jia Decads — Jia Zi decad (Jia Zi → Gui You, 10 items, Kong Wang = Xu Hai), Jia Xu decad (Jia Xu → Gui Wei, 10 items, Kong Wang = Shen You), Jia Shen decad (Jia Shen → Gui Si, 10 items, Kong Wang = Wu Wei), Jia Wu decad (Jia Wu → Gui Mao, 10 items, Kong Wang = Chen Si), Jia Chen decad (Jia Chen → Gui Chou, 10 items, Kong Wang = Yin Mao), Jia Yin decad (Jia Yin → Gui Hai, 10 items, Kong Wang = Zi Chou). Memorize one decad (10 items) per day — six days total. While memorizing, note each decad's Kong Wang — Jia Zi decad Kong Wang Xu-Hai, Jia Xu decad Kong Wang Shen-You… this is the foundation of Kong Wang theory; memorizing the Sixty Jiazi automatically embeds the Kong Wang pairs.
Cast 10 Charts by Hand — Formulas Internalize as Muscle Memory : Find 10 birth dates (family, friends, or historical figures), use a perpetual calendar, and cast each one manually. For each chart, walk through all four steps — ① Five Tiger Push to calculate the month stem, ② check perpetual calendar for the day pillar, ③ Five Rat Push to calculate the hour stem, ④ determine Luck Cycle direction via Yang/Yin year and gender + count solar-term days to calculate starting age. For the first 3 charts, refer to the formulas as needed. For the middle 4 charts, try to rely only on memory. For the last 3 charts, use no reference materials at all. After 10 charts, the 'muscle memory' of chart-casting is established — from then on, seeing any chart triggers the casting process automatically in your mind.

Common Questions

Q: Do I really need to memorize the Sixty Jiazi down to the sequence numbers? Must I see Jia Wu and instantly know it's #31?

You don't strictly need the sequence numbers, but you must reach this level: seeing any stem-branch pair, immediately name the one before it and the one after it. This skill directly determines Luck Cycle setup speed — Luck Cycles start from the month pillar; if the month pillar is Jia Wu, the next forward step is Yi Wei, the previous backward step is Gui Si. If you see Jia Wu and have to count from the beginning — 'Jia Zi, Yi Chou, Bing Yin…' — you're wasting dozens of seconds per chart. Strongly recommended: memorize to the level of 'see a stem-branch, reflexively name its neighbors.' Sequence numbers are a bonus (31 = Jia Wu, 52 = Yi Mao) — nice to have but not a hard gate.

Q: Which system should I actually use — the Twelve Life Stages or Flourishing-Prosperous-Resting-Imprisoned-Dead? Won't the two systems contradict each other?

The two systems do not contradict — they describe strength at different granularities. Flourishing-Prosperous-Resting-Imprisoned-Dead is 'coarse-grained' — only looks at the monthly branch, giving a quick general strength state for each Five Element. The Twelve Life Stages are 'fine-grained' — precisely locate every Heavenly Stem's specific state in every Earthly Branch. In practice, use 'coarse-grained rapid positioning + fine-grained precise correction': first use Flourishing-Prosperous-Resting-Imprisoned-Dead to judge the Day Master's general strength (flourishing or declining) in three seconds, then use the Twelve Life Stages to check the day stem's specific position in the monthly branch. If Flourishing-Prosperous says 'flourishing' but the day stem sits at 'Extinction' in the monthly branch — the flourishing is false; fine-grained correction overrules the coarse-grained judgment. Use both systems together, cross-validating.

Q: Stem combination and transformation — does Jia-Ji really transform to Earth? Under what conditions does true transformation occur?

Combination and transformation are two different things — combination means 'come together'; transformation means 'become something new.' Jia-Ji combination = Jia Wood and Ji Earth will 'combine' (mutually attract) under any conditions, but transformation into Earth requires strict conditions: ① the monthly branch must be Earth in command (Chen, Xu, Chou, Wei months), ② Earth's force in the chart must be sufficiently strong (Earth roots in the branches), ③ the two combining stems must not be separated by other stems or broken by control. Conditions incomplete = combined but not transformed — Jia Wood and Ji Earth attract each other but Jia Wood stays Wood and Ji Earth stays Earth; they're close but not merged into one family. Conditions fully met = combined and transformed to Earth — Jia Wood becomes part of Earth, the chart's Wood nature replaced by Earth nature. In practice, the vast majority of cases are 'combined without transformation' or 'transformed incompletely' — 100% true transformation is extremely rare; most cases show 'transformation tendency' or 'partial transformation.'

Q: When branch combinations, clashes, punishments, and harms all appear together, which takes priority?

Priority order: Three Meetings > Three Combinations > Six Combinations > Six Clashes > Three Punishments > Six Harms. Logic: Three Meetings have the greatest force (three same-direction branches confirming the strongest Five Element hegemony). Three Combinations next (three Growth-Peak-Tomb branches forming a complete Five Element cycle). Six Combinations after that (one-to-one combination, lower force level). Clashes come after combinations — because combinations first 'bind' the branches, clash effects are limited by the combination. If a Six Combination and a Six Clash coexist (e.g., Zi-Chou combination also with Wu clashing Zi), handle as 'combine first, clash after' — Zi is first bound by Chou; Wu's clash force is partially offset by the combination. Three Punishments and Six Harms have the lowest priority — they only manifest significantly with Luck Cycle and Annual Star cooperation; punishments and harms in the natal chart are more latent risks. Practical mnemonic: 'Meetings and combinations can dissolve clashes; clashes can also break combinations' — Meeting/Combination force can neutralize clash destructiveness, and conversely, a sufficiently strong clash can dismantle a combination structure.

Q: When casting a chart, is the year pillar based on Spring Festival or Start of Spring? Online sources disagree.

One hundred percent Start of Spring — this is an iron rule of bazi study. Start of Spring is not a fixed solar date; it typically falls around February 4th or 5th — you must check the perpetual calendar for the specific year. Someone born before Start of Spring, even if after the lunar New Year's Day (Spring Festival), still uses the previous year's stem-branch for the year pillar. For example, in 2024, Start of Spring is February 4th; someone born on February 3rd (after Spring Festival but before Start of Spring) still has year pillar Gui Mao (2023), not Jia Chen. The lunar calendar is the state administrative calendar; the solar terms are the celestial movement calendar — bazi uses the celestial movement calendar (solar terms determine year and month), so both the year pillar and the month pillar use solar-term boundaries. This is an extremely common beginner mistake — recklessly assigning the next year for births after Spring Festival — and must be corrected.
