Every term, three readings — side-by-side.

Emperor Star (紫微 / Zǐ Wēi)

Central authority, the seat of decision-making in the 12-room map.

Sun in Leo with a strong Saturn, or a loaded 10th house

The dignity of Leo without its theatricality, plus the structural seriousness Saturn brings to a chart; the 10th-house overlap covers public role and authority.

Patterns described in popular literature as INTJ or ENTJ

The common thread is strategic distance: long-range planning combined with reluctance to micromanage.

Mechanism Star (天機 / Tiān Jī)

The advisor and analytical engine of the 14-star set; reads patterns and runs scenarios.

Mercury-dominant chart, especially Mercury in air signs

Gemini, Aquarius, or Libra Mercury, plus 3rd-house emphasis, produces the closest behavioural overlap: quick speech, comparative thinking, fondness for variety.

Patterns described in popular literature as INTP, ENTP, or INTJ

Western pop psychology often pathologizes the restlessness (the ADHD framing). ZWDS treats the same trait as the working condition of the instrument.

Sun Star (太陽 / Tài Yáng)

Visible role, father archetype, outward energy. Narrower than Western 'sun sign'.

Sun in Leo, or a strong 10th-house Sun

The public-role overlap is direct. The 'identity proxy' reading of the Western Sun does not carry over — ZWDS distributes identity across the full 14-star set, not just this one position.

Patterns described in popular literature as ENFJ or ENTJ

The 'presence radiates' types — high-warmth extroverts who hold rooms. The chart does not collapse a person to one type; it just notes which life areas the radiating energy lands in.

General Star (武曲 / Wǔ Qū)

Operator and executor. The hard edge is the instrument, not the moral verdict.

Mars in Capricorn, or a strong 8th-house Mars-Saturn signature

Practical Mars produces the same operator profile — getting things done at the level of contracts, resources, and shared finance.

Patterns described in popular literature as ESTJ or ESTP

High agency plus task focus. Both types end up running operations in popular profile writeups.

Harmony Star (天同 / Tiān Tóng)

Ease and comfort as both gift and limit. The 'blessing star' that the chart treats with two-handed honesty.

Venus-Jupiter ease, with Cancer or Pisces emphasis; a 2nd-house comfort signature

The same gentleness profile. Western astrology tends to read this configuration as 'high abundance' rather than as the trade-off ZWDS frames.

Patterns described in popular literature as ISFP, INFP, ENFP, or ESFJ

Warm, low-conflict types. ZWDS names the cost of low-conflict patterns alongside the gift; pop type writeups generally do not.

Officer Star (廉貞 / Lián Zhēn)

The principled-and-sensual paradox. The only main star whose classical reputation runs on opposed circuits.

Scorpio Sun with a strong Mars or Pluto signature; a loaded 8th house

Intense, psychologically deep, conscience-driven. The closest Western archetype for the same internal tension.

Patterns described in popular literature as INTJ, INFJ, or ENTJ

The judicial-intuitive cluster — strong internal code combined with the kind of perception that reads people's actual motives quickly.

Treasury Star (天府 / Tiān Fǔ)

The imperial storehouse. Stewardship and conservation as the structural counterpart to Emperor Star's authority.

Taurus Sun with a strong Saturn, or a loaded 2nd or 4th house

Taurus carries the stewardship temperament; Saturn adds structural conservatism; 2nd-house (resources) and 4th-house (home, inheritance) signatures cover the Property Palace overlap.

Patterns described in popular literature as ISTJ or ESTJ

The custodian profile — duty-bound, detail-attentive, institutional. Both types end up running the back office in popular type writeups.

Moon Star (太陰 / Tài Yīn)

The receptive luminary. Inward giving as the structural counterpart to Sun Star's outward radiation.

Moon in Cancer or Pisces, or a loaded 4th or 12th house

The same interior orientation — emotional depth, receptivity, the private rather than performative side of a chart.

Patterns described in popular literature as INFJ, INFP, or ISFJ

Introverted-feeling cluster — depth-first processing, quiet generosity, strong but rarely advertised inner life.

Wolf Star (貪狼 / Tān Láng)

Appetite as structural orientation. One of the two principal peach-blossom stars; the chart's most direct map of multiplicity of interest and social magnetism.

Sagittarius Sun, or a strong Jupiter; a loaded 5th or 11th house

Jupiter expansiveness produces the same multi-vector appetite; the 5th house covers pleasure and creative pursuit, the 11th house covers wide social networks.

Patterns described in popular literature as ENTP, ENFP, or ESTP

Extraverted-perceiving cluster — high social bandwidth, broad interest range, and a working preference for keeping multiple options open.

Gate Star (巨門 / Jù Mén)

Language as the chart's instrument. One of two 'dark luminaries' — operating by what it questions, refuses, or sharpens, rather than by outward radiation.

Mercury with hard aspects to Saturn or Pluto; a Scorpio-Mercury or Gemini-Mars signature

Sharpened communication — the analytical voice with bite. Western astrology tends to read this as 'critical thinker' rather than as the relational-risk profile ZWDS names alongside the precision.

Patterns described in popular literature as ENTP, INTP, or INTJ

Debater-and-analyst cluster — comfort with disagreement, preference for verbal precision, and willingness to interrogate assumptions other types treat as settled.

Minister Star (天相 / Tiān Xiàng)

The seal-bearer. Value through service to a principal worth serving; authority becomes effective through this role, not despite it.

Libra Sun with a well-aspected Saturn, or a strong 10th-house Saturn signature

Libra diplomacy combined with Saturn's institutional gravity — the same chief-of-staff profile, dignified and competent within established structures.

Patterns described in popular literature as ISFJ, ESFJ, or ISTJ

The duty-and-service cluster — high reliability, strong sense of role obligation, and the kind of working competence that organisations come to depend on.

Pillar Star (天梁 / Tiān Liáng)

The shade and the roof-beam. Eldership as a structural function — protection extended downward, wisdom carried through stubbornness.

Sagittarius or Capricorn Sun with a strong Jupiter or Saturn; a loaded 9th house

Sagittarian philosophical breadth combined with Saturn's mature gravity; the 9th-house overlap covers teaching, religion, and senior advisory roles.

Patterns described in popular literature as INFJ, INTJ, or ISTJ

The sage-and-counsellor cluster — long-range thinking, comfort with advisory roles, and the quiet stubbornness the chart explicitly names.

Slayer Star (七殺 / Qī Shā)

The frontline operator. Solitary courage as a structural orientation; the instrument is built for friction, not for low-stakes environments.

Mars in Scorpio or Aries, with a strong Pluto signature; a loaded 8th house

The high-intensity Mars profile — direct, surgical, unafraid of confrontation; 8th-house overlap covers surgery, risk, and the kind of intensity Western astrology associates with Scorpio-Pluto.

Patterns described in popular literature as ISTP or ESTP

The tactical operator cluster — comfort with action under pressure, low tolerance for unnecessary process, and the kind of working profile that thrives in real frontline roles.

Breaker Star (破軍 / Pò Jūn)

Destruction-and-renewal as a structural function. The energy is expenditure; the value is the ground the expenditure clears.

Uranus or Pluto in hard aspect to the Sun; a loaded 8th house with reformist Mars

Uranian disruption and Plutonian death-rebirth — the same cyclic pattern Western astrology names for chart configurations that produce reinventors and pioneers.

Patterns described in popular literature as ENTP, ENFP, or INTP

The iconoclast-and-entrepreneur cluster — high tolerance for upheaval, low patience with incremental improvement, and a working preference for new ground over inherited structures.

Left Assistant Star (左輔 / Zuǒ Fǔ)

Reliable support; makes the adjacent main star's authority functional rather than decorative.

North Node conjunct a personal planet, or a well-aspected 6th house

The overlap is the idea of supportive destiny alignment — something that makes existing strengths more accessible. The 6th-house parallel captures the service orientation without the mythology.

Patterns described in popular literature as ISFJ or ISTJ

The loyalty-first, execution-oriented style maps loosely to Left Assistant's role. The parallel is functional, not structural — 16-type measures cognitive preference, not relational position.

Right Aide Star (右弼 / Yòu Bì)

Social connectivity; the relationship-building half of the classical assistant pair.

Venus in the 7th or 11th house, or Jupiter trine the Ascendant

The overlap is social grace that operates structurally — not mere charm, but the capacity to build durable alliances.

Patterns described in popular literature as ENFJ or ESFJ

The social-connector orientation maps loosely. Both are archetypes of people who maintain group cohesion as a core function.

Scholar Star (文昌 / Wén Chāng)

Structured learning, documented knowledge, credential-based recognition.

Mercury in Virgo or Capricorn, or a strong 9th house with Saturn aspects

The parallel is disciplined intellectualism — not creative inspiration, but the kind of intelligence that organizes, documents, and passes external evaluation.

Patterns described in popular literature as INTJ or INTP

The systematic-intellectual overlap is strong. The parallel is the preference for structured knowledge over experiential learning.

Arts Star (文曲 / Wén Qǔ)

Expressive intelligence, performance, aesthetic sensibility.

Mercury in Gemini or Libra, or Venus conjunct the Midheaven

The parallel is communicative grace — intelligence expressed through style, timing, and audience awareness rather than documentation.

Patterns described in popular literature as ENFP or INFP

The expressive-idealist overlap maps loosely. Both describe people for whom the medium of expression matters as much as the content.

Day Noble Star (天魁 / Tiān Kuí)

Overt institutional support; the patron who recognizes and promotes you publicly.

Jupiter conjunct the Midheaven, or a strong 10th-house benefic

The parallel is visible career luck — advancement that comes through institutional channels and recognized authority.

Not directly mapped

Noble stars describe relational dynamics (who helps you and how), not cognitive preference. The 16-type system does not have an equivalent axis.

Night Noble Star (天鉞 / Tiān Yuè)

Informal support; the benefactor who operates through networks rather than institutions.

Neptune trine Jupiter, or a strong 12th-house benefic

The 12th-house parallel captures the 'hidden support' quality — benefits that arrive from sources not immediately visible.

Not directly mapped

Like Day Noble, Night Noble describes relational dynamics rather than cognitive preference. The 16-type system does not model this axis.

Fire Star (火星 / Huǒ Xīng)

Explosive acceleration; the initial surge of energy that can launch or destabilize.

Mars conjunct the Ascendant or in Aries, or Uranus hard aspects to personal planets

The impulsive-action overlap is strong. Mars-Uranus aspects specifically capture the sudden, not-fully-deliberated quality.

Patterns described in popular literature as ESTP or ENTP

The action-first, deliberate-later orientation maps loosely. The parallel is behavioral tempo, not cognitive structure.

Bell Star (鈴星 / Líng Xīng)

Deferred intensity; pressure that accumulates silently before a concentrated release.

Pluto conjunct a personal planet, or Saturn-Mars aspects with slow-transit triggers

The Pluto parallel captures the buried-pressure-then-transformation quality. Saturn-Mars adds the idea of delayed action finally releasing.

Not directly mapped

Bell Star describes a temporal pattern of behavior (delayed release), not a cognitive preference. No clean 16-type parallel exists.

Ram Star (擎羊 / Qíng Yáng)

Direct confrontation; visible obstacles that demand frontal engagement.

Mars square Saturn, or Mars in the 1st house with hard aspects

The forced-confrontation quality maps well. Mars-Saturn specifically captures the idea of action meeting resistance head-on.

Not directly mapped

Ram Star describes an environmental friction pattern, not a cognitive preference. There is no clean 16-type equivalent for 'obstacles concentrate here.'

Spinning Star (陀羅 / Tuó Luó)

Cyclical friction; the recurring pattern that demands conscious effort to break.

Saturn square the Moon, or South Node conjunctions with personal planets

The repetition-compulsion quality maps well. The South Node parallel captures the idea of patterns carried forward that feel automatic.

Not directly mapped

Spinning Star describes a behavioral-loop pattern, not a cognitive preference. The 16-type system does not model recurring friction dynamics.

Void Star (地空 / Dì Kōng)

Conceptual emptying; reduces the effectiveness of conventional approaches and opens space for original ones.

Neptune square the Midheaven, or a loaded 12th house with no benefic relief

The dissolution-of-material-structure parallel is strong. Neptune specifically captures the quality of conventional boundaries becoming porous.

Patterns described in popular literature as INTP or INFP

The detachment-from-convention parallel maps loosely. Both describe orientations where internal frameworks matter more than external validation.

Robbery Star (地劫 / Dì Jié)

Abrupt material depletion; concentrated risk of sudden loss that forces rebuilding.

Pluto in the 2nd or 8th house, or Uranus opposed to Venus

The sudden-financial-disruption quality maps well. Pluto-in-2nd captures the wealth-destruction-and-regeneration cycle specifically.

Not directly mapped

Robbery Star describes an event-risk pattern, not a cognitive preference. The 16-type system does not model material-loss dynamics.

Life Palace (命 / mìng)

Anchor cell of the chart; default self at rest; sets where every other palace lands.

Ascendant + 1st house

The Ascendant captures how you arrive in a room; the 1st house carries the rest of the surface identity. Both function as 'default presentation,' which overlaps with the Life Palace's domain — though Zi Wei treats this as one room rather than two layers.

Dominant cognitive function

The function you default to under no external pressure — what you do when nobody is asking anything specific of you. This is the closest 16-type structure to 'who you are at the core' without recruiting your stress response.

Siblings Palace (兄弟 / xiōng dì)

The lateral inner circle — blood siblings plus the two or three peers you treat as siblings.

3rd house, partial

The 3rd house covers siblings and immediate environment, with overflow into communication and short journeys. Zi Wei carves siblings out as its own room and assigns the rest of the 3rd house's territory to other palaces, so the overlap is real but partial.

Inner-circle attachment style

16-type does not address relationships directly, but the cognitive function stack predicts how a person organizes their inner ring — whether they default to a few deep bonds or a wider lattice. The palace describes the result, not the mechanism.

Spouse Palace (夫妻 / fū qī)

Long-term partnership pattern, including marriage, cohabitation, and committed long-term dating equally.

7th house and Venus by sign

The 7th house carries committed partnership and the projected ideal partner; Venus by sign adds the affection style. The Western framework treats these as separate signals; Zi Wei collapses them into one room and reads them through the chart's overall axis.

Inferior-function pairing patterns

Popular 16-type literature observes that long-term partnerships often gravitate toward types that complement the inferior cognitive function. This is folk pattern more than rigorous prediction, but it overlaps loosely with what Zi Wei encodes as 'the partner across the table.'

Children Palace (子女 / zǐ nǚ)

Downstream generativity — biological children, creative output, mentees, durable projects.

5th house, partial

The 5th house in Western astrology covers children, creativity, and romantic play. Zi Wei keeps the children + creativity piece in this room and routes the romance piece to the Spouse Palace, so the overlap is real but the boundaries differ.

Generative-function output pattern

Popular 16-type literature does not assign a single function to 'children,' but the type's preferred output mode — exploratory and idea-driven for some, concrete and protective for others — overlaps with what the Children Palace encodes as 'the shape of what you generate.'

Wealth Palace (財帛 / cái bó)

Money flow signature — income tempo, spending pattern, temperament around money in motion. Distinct from static net worth, which routes to Property.

2nd house

The 2nd house covers possessions, values, and income source. The overlap with Wealth Palace is direct, but Western astrology blends the 'values' (what you treat as valuable) and the 'income' (how money comes in) into one house, while Zi Wei isolates the flow layer here and routes deeper values to Fortune.

Relationship-to-stability function pattern

16-type literature does not directly map a function to money, but the type's tolerance for variable income, comfort with risk, and preferred decision tempo all bear on the shape of the money-flow signature this palace encodes.

Health Palace (疾厄 / jí è)

Somatic stress signature — where physical load lands under sustained pressure and which systems run a chronic-pattern risk.

6th house, partial

The 6th house in Western astrology covers health, daily routine, and work-as-service. The 'health' piece overlaps directly with the Health Palace, but the 6th house also handles the daily-grind and service-orientation themes, which Zi Wei routes to the Career and Friends palaces instead.

Inferior function / stress reaction pattern

Popular 16-type literature describes each type's 'inferior function' — the cognitive mode that surfaces under pressure and tends to drive the type's least healthy behaviors. This loosely overlaps with the Health Palace's encoding of 'how stress expresses itself in this person,' though one is psychological and the other adds a somatic layer.

Travel Palace (遷移 / qiān yí)

Identity-in-motion — who you become when displaced from your familiar frame. Distinct from trips or tourism in any literal sense.

9th house

The 9th house in Western astrology covers long journeys, foreign cultures, higher education, and worldview expansion through displacement. The overlap with the Travel Palace is direct, with the 9th house carrying a slightly broader 'expansion of horizons' meaning that Zi Wei tends to route to multiple palaces rather than concentrate in one.

Type-in-novel-environment shift pattern

16-type literature does not isolate a single 'displacement' function, but observes that each type's auxiliary and tertiary functions surface more visibly under novel environmental pressure. This loosely overlaps with what the Travel Palace encodes — which sides of you become legible when the familiar context drops away.

Friends Palace (交友 / jiāo yǒu) — not Servants Palace

Wider social ring, peer lattice, professional and casual network. Not the inner circle (that lives in Siblings) and not romantic partnership (that lives in Spouse).

11th house

The 11th house covers friends, groups, networks, and collective associations. The overlap with the Friends Palace is direct and unusually clean — both systems carve out 'the wider social ring' as a distinct room.

Extraverted-vs-introverted breadth preference

16-type literature observes that extraverted types tend to build wider, shallower social lattices while introverted types tend to invest in narrower, deeper bonds. The Friends ↔ Siblings axis in Zi Wei is a chart-level version of the same gradient, with the chart describing where any individual lands rather than a categorical preference.

Career Palace (官祿 / guān lù)

Work-identity and trajectory shape — not a forecast of jobs, but the pattern underneath the sequence of jobs.

10th house and Midheaven

The 10th house carries career, public role, and life direction; the Midheaven specifically marks public visibility and vocation. The overlap with the Career Palace is direct. Western astrology tends to read the 10th house through public reception more than internal work-identity, while Zi Wei collapses both into one room.

Dominant function as career signal

16-type literature does not assign careers to types — that produces bad fits — but observes that each type's dominant cognitive function tends to be visible in their professional preferences over a long career arc. The Career Palace encodes a similar 'long-arc trajectory shape' rather than a job-title prediction.

Property Palace (田宅 / tián zhái)

Upstream container — home base, real estate, family of origin, the inherited / built shape that holds you. Distinct from downstream output (Children).

4th house

The 4th house covers home, family of origin, foundations, and the private base of the chart. The overlap with the Property Palace is direct and unusually clean — both systems treat 'where you came from and where you root' as a single room.

Rooting / belonging function

16-type literature does not assign a single function to 'home,' but the type's relationship to tradition, continuity, and inherited structure tends to be visible across long arcs. The Property Palace encodes this at the chart level rather than the cognitive-function level.

Fortune Palace (福德 / fú dé) — not Happiness Palace

Inner state register, baseline mood, contemplative life. Carries both 'blessing' (inherited well-being) and 'virtue' (accumulated inner depth) — broader than hedonic happiness.

12th house, partial

The 12th house in Western astrology covers the hidden self, spirituality, and the inner sanctuary — overlapping with the inner-state half of the Fortune Palace. The 12th house also carries undoing and self-sabotage themes that Zi Wei routes elsewhere, so the overlap is real but partial.

Introverted-perceiving / inner-state tracking

16-type literature describes how introverted perceiving functions (Si and Ni in MBTI terms) shape a person's relationship to their own inner life — what feels familiar, what feels meaningful, what they return to in solitude. This loosely overlaps with what the Fortune Palace encodes.

Parents Palace (父母 / fù mǔ)

Formative authority pattern — parents first, then the whole class of authority figures that succeed them in adult life. Distinct from the somatic imprint (Health) that pairs with it.

Sun (paternal) + Moon (maternal) + Saturn (formative authority)

Western astrology splits the parental pattern across multiple signals: Sun for the father, Moon for the mother, Saturn for formative authority and structure. The 10th house also carries parental themes. Zi Wei collapses all of these into one room and reads them as a single authority-figure signature.

Response-to-authority pattern

16-type literature observes that each type's relationship to hierarchy, rules, and senior figures tends to be stable across life — extraverted thinkers handle authority differently from introverted feelers, and so on. The Parents Palace encodes a chart-level version of the same pattern, tracing it back to its formative source rather than treating it as a static type trait.

Flow Activation (化祿 / huà lù)

Opportunity-flow signal attached to a specific star by year stem; ease arrives in the life area where the carrier sits.

Jupiter benefic in a relevant house

Jupiter brings expansion and ease, and a benefic placement channels that ease through a specific life area. Flow Activation captures a similar 'this area is favored' register, though attached to a fixed life-long star rather than to a transiting planet.

Auxiliary function operating without effort

The auxiliary cognitive function — the one supporting the dominant — at a maturity level where it operates without conscious recruitment. Flow describes the equivalent: a register that runs well without being actively pushed.

Drive Activation (化權 / huà quán)

Agency signal attached to a specific star by year stem; the chart's urge-to-lead register, independent of formal title.

Mars-Saturn combination

Mars supplies the initiating drive; Saturn supplies the structure that converts drive into authority. Drive Activation reads similarly — initiative that organizes itself into a stable shape, without requiring a formal title to operate.

Extroverted thinking (Te) or extroverted intuition (Ne) as primary driver

Both functions push outward into the environment to shape it rather than receive from it. Drive Activation describes a comparable register: the urge to act on the world rather than wait for the world to act.

Recognition Activation (化科 / huà kē)

Reputation signal attached to a specific star by year stem; the chart's being-seen register, with a built-in smooth-recovery quality.

Jupiter in the 10th house or strong Midheaven aspect

The 10th house and the Midheaven govern public reputation in Western astrology. A Jupiter benefic there reads as recognized standing in the public sphere. Recognition Activation describes a similar register, attached to a specific star rather than to a single house.

Tertiary function reaching observable competence

The tertiary function, when developed, becomes a register that others recognize even when the person does not consciously identify with it. Recognition Activation captures something similar — being legibly competent in a register one might not actively foreground.

Friction Activation (化忌 / huà jì)

Chronic-friction signal attached to a specific star by year stem; the chart's where-attention-must-go register. Not deterministic.

Saturn return or hard Saturn aspect

Saturn aspects describe the structural difficulty in a chart — the area where life will require sustained attention. Friction Activation captures a similar register, though attached to a fixed life-long star rather than to a transit cycle. Neither system reads Saturn or Friction as a sentence; both describe the work, not the verdict.

Inferior function or stress-state pattern

The inferior function is the cognitive register where the person is least at home and most likely to produce repeated, recognizable difficulties. Friction Activation describes something similar: the life area where the chart's owner should expect recurring patterns that require attention rather than expecting them to resolve on their own.

Triangle and Axis (三方四正 / sān fāng sì zhèng)

Fixed four-cell cluster: anchor palace + its trine pair + opposite cell. Mandatory reading unit for any serious palace interpretation.

Trine + opposition aspect framework

Western astrology recognizes trine (120°) and opposition (180°) as the two strongest aspects. Triangle and Axis combines them into a single mandatory cluster, with the additional rule that the cluster is fixed by chart geometry rather than chosen case-by-case.

Function pairs + opposing function

The 16-type model pairs cognitive functions into dynamic units: a dominant function pulls in supporting tertiary and sits opposite an inferior. Triangle and Axis describes a comparable structural unit, though geometrically fixed across four cells rather than four functions.

Slayer-Breaker-Wolf Triad (殺破狼 / shā pò láng)

Fixed star triad in mutual trine; structural disruption-and-renewal signature. The triad's home cells determine which life area carries the restart pattern.

Uranus-Pluto major aspect

Uranus and Pluto in major aspect describes the natal signature of someone whose life moves through structural upheaval and transformation. The Slayer-Breaker-Wolf triad reads similarly, though attached to specific stars in specific palaces rather than to two planets in flexible aspect.

Configurations that thrive on disruption (e.g. ENTJ / ENTP / ESTP profiles)

Several 16-type configurations correlate with comfort in disruption and restart cycles — types that thrive in change rather than stability. The Slayer-Breaker-Wolf triad describes a comparable temperament, arrived at through a different structural framework.

Decade Cycle (大限 / dà xiàn)

Ten-year palace rotation overlaying the natal chart. Each decade is hosted by a specific palace; the stars in that palace set the decade's dominant signal.

Annual profections (scaled to decades)

Western profections rotate one house per year; the Decade Cycle rotates one palace per ten years, making it a slower and broader overlay. Both systems share the idea that a natal house 'activates' during its assigned period.

Function development across life stages

The 16-type model proposes that cognitive functions develop in a rough sequence across decades — dominant function solidifying in early adulthood, auxiliary and tertiary emerging later. The Decade Cycle encodes a comparable claim: different life areas become salient in different decades, following a fixed rotation rather than a developmental progression.

Annual Cycle (小限 / xiǎo xiàn)

Year-by-year palace rotation cycling through all twelve palaces. Sits inside the Decade Cycle as a finer temporal layer.

Annual profections

Western annual profections rotate one house per year, matching the Annual Cycle's one-palace-per-year rhythm almost exactly. Both systems use the activated house to frame the year's themes, though the starting house and rotation rules differ.

Situational function activation

The 16-type model does not have a formal annual rotation, but practitioners note that life circumstances can foreground different cognitive functions year by year — a year of caregiving may emphasize Feeling functions, a year of strategic planning may emphasize Thinking. The Annual Cycle encodes a comparable pattern structurally rather than situationally.

Year Stream (流年 / liú nián)

Annual star rearrangement overlaying the natal chart. Calculated from the calendar year's Earthly Branch; universal arrangement, individual interpretation.

Solar return / annual transits

Western astrology reads annual transits (where planets are now relative to the natal chart) and the solar return chart (a snapshot of the sky at the exact birthday). The Year Stream captures a comparable annual overlay, but uses a discrete twelve-year cycle rather than continuous planetary motion.

No direct analog

The 16-type system does not model annual shifts in cognitive function. The closest conceptual parallel is situational type expression — the observation that different environments or life phases pull different functions forward — but this is informal rather than structurally encoded.

Month Stream (流月 / liú yuè)

Monthly star rearrangement within each year. The finest commonly used temporal layer, producing 12–13 unique overlays per year based on lunar months.

Monthly transits / lunar return

Western astrology reads monthly transits — particularly the Moon's movement through the twelve houses over roughly 28 days, and monthly ingresses of faster planets. The Month Stream captures a comparable monthly overlay, though keyed to discrete lunar months rather than continuous planetary motion.

No direct analog

The 16-type system does not model shifts at monthly resolution. At this granularity, situational factors (project type, team composition, stress level) dominate cognitive function expression more than any structural model can encode.
