Birth Time Verification

Preferred time: Yin hour (4:00). The Day Master is Wu Earth with a strong root in the Horse hour. In the Yin hour, Jia appears as the Seven Killings star, which indicates strategic cunning and a talent for military tactics, fitting Li Shimin’s youth when he joined the army, seized the throne at Xuanwu Gate, and led campaigns across the realm. The Yin hour contains hidden Bing and Wu that strengthen Fire and Earth, giving both drive and the capacity to bear leadership responsibilities, reflecting a dual temperament of martial prowess and governance. The lunar month branch Chou is the Direct Official, representing governance achievements and adherence to ritual. The Yin hour can fuse the Seven Killings’ sharp edge with the Direct Official’s order to achieve dominance. Compared with other hours, Mao hour tends toward civil officials and more focus on study; Wealth energy favors diplomacy and strategy, and Wu hour’s peer-based self-confidence can obscure the combination of military decisiveness and governing wisdom. Therefore Yin hour is preferred.

Core Analysis

Li Shimin's chart centers on a strong 戊土日主 duplicated in year and day (both 戊午), producing a powerful 比肩/劫财 presence. This self-strength indicates robust self-will, personal initiative and cohort support—qualities that map to his early military leadership and capacity to act decisively in coalition or confrontation.

The hour pillar 甲寅 brings a pronounced 七杀 factor into the chart. As 七杀, 甲木 operates as a catalytic, aggressive force against 戊土, manifesting as military daring, strategic offense and an ability to subdue rivals—consistent with Li Shimin's battlefield achievements and the decisive move in 626 (玄武门之变).

Overall 格局 shows a dominant self-element supported and pressured by auxiliary forces: abundant 比肩/劫财 supplies willpower and peer alliance, while 七杀 supplies command and tactical aggression. The chart's 五行 fire component (午) fuels initiative and visibility; the presence of 丑、寅 and the 大运 sequence (notably 丁卯 and 戊辰 early on) explain his rising power in youth and consolidation during the Zhenguan reign.

Traits

1

Leadership

High leadership capacity: the duplicated 戊土 (year and day) creates powerful 比肩/劫财, indicating strong self-reliance and the ability to rally close allies—explains decisive rulership and command.

2

Military Strategy

Exceptional military talent: the 甲寅 hour introduces 七杀, a martial and aggressive ten-god, which combined with robust 比肩 drives battlefield daring and tactical initiative.

3

Statecraft & Governance

Strong governance aptitude: supportive 午火 gives public influence and charisma, while balanced earthly energy enables policy implementation; reflected in the effective 贞观之治 era.

4

Interpersonal Flexibility

Moderate flexibility: dominant 比肩/劫财 favors self-assertion and peer alliance over compromise, creating occasional rigidity in court politics and difficulty smoothing conflicts.

Yanmen Strategy: First Glimpse of Brilliance

At sixteen, Li Shimin volunteered for military service and joined the relief effort to rescue Emperor Yang of Sui, who was besieged by the Turks at Yanmen Pass. He proposed a feint to mislead the enemy, used strategic deception, and successfully frightened away the Turkic army, marking the first display of his exceptional strategy and courage in his military career.

Analysis
This year’s annual stem is Yi Hai; the heavenly stem Yi wood is Zheng Guan (Proper Official), and the earthly branch Hai water is Pian Cai (Partial Wealth)—the Wood and Water elements favored by the chart. The annual flow and the Da Yun are semi-conjoined with Wood, further strengthening the 官杀 (official-power) energy. Official power represents career, responsibility, and boldness; for someone whose strength is robust and who likes to restrain, this is an excellent opportunity to turn abundant energy into action and achievement. At the same time, the Hai-water in the annual cycle interacting with the month and hour pillars forms a Three-Water gathering, with Water as wealth star, signaling a convergence of opportunities and resources. The Da Yun’s heavenly stem 丁 Fire as Zheng Yin (proper support) and the hour pillar’s Ren Water as Pian Cai (secondary wealth) harmonize, forming a Wealth-to-Seal synergy, meaning he can combine wisdom (Seal) with opportunities (Wealth) to translate into actual strategy and action. Yanmen’s stratagem epitomizes this dynamic of official power restraining the self, with intellect and cunning on display.

Light Cavalry Breaks the Line, First Signs of Brilliance

Wei Dao'er led the army to besiege Taiyuan, trapping Li Yuan in a tight encirclement. Li Shimin personally led a chosen cavalry to pierce the enemy lines, using precise archery to rout the foe and rescue his father, marking his first display of outstanding military discernment and command.

Analysis
This year Li Shimin is 18, in the 丁卯 Zhengyin big luck cycle, with the annual Bingzi. The chart is a strong Yang Shen drives Sha configuration, favoring the use of Wood (Guan Sha) to manage his over-strong energy. The year's heavenly stem Bing Fire as regulating star brings action and decisiveness, like winter sun, granting him courage to face danger and strike. The year's earthly branch Zi Water together with the year and day pillars Wu Fire form a Zi-Wu double clash, a year of clashes with Tai Sui, signaling intense changes and conflicts appropriate for battlefield life and death. At the same time, Zi Water is wealth star; wealth can generate official power, stimulating the energy of the hour pillar Jia Yin Seven Kill. The Seven Kill energy represents boldness, decisiveness, and military talent; under this year's impulso, the Yang Shen drives Sha pattern's power fully manifests, turning his overly旺 earth energy into charging and defeating enemies, thus earning fame and saving his father.

Under Chang’an, Displaying Prowess; First Enfeoffed as Duke, Governing Jing

Li Shimin followed his father and brothers to invade Chang’an, supporting Prince of Dai Yang You to become emperor; for meritorious service he was appointed the Governor of Jingzhao, conferred as Duke of Qin, officially entering the center of power and beginning to wield military and political authority.

Analysis
This year Li Shimin is in丁卯 Zhengyin great fortune; the flow year is 丁丑. The chart itself is a strong Yang Shen drives Sha pattern, favoring Wood (Guan Sha) to govern his overly旺 energy. The year's heavenly stem 丁 Fire as Zheng Yin appears; though it is an inauspicious star in this chart, when paired with the hour pillar Ren Water, it converts the inauspicious Seal star into a favorable use, signaling support from noble people and official recognition. More importantly, the year's earthly branch Chou and the hour pillar Zi form a 'Hour–Heavenly Ground double harmony', a strong signal of ample assistance, favorable alliances, and career flight. The Chou Earth hides Gui Shui (proper wealth) and Xin Jin (hurt官), meaning that through military strategy (伤官) he can gain real profits and territory (正财). At the same time, auspicious stars such as Tian Yi Gui Ren, Taiji Gui Ren, and Gu Yin arrive, pushing interpersonal relations and official recognition to a peak, perfectly validating the feats of capturing the capital, being enfeoffed as Duke, and governing the Jing region.

Jinyang Strategy: The Dragon's Rise Begins

Li Shimin, Pei Ji, Liu Wenjing and others plotted in secret, successfully persuaded his father Li Yuan to raise troops at Jinyang to resist the Sui, becoming the central driver of the Tang Dynasty’s founding.

Analysis
That year’s Dingchou annual interacts with the birth-hour pillar Jiayin to form a strong 'Heaven and Earth double harmony,' signaling abundant support and smooth sailing both at home and abroad, favorable for forging alliances and launching a career. The year's Ding fire Direct Resource aligns with the Fortune’s Ding fire, and with the hour pillar's Ren Water (the original hour pillar Jiayin contains hidden fire generating Earth; Ren Water here is a symbolic catalyst) triggering noble support and official prestige. The simultaneous appearance of Heavenly Nobleman and Imperial Seal Nobleman marks peak interpersonal and official recognition, a moment when a rallying call attracts followers. Although the chart’s Earth旺 is unfavorable, the fortune's Mao Wood (Direct Official) in the great fortune and the annual Yin Wood (Seven Killings) being triggered together strongly energize the Wood (official and killing energy), greatly boosting decisiveness, responsibility, and pioneering drive, perfectly fitting the leadership pattern of 'Yang blade riding the killing energy.' This move to persuade his father to raise troops is a key step in channeling the overabundant self-energy (Bi Jie, Yang Blade) through official power (career, authority).

Huoyi Plea Breaks the Siege, One Battle Secures the Army's Heart

Li Yuan's army was blocked at Huoyi, facing a retreat. Li Shimin's tearful remonstrance stalled the retreat, and a stratagem provoked the besieging general Song Laosheng to fight, ultimately leading to a decisive victory over the Sui, capturing Huoyi and clearing the way toward Guanzhong.

Analysis
That year Dingchou aligns with the Dingmao big fortune. The subject's chart is旺, with Wood (官杀) as the favored element, foretelling nobility and power. The annual Dingchou combines with the Hour Pillar Jiayin, forming a 'double harmony'—a strong signal of mutual support between ruler and subjects. Meanwhile, the Chou Earth stirs the 午 Fire across the year and day pillars, activating the Yang Blade energy, the star of leadership in battle. The annual stars Tian Yi, Tai Ji, and Imperial Seal Nobleman converge, signaling key support from benefactors and official approval, with Tai Ji’s strategy and Imperial Seal’s execution. The Great Fortune’s Mao Wood, as Direct Official, gains ground, strengthening responsibility and strategic resolve (persuading the ruler not to retreat). The double harmony also triggers the Seven Killings in the hour pillar, amplifying the Yang Blade energy; this makes the energy 旺 and capable of a crushing assault, establishing his core military status after a single battle.

Star of the General Emerges at Shallow Water Plain; Direct Resource Suppressed, Setback

Li Shimin led his first campaign against Western Qin’s Xue Rengao; due to illness, he rested. His subordinates Liu Wenjing and Yin Kaishan disobeyed orders and fought without authorization, leading to a disastrous Tang defeat at Shallow Water Plain, with over half the forces lost.

Analysis
That year’s Wu Yin; The Wu Earth of the year acts as an inauspicious influence while Yin Wood Seven Killings is the favorable energy. The subject’s chart is旺, with Wood as the favored element to temper Earth. The year's Seven Killings comes into play, which would normally empower command and decisive action. However, the Dingmao fortune runs and the year's hour pillar Yin Wood Direct Official forms 午 Fire, creating 午卯 clash with the day pillar’s 午 Fire (the General Star). This clash directly undermines the Day Master’s foundation, causing instability and illness. Meanwhile, the Wu Earth clashes with Ren Water (the Hour pillar's wealth or paternal star), indicating subordinates disobeying orders and acting on their own, leading to military defeat. Although the campaign fails, the presence of the Seven Killings in the year's luck foreshadows future military maturity.

General Star Emerges at Shallow Water Plain; Direct Resource Suppressed, Setback

Li Shimin's first campaign against Western Qin's Xue Rengao; due to illness, he rested; subordinates Liu Wenjing and Yin Kaishan disobeyed orders and went into battle without authorization, resulting in a devastating Tang defeat at Shallow Water Plain, with more than half of the forces lost.

Analysis
That year's Wu Yin; The Wu Earth as the year's stem acts as an inauspicious factor while Yin Wood Seven Killings is the favorable energy. The Day Master is 旺; Wood is the preferred energy to ease Earth. The year's Seven Killings has ground, implying command and decisive battle is possible. Yet the fortune cycle is 丁卯; The great fortune's hour pillar Jia Wood Direct Official forms 午 Fire; The year/day’s 午 Fire clashes; This breaks the Day Master's foundation—午 Fire is the Day Master's Yang Blade and General Star—causing instability and illness. The earthly stems Wu Earth as peers clash with Ren Water, implying subordinates disobey orders and act on their own, causing military defeat. Although the campaign fails, the presence of Seven Killings in the year's luck foreshadows future military maturity.

A Decisive Battle at Qianshui Plain, Young Hero King Shakes Longxi

Li Shimin leads the campaign and decisively defeats Zong Luohou at Qianshui Plain, forcing Xie Rengao to surrender and capturing over ten thousand, thereby pacifying Longxi and strengthening a crucial Zhongzhou base for the Tang dynasty.

Analysis
That year, Li Shimin was in the Dingmao great fortune with Direct Seal, while the annual year is Wu Yin. The natal chart is a noble pattern of strong leadership and military talent, with Seven Killings as the favorable element. The annual Yin Wood Seven Killings is exactly when the chart's favorable Wood energy gains ground, greatly enhancing the Seven Killings power, signaling peak execution, decisiveness, and military command. At the same time, the yearly Yin and the chart's year/day Wu Fire form a Yin-Wu partial Fire formation, Fire being the 'Seal' star representing strategy, planning, and rear support. The fire formation's productive combination symbolizes military tactics and solid backers, forming a strong synergy. The luck pillar's Mao with the chart's Yin forms a mutual punishment; though it indicates inner pressure and undercurrents, it also sharpens the fierce drive of the Seven Killings, turning pressure into momentum on the battlefield. The year's Heavenly stem Wu strengthens his aura and team cohesion despite being a hindrance. In sum, the Seven Killings in a favorable, thriving ground, aided by the Seal energy, epitomizes how his extraordinary courage and military genius laid the foundations for his hegemony in one stroke.

Spearhead to Luoyang: Encirclement

Li Shimin leads an eastern campaign, strategically encircling Luoyang where Wang Shichong's forces hold, gradually seizing outer strongholds and cutting off the enemy's grain routes, leaving them isolated and vulnerable.

Analysis
That year coincides with the Gengchen luck cycle; the heavenly stems Geng Metal and the 'Food God' reveal themselves, merging with the month stem Yi Wood Official, signaling a major career opportunity and official recognition, favorable for expanding territory and earning merit.

Li Shimin personally leads 3,500 elite cavalry to guard Hulao Pass; in a lopsided victory, defeats Dou Jiande's army of more than a hundred thousand and captures its commander, clearing the major obstacle to the Tang dynasty's unification of the Central Plains.

Analysis

The heavenly stem Ding Fire (Direct Seal) combines with the time pillar Ren Water (partial wealth), transforming Wood into Official/Killer, strengthening the Seven Killers' power to command, and securing support from a noble patron (his father Li Yuan). The annual stem Xin Metal (ShangGuan) appears, colliding with the month stem Yi Wood Official, forming Bold actions challenging authority—indicative of unconventional, daring military actions such as ambushes to seize the enemy leader. The year Si Fire underpins the timing, bringing wisdom and decisiveness. The Yang Ren driving kill pattern reaches its peak, channeling the abundant Earth energy through Wood (Official/Kill) into unmatched leadership and battlefield prowess; a single battle cements the foundation of his dominance.

This is the chart's most favorable energy, signaling a notable rise in the career pattern and a concentration of power. The year's 辛 (Xin) metal Hurting Officer clashes with the monthly乙 (Yi) Wood Official (乙辛相冲); this clash signifies a strong disruption of the old order (Zheng Guo) and its replacement.

Li Shimin set a trap at the Xuanwu Gate, killed Crown Prince Li Jiancheng and Prince Li Yuanji, clearing the greatest obstacle to the pinnacle of power; subsequently he was named heir and wielded the empire's highest authority.

Analysis
This year falls under the戊辰 great fortune cycle (peer energy) with annual stem 丙戌. The chart forms a strong 'Yang Ren drives the Killing' pattern, signaling bold decisiveness. The fortune cycle and annual cycle clash (辰戌相冲), triggering upheaval. The annual stem 丙火 is an indirect support star, useful for adjusting the chart, yet also an unfavorable influence, pointing to strategic thinking and unconventional methods.

Dragon Soars to Nine-Five, Heralding the Zhenguan Era

Tang founder Li Yuan abdicated, Li Shimin officially ascended the throne in the ninth year of Wude according to the calendar (AD 626-09-04), becoming Taizong, era changed to Zhenguan, opening a famed prosperity in Chinese history.

Analysis
This year Li Shimin ascended to the throne, marking the peak of his career. The birth chart shows the noble pattern of Yang Ren driving the Killing star, with Seven Killings in use, indicating mastery of life-and-death power and imminent nobility. In the戊辰 luck cycle, the earth-branch辰 and the time-branch interact to form a Scorpio-like build that cusps the fire of巳;巳 fire is the 'lu' position for the day master 戊, while 巳 fire also activates the favorable 丙火 to regulate the timing and energize甲木 七杀, forming a贵气组合 of拱禄 and拱官杀, laying a strong base for ascendancy. In the flow year 丙戌, 丙火 serves as the regulating star and carries the 天官贵人, signaling official prominence and power. However, the earthly branch戌 clashes with the fortune's辰, triggering a fierce upheaval that corresponds to the power handover after the Xuanwu Gate incident, yet it also opens the官库, releasing power to the holder. It is in this complex pattern—unfavorable clashes paired with grounded favorable energies—that Li Shimin makes the ultimate leap from prince to emperor, inaugurating his era.

Heavenly Khan's Dominance Shakes the World, Grassland Sovereign Consolidates the Realm

Tang forces led by Li Jing annihilate the Eastern Turkic Khaganate in a single stroke. After the campaign, Northwestern tribes revere Li Shimin as 'Heavenly Khan', marking him as master of both the Central Plains and the steppes, forging an unprecedented imperial pattern.

Analysis
This year corresponds to the戊辰 great fortune and庚寅 year. The Day Master is a strong Wu Earth; it benefits from Wood (官杀) to restrain Earth. The year’s 寅木 is the Seven Killings, exactly what the chart enjoys, and is the source for the favorable Jia Wood to regulate the timing, giving strong power. The year’s heavenly stem 庚金 (Food God) and the month stem 乙木 (Direct Officer) are in conjunction (乙庚合), symbolizing the administrative/power star merging, implying that through strong military action (Food God representing strategy and action) supreme rulership is attained. The 寅木 of the year, together with 午 Fire in the calendar and day, forms a partial fire-wood pattern that triggers the Generals Star, strengthening authority and execution. The Heaven Virtue, Moon Virtue, and Noble Benefactors gather, signaling heavenly and earthly protection and broad public support. This is the peak expression of the Yang Ren drives Killing pattern, channeling the chart’s excess Earth Day Master energy through Seven Killings (military might and authority) toward expansion of territories and enduring meritorious achievements.
