Birth Time Verification
This page uses the Chou hour for Li Shimin, giving the four pillars as Wu Wu, Yi Chou, Wu Wu, Gui Chou. The cited BaZi source gives a Chou-hour birth on a Wu Wu day, and the local chart check for 599-01-23 02:00 matches the same year, month, day and hour pillars. The Chou hour matters. Both the month and hour branches are Chou, while the Wu Earth Day Master also sits on a Wu Fire branch. Earth and Fire are therefore very strong. Yi Wood in the month stem and Gui Water in the hour stem give the chart two ways to breathe: Yi Wood points to order, rank and governing rules, while Gui Water points to strategy, resources and the ability to listen. His movement from military force into government cannot be read from heavy Earth alone. It needs this Wood-and-Water opening.
Core Analysis
Li Shimin's chart is Wu Wu, Yi Chou, Wu Wu, Gui Chou. The Wu Earth Day Master is reinforced by another Wu stem, sits on a Wu Fire branch, and is further weighted by two Chou branches. The local chart check reads the Day Master as extremely strong, with Wood useful and more Earth unfavourable. The most important visible pattern is Yi Wood Authority in the month stem and Gui Water Wealth in the hour stem. Yi Wood represents order, rank, restraint and the grammar of rule. Gui Water represents resources, strategy, counsel and later governance. When Earth is too thick, the person can become rigid. With Water and Wood showing, there is room for a warrior to hear advice and build institutions. The natal chart also has Chou harming Wu. Two Chou branches press against the two Wu branches, so family, succession and internal power never look smooth. In 626, the Wu Chen luck pillar met the Bing Xu year. Chen and Xu clashed, Chou and Xu formed punishment, and the succession struggle erupted as the Xuanwu Gate Incident. In the Zhenguan years, the useful Water and Wood side became more visible through counsel, talent selection and administrative order.
Traits

Instinct for Order
Yi Wood Authority in the month gives a clear concern for rank, law and governing structure.
Uses Resources Well

Kinship Pressure

Timeline
Each year shows the event, luck pillar, annual pillar, relations, and interpretation for direct comparison.
Joined Li Yuan’s Jinyang Uprising
Li Shimin joined his father’s uprising and entered the struggle at the end of the Sui dynasty.
In the Ding Mao luck pillar, Ding Fire Resource supports the self, while Mao Wood gives rank and direction. The Ding Chou year repeats the Chou pressure around family and military power. This was not merely private boldness. It came through a father-son bloc, political legitimacy and a military opening.
Won at Hulao and Settled the Central Plains
Li Shimin defeated Dou Jiande and Wang Shichong, making Tang control of the central plains far more secure.
The Ding Mao luck pillar strengthens the Authority side, linking victory with rank and military legitimacy. In 621, Xin Metal appears as Hurting Officer, and Si with Chou pulls toward Metal, sharpening tactics and decision. It is risky, but in a war setting that sharpness can break a deadlock.
Xuanwu Gate and Accession
The Xuanwu Gate Incident broke out. Li Shimin was then made crown prince and soon became emperor.
The Wu Chen luck pillar brings Companion energy, which often highlights brothers, peers and direct power competition. In the Bing Xu year, Xu clashes with Chen and punishes Chou. Fire and Earth press an already heavy chart, matching the severity of the succession crisis.
Began the Zhenguan Reign
Li Shimin adopted the Zhenguan reign title and began building a more stable political order.
The Wu Chen luck pillar still carries heavy Earth, but the Ding Hai year brings Hai Water. Water can moisten thick Earth and help Wood function. The early Zhenguan emphasis on counsel, restraint and institutions fits the useful Water-and-Wood side of the chart.
Died at Cuiwei Palace
Li Shimin died in the twenty-third year of Zhenguan.
In the Geng Wu luck pillar, Wu Fire repeats the day branch and intensifies the natal Chou-Wu harm. The Ji You year adds Earth while You combines with Chou toward Metal, increasing both pressure and leakage. In traditional longevity reading, Fire pressing the body, heavy Earth and Metal draining the chart all point to concentrated health depletion.
