Chapter 2: Fundamental Differences in Analytical Logic

Although the charts look the same, the thinking logic (Algorithm) during interpretation is completely different. It's like using the same deck of cards: the rules for playing "Poker" and "Bridge" are entirely different.

2.1 Selection of Useful God: Variable vs. Fixed

In the Hourly Chart, the Useful God (Yong Shen) "turns with the matter."

Asking for wealth: Look at Jia Zi Wu and the Sheng Men (Life Gate).
Asking for work: Look at the Kai Men (Open Gate).
Asking for exams: Look at the Tian Fu Star and Ding Wonder.
Asking for health: Look at the Tian Rui Star.
Core Logic: We look for the symbol representing "this matter" in the chart and analyze its relationship with the symbol representing "me" (Day Stem).

In the Destiny Chart, the Useful God is "relatively fixed."

Day Stem: Always represents the owner of the destiny (the person themselves). This is the absolute core and the base point of analysis.
Zhi Fu: Represents innate luck and guardian spirits.
Zhi Shi Gate: Represents the lifelong acting style and career inclination.
Year Stem: Represents parents and ancestral property.
Month Stem: Represents siblings and peers.
Hour Stem: Represents children, subordinates, and late-life luck.
Core Logic: We construct a family and social network centered on the "Day Stem" in the chart and analyze the stability of this network structure.

2.2 Interpretation of Palace Relationships: Production/Control vs. Prosperity/Decline

The Hourly Chart emphasizes "Action" and "Production/Control" (Sheng/Ke).

In the Hourly Chart, we place great importance on the production and control relationships between palaces.
For example, asking about business: Sheng Men (Profit) produces Day Stem (Me) -> Great Auspiciousness, wealth is gained.
Sheng Men controls Day Stem -> Seeking wealth is hard, or even financial loss.
Logic: This is a logic of "Energy Transfer." If energy flows to me, I benefit; if energy clashes with me, I suffer damage.

The Destiny Chart emphasizes "Stillness," "Prosperity/Decline" (Wang/Shuai), and "Structure."

In the Destiny Chart, simple production/control is not the most important factor. What matters most is one's own state (Prosperity/Decline) and the combination of the structure.
For example, if the Day Stem falls in the Kan Palace (Water element). If born in winter (Water is prosperous), the person's own energy is strong. Even if they encounter control or draining, they are not afraid; instead, they can handle wealth and officialdom.
If born in summer (Fire is prosperous), the Day Stem Water is in a "Trapped/Dead" state, and the self is weak. At this time, even if there is wealth (Fire), they cannot hold it, and it may lead to disaster caused by wealth.
Logic: This is a logic of "Constitution Assessment." First, check if the car (the person) has enough horsepower (Prosperity/Decline), then check if the road conditions (Structure) are good.

2.3 Focus of Symbol Meanings: Concrete vs. Abstract

The symbol meanings in the Hourly Chart are very concrete (Image-based).

Tian Peng Star: When predicting events, it may represent a thief, a robber, an embezzler, or specific water conservancy projects, black objects.
Shang Men: May represent a car accident, injury, debt collector, or police.

The symbol meanings in the Destiny Chart are more abstract (Temperament/Profession-based).

Tian Peng Star: In the Destiny Chart's Day Stem Palace, it usually does not mean the person is a thief, but represents that the person is bold, extremely intelligent, adventurous, and speculative. Professionally, they may be suitable for trade, shipping, or high-risk investments.
Shang Men: In the Destiny Chart's Day Stem Palace, it represents that the person is straightforward, easily offends others, and competitive. Professionally, they may be suitable for military/police, sports, or even being a surgeon.
