Wow, coldpillow, thanks!
I've never had the opportunity to learn about other schools of Mingli before, and being able to learn about other points of view is providing me with valuable insights.
This is also the first time I've heard about 棄食就殺印 and 棄傷就殺印, but having read the webpage you provided, I get what they mean.
They have to do with the division between the Heavenly Stems and the Earthly Branches. Even though you're born as the Eating God or Hurting Officer (based on your birth month), you're thinking like the Partial Officer combined with a Seal because of the way your Heavenly Stems are shaped.
About the case in question, if I may add my opinion...
癸甲壬庚
酉寅午午
This chart is a Jia Wood Hurting Officer structure, born in the month of Wu Fire.
According to Ziping Mingli, the Hurting Officer structure is a reverse-use structure (逆用格). It takes Zheng Yin (正印) as the Xiangshen (Corresponding Spirit) and Rob Wealth (劫財) as the Gushen (구신, Supporting Spirit).
To function properly, this structure must have Zheng Yin to refine and control the Hurting Officer. That symbolizes obtaining an official qualification and entering the legitimate social order represented by the Direct Officer (正官).
If, instead of Zheng Yin, there is Pian Yin (偏印), then one grants legitimacy to oneself, developing personal talent and skill rather than formal credentials.
The Hurting Officer structure prefers a Day Master without roots, because when the Day Master is rooted, it desires Shishang (Wealth generation, 食傷生財) instead of following Zheng Yin to reach the Direct Officer.
In this chart, the Day Master is rooted and strong, so it wants to produce Wealth, meaning independence or self-employment. Yet there is no Wealth star present, and the Heavenly Stems display the opposite pattern of Guan-Yin mutual generation (官印相生).
Furthermore, the Month Pillar, representing career and domestic environment, combines Pian Yin + Hurting Officer, while there's the Indirect Officer instead of the Direct Officer.
In short, although the chart contains the Zheng Yin required for proper structure formation, too many conflicting conditions prevent it from functioning as a true Hurting Officer structure.
Thus, the 格 (structure) is broken; the person lives by mixed elemental tendencies rather than by the formal structure.
Given the details, the birth likely occurred after mid-Wu month. The combination of Jia Wood with Ding Fire within Wu indicates attempts to refine Geng Metal and You Metal, pointing to technical or vocational schooling.
However, the Pian Yin dominating the thought pattern of the Month Pillar shows that career and family circumstances are controlled by subjective preference.
While Zheng Yin aligns the self to authority, Pian Yin makes authority conform to the self, making the self preferring to work when comfortable, or being constrained by home obligations (for example, caring for elderly parents).
Overall:
Strong Day Master → prefers self-driven work.
No Wealth → lacks business or monetary focus.
Dominant Pian Yin → subjectivity and irregular rhythm.
Structure broken → technical, flexible, self-determined life path rather than official or institutional one.
