Use when analyzing whether virtue correlates with worldly success or questioning cosmic justice (天道). Compares virtuous sufferers (伯夷, 颜回) against prosperous villains (盗跖) using Sima Qian's method to assess 天道无亲常与善人 and inform ethical decision-making.

Use when evaluating candidates for government positions or assessing character suitability. Applies Li Ke's five-lens framework: 居视其所亲, 富视其所与, 达视其所举, 穷视其所不为, 贫视其所不取 to reveal values, generosity, judgment, principles, and integrity.

Use when persuading a resistant authority figure to take difficult but necessary action. Employs a gradual empathetic approach: build rapport through shared humanity, introduce topics indirectly, present arguments through historical examples, appeal to long-term interests, and let conclusions be self-evident.

Use when evaluating locations for settlement, refuge, or strategic positioning. Covers geographic advantages, political landscape assessment, population disposition analysis, and long-term power projection, with decision rules to reject sites near rising powers and favor those with alienated populations.

Use when assigning leadership roles to maximize team effectiveness based on relative strengths. Follows Fan Li's advice to Goujian: directly compare each advisor's capabilities across domains (military vs. civil) and assign primary roles where each person excels most.

Use when dissuading a victorious leader from overextending through further military action. Employs the 'painting feet on a snake' (画蛇添足) analogy to demonstrate that additional gains risk losing everything already achieved, and frames withdrawal as preserving honor.

Use when analyzing last-resort strategies against existential threats where all conventional and diplomatic options have failed. Covers agent recruitment, pretext creation, close-range execution, and critical risk assessment of retaliatory consequences.

Use when deciding whether to launch a military campaign or evaluating battle readiness. Applies Sun Wu's advice to King Helu of Wu: assess troop fatigue (民劳), alliance potential, enemy leadership weaknesses, and multi-pronged coordination.

Use when interpreting celestial phenomena for governance guidance or predicting earthly events. Tracks the five planets (五星) against 28 constellations (二十八宿) and applies the response framework: 日变脩德, 月变省刑, 星变结和.

Use when analyzing rebellion risk or diagnosing why uprisings succeed or fail. Applies the principle 安民可与行义而危民易与为非 to assess popular contentment vs. endangerment using economic, legal, and safety indicators. References Chen She's rebellion.

Use when evaluating the feasibility of a long-distance surprise military attack. Assesses distance risks, intelligence reliability, supply line vulnerabilities, and contingency planning. Based on Qin's failed attack on Zheng as a cautionary example.

Use when recruiting talented individuals from rival states through discreet negotiation. Based on Duke Mu's recruitment of Baili Xi, guides target identification, concealment of intentions, low-value exchange tactics, and capability assessment.

Use when selecting or vetting a successor for leadership. Applies a multi-phase evaluation combining character tests, progressive responsibility assignment, regency trials, and public acceptance before formalizing succession.

Use when evaluating official performance or deciding promotions and demotions. Implements a three-year cycle assessment over nine years, using documented achievements to determine advancement (陟) or removal (绌).
