Use when persuading a powerful adversary to change their military or political course of action. Employs historical analogies, risk analysis, and alternative alliance proposals to redirect an opponent's strategy.

Use when responding to territorial demands from a powerful adversary or deciding how to deploy contested resources. Redirects resources that would be conceded to the aggressor toward the aggressor's enemies instead, building counter-alliances that deter future demands and strengthen negotiating position.

Use when experiencing talent attrition or when followers perceive hypocrisy between stated values and leader behavior. Diagnoses the root cause through direct inquiry, then requires a visible personal sacrifice to demonstrate that talent is valued above personal pleasures or possessions.

Use when restoring a dismissed official to power or leveraging rival factions for political rehabilitation. Creates urgency by approaching rival powers with the dismissed leader's value, then returns to the original state with evidence of the rival's recruitment attempt to force restoration.

Use when hosting guests, managing dependents, or building loyalty through hospitality. Provides equal treatment regardless of status, records personal details via a scribe behind a screen, sends follow-up gifts to guests' families, and resolves perceived slights through transparent demonstration.

Use when implementing comprehensive state reforms or transforming governance systems. Follows Shang Yang's model — mutual responsibility (什伍), family structure reform, merit-based ranks replacing hereditary privilege, and standardized weights, measures, and legal codes.

Use when taking command of new troops or establishing organizational authority. Follows Sima Rangju and Sun Wu's methods — enforcing punctuality penalties against high-ranking offenders, asserting 将在军君令有所不受, and demonstrating that rules apply equally regardless of status.

Use when facing a numerically superior enemy or planning ambush warfare. Employs Sun Bin's staged retreat (reducing cooking fires from 100,000 to 30,000) to feign mass desertion, plus asymmetric resource allocation (sacrifice weak vs. strong, deploy strong vs. middle) for 2-1 victories.

Use when a powerful minister faces suspicion from a ruler or when navigating dangerous court politics. Deploys four survival strategies — hostage-sending, deliberate self-pollution (自汙), graceful punishment acceptance, and honor-declining — to reduce perceived threat level.

Use when building popular support or consolidating political power through economic generosity. Implements asymmetric resource distribution — collecting with small measures, distributing with large — to cultivate mass loyalty and clan influence over time.

Use when establishing governance over newly conquered or acquired territory. Based on Zhou Gong's advice to Kang Shu for ruling former Shang lands: seek local wisdom, study prior regime failures, practice benevolent rule, establish legal frameworks, and appoint virtuous officials.

Use when performing solemn divination rituals to seek ancestral guidance for critical decisions. Follows Zhou Gong's model: sacred space preparation, jade disc and gui tablet adornment, oracle bone consultation, and sealed documentation in golden chest.

Use when calculating calendars, determining seasonal timing, or establishing the correct 正朔. Covers leap month intercalation using the 19-year Metonic cycle, solstice measurement via shadow length (晷景), and dynastic calendar differences.

Use when planning irrigation canals, flood control, or water resource management for agriculture. Applies Yu's principle of channeling over blocking (疏导优于堵塞) and includes the Zheng Guo Canal case study.

Use when analyzing feudal power structures or ranking noble titles. Classifies ranks using the Zhou dynasty five-tier system (公侯伯子男) and determines appropriate land grants based on merit, lineage, and strategic need.
