Use when strategic factors favor action but divination or omens suggest failure. Applies Taigong's counsel at the Battle of Muye: assess enemy vulnerability and cause justice independently of superstitious signs to avoid paralysis.

Use when responding to urgent warnings about missed opportunities or overcoming complacency. Applies Taigong's innkeeper lesson: 时难得而易失 (timing is hard to gain and easy to lose) — act immediately through the night if necessary.

Use when deciding whether to honor a commitment after circumstances change, especially after the recipient's death. Applies Ji Zha's sword-promise principle: internal assent creates moral obligation that transcends death.

Use when managing a multi-domain crisis or coordinating emergency response across military, diplomatic, and administrative fronts. Delegates specific responsibilities to trusted subordinates while maintaining strategic oversight.

Use when performing Feng and Shan sacrifices (封禅礼仪) to establish divine endorsement of imperial rule. Covers prerequisites, ritual sequence at Mount Tai, and proclamation steps for Emperor Wu's legitimacy model.

Use when transitioning from conquest to stabilization or diagnosing dynastic failure. Applies the principle that 取与守不同术也 (taking and keeping power require different methods), shifting from military force (诈力) to benevolence and adaptability (顺权).
