The ethical foundation of companionate marriage and shared adversity, building the most resilient micro-community for domestic and societal stability.

In a classical natural economy with extremely low risk resistance, the systemic environment was full of unpredictable variables and disorderly disasters — famine, warfare, plague. A single isolated social node, when struck by such system-level shocks, could be instantly annihilated. To raise the baseline probability of survival, the smallest viable unit had to form the tightest possible two-person alliance to share the formidable burden imposed by the environment. The system urgently needed a binding norm capable of resisting external rupture.

Moistening each other with saliva (xiang-ru-yi-mo) is an extraordinarily resilient micro-alliance mechanism against disorder. It goes far beyond the needs of animal reproduction, insisting that in adversity — when resources are utterly depleted and the situation is desperate — husband and wife must execute absolute resource sharing and mutual spiritual support. This is a mechanism that irreversibly fuses two independent capacity nodes. Under severe conditions, any reservation of self-interest or calculation of sunk cost by either party would cause the alliance to disintegrate instantly. The system therefore compels both sides to lay down all their cards and make the highest-grade trust pledge. This seamless welding and life-or-death compact between micro-nodes not only dramatically raised the survival rate of the most basic living unit, but also provided the vast, heavy structure of the agrarian empire with thousands upon thousands of highly pressure-resistant, nearly indestructible bottom-layer physical load-bearing units.

Mutual devotion works through repeatable structure. Through learning, imitation, institutionalization, and daily use, what began as localized experience hardens into a stable civilizational capacity. This process allows it to cross eras and continue shaping later ideas and practices. It also turns this chapter from mere historical knowledge into a lens for observing how civilizations accumulate capabilities.

Mutual devotion also shapes different groups of people. Scholars, artisans, families, officials, merchants, soldiers, and local communities may all participate in its formation and spread at different levels. The husband-wife covenant and family micro-foundation of shared hardship and unwavering togetherness. This is why it connects meaningfully with other chapters. It has its own functional boundaries, yet it also generates echoes outward in ideas, institutions, and techniques.

Marriage is a key node in Chinese civilization. The ethical foundation of companionate marriage and shared adversity, building the most resilient micro-community for domestic and societal stability. Its importance lies not only in naming an idea, but in showing how people, families, social order, and civilizational values connect. It gives the reader a first doorway into the logic of this chapter. Through it, abstract values enter concrete life.
