Diagram of the Standard Five Elements Formation of the Miscellaneous Military Schools

original: 雜兵家正五形陣圖 — Zábīngjiā Zhèng Wǔxíng Zhèn Tú. The "Miscellaneous Military Schools" were tactical scholars who synthesized various ancient strategies into practical systems.

This diagram illustrates the Five Elements (original: 五行 — Wǔxíng) theory applied to the battlefield. In this system, each cardinal direction and the center are governed by a specific element, which influenced everything from the color of the unit's banners to their specific tactical responsibilities. The formation is a "quincunx"—a geometric pattern consisting of five points arranged in a cross.

original: 火 — Huǒ. Positioned at the top, representing the South and the Front. Fire symbolizes aggression, speed, and the "vanguard" of the army.

original: 木 (Wood), 土 (Earth), 金 (Metal). Wood (left) represents the East and growth. Earth (center) represents the core of the army and the commander's headquarters. Metal (right) represents the West, associated with harvest and the sharpness of weapons.

original: 水 — Shuǐ. Positioned at the bottom, representing the North and the Rear. Water symbolizes the depth, stillness, and the reserve forces held in the back.

The Five Elements Formation (original: 五形陣 — Wǔxíngzhèn) allowed commanders to move their troops according to the "Cycles of Generation and Overcoming." For example, if an enemy used a "Fire" style attack (fast and aggressive), a commander might counter with "Water" tactics (fluidity and encirclement). This system provided a mnemonic framework for complex maneuvers, ensuring that soldiers and officers knew their roles based on cosmological principles they already understood from daily life.
