A Critical Examination of the Qi Transformation of the Twelve Earthly Branches' Six Conjunctions

This paper strips away the veneer of divination and numerology to return to Pre-Qin astronomy and cosmology, critically examining the true nature of the Six Conjunctions (Liu He) among the Twelve Earthly Branches (Zi Chou, Yin Hai, Mao Xu, Chen You, etc.). It focuses on analyzing the essential 'astronomical copulation' of the Six Conjunctions and the philosophical implications—such as concealment, generation, refinement, and transformation—embedded within their 'Qi Transformation' (Hua Qi).

A Critical Examination of the Qi Transformation of the Twelve Earthly Branches' Six Conjunctions

II. In-Depth Analysis from the Ancient Perspective

This Six Harmony involves the ancient worship of the Dragon and Phoenix totems.

  1. Astronomical Deconstruction of the Dragon-Phoenix Auspice:
    • Chen is the Dragon, located in the Eastern Kang (亢) Mansion of Metal Dragon. You is the Rooster (a common term for the Phoenix), located in the Western Mao (昴) Mansion of the Sun-Rooster.
    • The harmony of Chen-You is essentially the consolidation of Metal Qi.
    • Although Chen is in Spring, it stores Yi Wood, Gui Water, and Wu Earth. You is Xin Metal.
    • When the Dipper points to Chen (Qingming Festival), the Sun resides in You (near the Autumnal Equinox).
    • Why transform into Metal$8 At this point, the Sun in the West (You) is supremely strong, and Metal Qi dominates the Heavenly Dao. Although Chen Earth is moist, it encounters the extremely potent Qi of pure Metal. The Yi Wood within Chen is purged by the Xin Metal, the Gui Water is absorbed and used to cleanse the Metal vessel, and the Wu Earth fully devotes itself to generating Metal.
  2. The Mechanism of Transforming into Metal—Alloying and Refinement:
    • This is not merely Earth generating Metal; this is a process of "Alloying" (合金).
    • The Kao Gong Ji (考工记, The Record of Endeavors of the Craftsmen) discusses casting metal, which requires an earthen mold (Chen as the mold) and molten metal (You as the bronze liquid). Only when combined can a great artifact (like a bronze bell) be formed.
    • The Meaning of Cong Ge (变革, Change/Transformation): The Shangshu – Hongfan states: "Metal is called cong ge (following and changing)" (金曰从革). Ge means transformation. The harmony of Chen-You means forcibly turning the generative Qi of Spring into the austere execution and transformative Qi of Autumn.
  3. Quotation and Reflection:
    • In the Huangdi Neijing, the transformation of Chen-You into Metal corresponds to "Dryness Qi" (燥气). Dryness overcomes moisture.
    • Historical Analogy: Warring States strategists often used "Chen-You" to symbolize a strategic alliance. Chen represents the multitude, and You represents the leader. Like all stars orbiting the moon, they achieve dominance through unity.

Conclusion The Harmony of Chen-You transforming into Metal is the "Metal of Austere Execution" (肃杀之金), and also the "Metal of Transformation." It signifies the establishment of authority and the purging of heterogeneous Qi. The Earth of Chen abandons its own vitality (Wood) to achieve the sharp edge (锋芒, fēng máng) of You Metal.
