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).

Chapter 7: General Discussion—The Universe Map of Ancient Forerunners as Seen Through "Qi Transformation"
Observing the Qi Transformations resulting from the Six Harmonies of the Twelve Terrestrial Branches, we easily discern a rigorous "Ancient Natural Philosophy Logic":
- Zi-Chou Transform into Earth: A simulation of the Winter Solstice's severe cold, where all things return to their roots and are sealed.
- Yin-Hai Transform into Wood: A simulation of Water generating Wood, the breaking of the kernel, and the emergence of life.
- Mao-Xu Transform into Fire: A simulation of the agitation between Spring generation and Autumn execution, generating kinetic energy (Thunder-Fire).
- Chen-You Transform into Metal: A simulation of Earth generating Metal, the autumnal harvest, and transformative austerity.
- Si-Shen Transform into Water: A simulation of the condensation resulting from the clash between heat (Fire) and cold/metal, resulting in a liquid state.
- Wu-Wei Transform into Fire/Earth: A simulation of the Summer Solstice's extreme Yang, where light and heat coalesce.
Final Philosophical Reflection
Why did the pre-Qin classics place such importance on "Harmony and Transformation"$15 Because "solitary Yin cannot generate, and isolated Yang cannot flourish." If the Terrestrial Branches do not harmonize, they remain merely isolated temporal markers; once harmonized, they produce "Transformation" (huà), which means change and flow. This is the core idea of the I Ching: That which is called Yi (Change) is ceaseless generation (生生之谓易).
The transformation of the Six Harmonies is, in essence, the attempt by ancient forerunners to capture the law of Energy Transformation in the cosmos using a symbolic system. Wood transforms into Fire, Fire into Earth, Earth into Metal, Metal into Water, and Water into Wood, cycling endlessly, without beginning or end.
Studying the Harmony and Transformation of the Terrestrial Branches is not merely studying numerology; it is using it as a lens through which to glimpse that magnificent era when "Man walked alongside the Spirits, and Heaven and Earth conformed to the same law." Behind those seemingly superstitious maxims lies the ancients' simplest yet most profound grasp of the truths concerning astronomy, geography, physics, and meteorology.
