This essay strips away the veneer of divinatory numerology to return to pre-Qin astronomy and cosmology, offering a rigorous investigation of the true nature of the Six Conjunctions of the Twelve Earthly Branches — Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, and the rest. It focuses on the astronomical 'conjugation' essence of the Six Conjunctions, and the philosophical implications — sealing and storing, sprouting and rising, refining and transforming, revolution and change — concealed behind their 'qi transformations.'

This article offers a philological and philosophical examination of the Qingming solar term, exploring the cosmic significance and humanistic ideals embodied in the concepts of "clarity" (qing) and "luminosity" (ming).
