The Origin of Laozi’s Cosmic “Chong” in Chu: Natural and Archaeological Evidence from Yingdu

The cosmology of Laozi’s Dao De Jing has long been regarded as an abstract metaphysical system, often divorced from its regional, ecological, and historical contexts. However, the core concept of “chong” (冲) possesses a unique generative and order-regulating function, whose philosophical formation is deeply linked to the natural civilization practices of the Chu region. This study systematically examines textual, toponymic, ecological, hydrological, and spatial archaeological evidence from the Chu heartland, the Yingdu civilization zone, and the Guodian Tomb No. 1 corpus. The findings indicate that the concept of “chong” originates from the ecological environment of valleys, forests, and riverine plains on the western banks of the Han River near Yingdu, characterized by flood regulation, buffering, and circulation, forming a low-entropy stable system. The governance practices of King Wen, King Cheng, and King Zhuang of Chu, along with the hydraulic engineering led by Sun Shuo’ao, translated these experiences into political institutions and social order, forming a low-intervention, adaptive model of state governance. The Guodian texts abstracted these Chu experiences into a systematic theory of cosmic generation, yin-yang harmony, and the operation of all things. The spatial concentration of the Yingdu civilization zone allowed political, ecological, and intellectual practices to intersect in situ, providing the real-world locus for philosophical abstraction. Comprehensive analysis demonstrates that Laozi’s cosmology is not merely a product of abstract reasoning but a universalized reflection of Chu’s natural civilization, embodying the intrinsic unity of nature, society, and cosmos. This study provides empirical grounding for interpreting the Dao De Jing and offers profound insights for contemporary ecological governance, social system management, and the transmission of natural civilization principles, suggesting that human civilization should aspire toward harmony with nature.
