An In-depth Interpretation of Lixia in the Twenty-Four Solar Terms: Philosophical, Philological, and Astronomical Perspectives
This article provides an in-depth analysis of Lixia (the Beginning of Summer) through the lenses of pre-Qin Confucian and Daoist philosophy, etymological roots, and astronomical observation, elucidating its significance as the critical juncture where the cosmic momentum shifts from "birth" to "growth." By examining the evolution of the character "xia" (夏) and the movement of the star Antares, the study reveals the profound wisdom behind the ancient mandate of "respectfully bestowing the seasons" and the harmonious worldview of unity between humanity and the cosmos.
