Chapter 1: The Name Qingming—The Meaning of Clarity Between Heaven and Earth

The naming of a solar term is never accidental. The names of the twenty-four solar terms are refined summaries by our ancestors of the laws of heaven and earth, with each name condensing meticulous observation of nature and a profound understanding of cosmic order. We must first ask: What is "Qing"$5 What is "Ming"$6 What celestial landscape and spiritual state do they signify when joined together$7

Section 1: Examining "Qing"—Clarity, Purity, and the Essence of the Heavenly Dao

The original meaning of the character "Qing" relates to water. In Shuowen Jiezi, Xu Shen writes: "Qing means clear/bright. It describes the appearance of clear water. It is composed of the radical for water and the phonetic element qing." The scholar Duan Yucai adds: "To be bright is to be clear. Only after it is clarified can it be bright." Thus, the original meaning of "Qing" is the transparency of water. Still water is clear; agitated water is turbid. This simple physical observation was elevated in Chinese culture into a virtue of the Heavenly Dao and a mark of human character.

Why did "Qing" rise from a property of water to a virtue of Heaven$8 In ancient cosmology, when Heaven and Earth first formed, the clear and the turbid separated: the light and clear qi ascended to become Heaven, and the heavy and turbid qi descended to become Earth. Huainanzi states: "The clear and the light swirled and became Heaven; the heavy and the turbid condensed and became Earth." This defines "Qing" as the fundamental attribute of Heaven. Heaven is Heaven precisely because its qi is clear.

Laozi (Chapter 39) says: "Of those in antiquity that attained the One: Heaven attained the One and became clear; Earth attained the One and became tranquil..." Here, Laozi identifies "Qing" as the virtue of Heaven. Heaven is clear because it has obtained the "One," which is the Dao. The operation of the Dao is unobstructed and unpolluted; this is the highest state of "Qing."

Furthermore, in Taoist self-cultivation, Laozi (Chapter 15) asks: "Who can be turbid, yet by settling, gradually become clear$9" The human heart is like water; when disturbed, it is turbid; when still, it is clear. The art of the Dao lies in this transformation, and the key is "stillness."

In the Confucian tradition, "Qing" signifies moral purity. Mencius described Bo Yi as the "most clear of the sages" (Mencius, 5B), referring to his refusal to compromise his integrity in a corrupt world. When used to name a solar term, "Qing" points to the limpid, clean, and transparent atmosphere of the world at this moment, as the turbid qi of winter dissipates and the clear, yang qi permeates the world.

Section 2: Examining "Ming"—Brightness, Manifestation, and the Clarity of Things

If "Qing" emphasizes the clarity of the atmosphere, "Ming" focuses on the radiance of phenomena.

"Ming" is composed of the characters for "sun" and "moon." Shuowen Jiezi notes: "Ming means to illuminate." In the ancient view, the sun and moon are the greatest sources of light. The I Ching says: "The way of the sun and moon is that they are constant and bright." Without this light, all things would be hidden in darkness, unrecognizable. "Ming" is thus the prerequisite for cognition and the foundation of order.

In Confucianism, "Ming" signifies the ability to discern right from wrong. Confucius said that one who remains unswayed by slander is "clear" (Lunyu, 12.10). In Taoism, Laozi states: "Knowing the constant is 'Ming'" (Chapter 16), meaning to discern the unchanging laws of the Dao. "Knowing others is intelligence; knowing oneself is 'Ming'" (Chapter 33).

When applied to the season, "Ming" conveys that all things have become manifest and visible. Winter's haze has cleared, days are lengthening, and the earth is illuminated by the spring sun. Everything is revealed; this manifestation is the phenological expression of "Ming."

Section 3: Synthesis—The Atmosphere of Heaven and the State of the Heart

"Qing" describes the qi, and "Ming" describes the phenomena. When the qi is clear, there is no obstruction; when phenomena are bright, there is no concealment. This is the most beautiful time of the year.

This leads to a profound cultural phenomenon: in Chinese thought, Nature and Man are mirror images. The clarity of Heaven reflects the clarity of politics and the clarity of the human mind. The "Unity of Heaven and Humanity" is specifically manifested here: humans, as beings between Heaven and Earth, should cultivate a "clear and bright" state of mind—clearing internal distractions and discerning right from wrong, just as the natural world clears itself of winter’s impurities.
