A Clap of Spring Thunder: The Awakening of Life and the Way of Dormancy in the Jingzhe Solar Term
This article offers a deep reading of Jingzhe (Awakening of Insects) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. Through an examination of the historical renaming from 'Qizhe' to 'Jingzhe,' an analysis of how spring thunder rouses hibernating creatures, and the cosmic vision of the Zhen (Thunder) hexagram's 'the sovereign emerges from Zhen' in the Book of Changes, the essay reveals the critical threshold at which life transitions from dormancy to vigorous action, illuminating the ancient Way of bending and stretching to preserve one's being.

Chapter Eleven: Cultivation of Body and Mind -- Nourishing Health and the Stirring of Spirit at Jingzhe
I. Following Yang Qi: The Fundamental Principle of Health Cultivation
The fundamental principle of health cultivation at Jingzhe can be stated in four words: follow the yang qi.
The Yellow Emperor's Inner Classic (Huangdi Neijing), in the "Great Treatise on Regulating the Spirit in Accordance with the Four Qi" (Siqi Tiaoshen Da Lun), though compiled somewhat later, has its health-cultivation thought deeply rooted in pre-Qin ideas of the Heaven-humanity relationship. On the Way of nourishing life in the three months of spring, it says:
"The three months of spring are called 'bursting forth and display.' Heaven and earth together generate; all things flourish. Retire late and rise early; stride broadly through the courtyard; let the hair hang loose and relax the body, so that the will may be born. Generate and do not kill; give and do not seize; reward and do not punish. This is the response to the qi of spring, the Way of nourishing life."
This passage is the guiding principle for spring health cultivation (which naturally includes Jingzhe). "Bursting forth and display" (fa chen) -- pushing out the old and displaying the new; all things in spring unfurl what has been stored. "Heaven and earth together generate; all things flourish" -- both heaven and earth are in their generative mode, and all things thrive accordingly. In such a season, what should a person do$17 "Retire late and rise early" -- one may go to bed a little later but should rise early, in accord with the lengthening daylight and the rising yang qi. "Stride broadly through the courtyard" -- take leisurely walks in the courtyard, stretching the body. "Let the hair hang loose and relax the body" -- wear the hair unbound, relax the frame, avoid constraint. "So that the will may be born" -- let one's intention and spirit come alive.
Why "let the hair hang loose and relax the body" and "so that the will may be born"$18 Because spring is a season of generation and expansion. Correspondingly, the human body and spirit should be in a state of expansion, generation, and freedom from constraint. If in spring one still bundles up tightly and contracts the spirit as in winter, one contravenes the Way of Heaven's "generation" in spring, to the detriment of health. At Jingzhe, when yang qi surges, the body's yang qi also rises accordingly; this is precisely the time to let body and mind unfurl, allowing vitality to grow freely.
II. "Generate and Do Not Kill; Give and Do Not Seize": The Unity of Nourishing Health and Nourishing Virtue
The Great Treatise continues: "Generate and do not kill; give and do not seize; reward and do not punish."
On the surface these lines discuss health cultivation, but in reality they unify the nourishing of body with the nourishing of virtue and of mind. They tell us that health cultivation at Jingzhe is not merely physical (rising early, walking, stretching) but also pertains to character and disposition -- one should cultivate attitudes of "generating," "giving," and "rewarding," and set aside attitudes of "killing," "seizing," and "punishing."
What profound insight! It reveals a truth: body and mind are one; health cultivation cannot be separated from the cultivation of the heart. A person harboring thoughts of harshness, grasping, and severity, even if they rise early and walk daily, will struggle to achieve true health. Conversely, a person whose heart is full of generativity, generosity, and warmth, attuned to the generative qi of spring, will naturally tend toward health. At Jingzhe, when heaven and earth brim with vitality, if one can fill one's heart with the same vitality -- magnanimity, generosity, encouragement, aspiration -- this itself is the finest health cultivation. This is the essence of the Chinese tradition of "nourishing both form and spirit" and "nourishing health by first nourishing the heart."
III. Thunder and the Heart-Mind: Emotional Cultivation at Jingzhe
Jingzhe takes thunder as its central image, and in the theory of Chinese medicine, thunder bears subtle connections with the "heart" (xin) and the "liver" (gan). From the perspective of emotional cultivation, Jingzhe has its special considerations.
On one hand, spring belongs to Wood, and Wood corresponds to the liver. The liver governs the free flow of qi (shuxie) and smooth openness (tiaoda); it delights in ease and resents depression. At Jingzhe, the liver qi rises with yang qi, reaching its most vigorous state but also its greatest need for release. If at this time the emotions are depressed and the liver qi stagnates, various discomforts may arise. Thus, health cultivation at Jingzhe requires particular attention to maintaining cheerful spirits and emotional openness, allowing the liver qi to rise smoothly, just as plants should be allowed to grow freely. This again confirms the wisdom of "so that the will may be born" -- letting the will and emotions come alive and expand is the core of Jingzhe health cultivation.
On the other hand, Jingzhe's thunder reminds us of the earlier discussion of "fearful self-examination" and "not losing the ladle and libation." Thunder symbolizes sudden upheaval and shock from the outside world. In the context of health, this tells us that when faced with the sudden reversals, pressures, and stimuli of life (life's "thunderclaps"), we should cultivate a spirit of calm composure, not allowing external upheavals to disturb our inner equilibrium. To maintain "stillness" amid "startlement," to hold "composure" amid "movement" -- this is not only a moral cultivation but also a Way of nourishing health, for violent, prolonged emotional swings are most injurious to the body. At Jingzhe, one must at once follow yang qi by surging and stretching forth, and within that surging hold fast to inner steadiness -- this is the dialectical unity of body-mind cultivation at this solar term.
IV. Diet and Daily Life: The Specific Practices of Jingzhe Health Cultivation
In the specifics of diet and daily routine, Jingzhe health cultivation has its own particular considerations, all derived without exception from the fundamental principle of "following the heavenly seasons."
In daily routine, as noted above, one should "retire late and rise early," in accord with the lengthening daylight; "stride broadly through the courtyard," exercising moderately, stretching the body to assist the rising of yang qi. Jingzhe, when yang qi surges, is an excellent time for outdoor activity and excursions into nature; prolonged confinement indoors and lethargy are inadvisable.
In diet, the traditional health cultivation principle at Jingzhe is to "reduce sourness and increase sweetness, to nourish the spleen qi." Why$19 Because in spring the liver qi is already naturally exuberant (Wood is in ascendancy), and the sour taste enters the liver. If one eats too much sour food, the liver qi becomes excessive and will overwhelm the spleen-earth (Wood conquers Earth). Therefore, one should actually reduce sour flavors and increase sweet ones, supplementing the spleen qi to harmonize liver and spleen. This is a concrete application of Five Phases conquest theory in health cultivation -- adjusting diet to balance the qi of the organs, preventing any one organ's qi from becoming overactive and injuring the others. Additionally, in folk tradition, eating pears at Jingzhe is customary, as the weather is suddenly warm yet dry, and pears can moisten dryness, generate fluids, clear heat, and transform phlegm -- another seasonally attuned health practice.
From all this we can see that every detail of Jingzhe health cultivation -- rising early, walking, stretching, reducing sour and increasing sweet, eating pears -- is pervaded by a single principle: follow the heavenly seasons, maintain harmony with the qi of heaven and earth. The essence of health cultivation is not to "fight" aging with supplements, but to synchronize the rhythms of body and mind with the rhythms of heaven and earth. At Jingzhe, a time of surging yang qi and abundant vitality, to let body and mind also surge with vitality -- this is the highest art of nourishing life.
