Wind, Thunder, Grain, Rain, River, Sea, Heaven, True Qi: How the Nine Qi Enter Zang-Fu Networks

The earlier Eight She introduced the Nine Qi: Qian, Gui, Cang, Sheng, Dong, Zhang, Yu, Zhi, and Zhuang. In “Tongtian,” several of these qi-transformational stages are connected with natural images and zang-fu.

The text says in sequence:

Wind qi connects with the Liver and generates.

Thunder qi connects with the Heart and moves.

Grain qi connects with the Spleen and grows.

Heavenly qi connects with the Lung and returns.

Rain qi connects with the Kidney and nurtures.

River qi connects with the Brain and stops.

Sea qi connects with the Stomach and is Zhuang.

True qi connects with Sanjiao and is Qian.

The most important feature here is not forcing each natural phenomenon into one organ, but observing the verbs that follow each pairing.

Generate, move, grow, return, nurture, stop, Zhuang, and Qian form a process chain

Wind–Liver corresponds with “generate,” Thunder–Heart with “move,” Grain–Spleen with “grow,” Rain–Kidney with “nurture.” These are clearly not organ names but different stages of living process.

The Lung’s “return” concerns inhaled clear qi; Sanjiao’s “Qian” is placed at the root position of true qi and whole-body qi transformation; the Brain’s “stop” concerns qi dispersing into form and the governance of entry and exit; the Stomach’s “Zhuang” is linked with the Sea of Water and Grain and with the sinews.

This set of pairings can therefore be understood as follows: different zang-fu networks undertake different types of qi-transformational task.

Zang-fu are not isolated boxes

“Tongtian (IV)” further unfolds each pairing. When wind qi connects with the Liver, for example, the passage also involves fluids, Defense, Hand Yangming, and Foot Jueyin. When thunder qi connects with the Heart, it also involves the Lung, gathering qi, and clear-turbid entry and exit. When grain qi connects with the Spleen, it also involves Sanjiao and Nourishing-Defense qi.

“Wind connects with the Liver” therefore cannot mean “wind belongs only to the Liver.” It is an entry marker that immediately expands into a network spanning channels, fu, fluids, and blood.

Why use wind, thunder, grain, rain, river, and sea?

Within the text’s own language, these natural images are not decoration. Wind exhibits rapid movement; rain moistens and irrigates; rivers flow and gather; the sea is where many currents converge. The author uses visible natural processes to express internal qi-transformational patterns that are difficult to observe directly.

But the distinction still matters: this is a classical modeling language. It does not mean that “thunder,” for example, can be directly equated with a modern electrophysiological indicator.

The next article shows how “Tongtian” gathers these networks into a series of “seas,” revealing whole-body exchange centers.
