According to the basic theory of traditional Chinese medicine, "spleen and stomach" is the pivot of the whole body's qi, and in Tibetan images, the contents of lung and kidney also mention the importance of regulating the whole body's qi.

Lung governs qi, that is, lung governs the whole body qi, and the declaration and surrender of lung plays an important role in human qi-moving; Kidney stores qi. After the lung qi subsides, it is necessary to seal the kidney to keep breathing evenly.

In fact, all zang-fu organs have the function of regulating qi-flowing, such as dispersing the stagnation of liver, and the promotion of heart-qi to blood vessels is also very important. When you are familiar with traditional medicine in China, you will find that when you talk about the functions of all zang-fu organs, you will emphasize its importance. In fact, every viscera is very important, and there is really no need to prioritize. After all, all zang-fu organs are closely related, and a dirty disorder will cause his dirty disorder.

The qi of human viscera is divided into spleen ascending stomach descending, liver ascending lung descending, and heart and kidney intersecting, which is the interactive relationship between viscera and collapse. However, every viscera itself has the movement of qi, such as the interaction between qi and nourishing kidney yin and transpiration of kidney yang; Qi-qi interaction of convergence of liver-yin and hyperactivity of liver-yang; The lung is the interaction of declaration and descending. Promoting qi is the movement of qi, that is, ascending, descending, entering and leaving, dispersing and merging. As long as the human body is alive, there is gas everywhere.

The above is my understanding, which is scattered and disorganized. I hope they can help you.
