The Lung governs Qi. If the deficiency and excess of Lung Qi are unbalanced, or if it is suddenly attacked by Wind pathogen, the functional activities of the Zang-Fu organs will be impaired, the meridians and collaterals will become obstructed and stagnant, and the Qi mechanism will fail to circulate smoothly and harmoniously, resulting in sudden upward reversal of Qi (Su Shangqi). Furthermore, due to anger, Qi may suddenly reverse and ascend; in severe cases, this can change into vomiting blood, injuring both Qi and Blood. For treatments involving decoctions, hot compresses, acupuncture, and stone therapy, there are separate specific formulas. Methods for tonification, nourishment, and Daoyin (guiding and pulling) are appended hereafter.

The *Yangsheng Fang · Daoyin Fa* states: Cross both hands under the chin, stretch to the utmost extent, to replenish healthy Qi; treat sudden Qi reversal with cough.
By crossing both hands under the chin, grasping the pulses at both sides of the mandible, bending the chin towards the intersection, and pulling tightly against the laryngeal bone, perform this stretching three times to the utmost extent. This replenishes sufficient healthy Qi, treats sudden Qi reversal and upward rushing Qi, drains diseases of the throat, regulates the breath to be long and even, and makes the voice resonant and bright.

The Lung governs Qi. When pathogens invade the Lung, the Lung becomes distended. Distension leads to obstruction of the lung passages. Obstruction of the lung passages causes stagnation of the airway, thus causing Qi to rush upward with panting and wheezing, making breathing noisy and obstructed.
Palpating the Lung pulse, if it is slippery and extreme, indicates Ben Tun (running piglet) type upward rushing Qi. If the pulse extends to the Yuji (LU10) area, it indicates panting. A slippery pulse indicates survival, while a rapid/forceful pulse indicates death.

Lung disease causes people to experience upward rushing Qi, accompanied by phlegm-fullness in the chest and diaphragm, stagnation of Qi movement, irregular panting, leading to sounds in the throat like the croaking of water chickens.

Qi and Blood circulate through the meridians, completing cycles repeatedly, all following regular patterns. The Lung is the upper cover of the five Zang organs and governs the circulation of Qi among the Zang-Fu organs. If the Lung is affected by pathogens, the airway becomes obstructed; if the airway is obstructed, the Qi of all other organs becomes stagnant; thus losing its regularity, causing Qi to rush urgently upward.

The so-called Ben Tun Qi is an accumulation of Qi in the Kidney. It arises from fright and worry/thought. Fright injures the Shen (Spirit), as the Heart houses the Shen. Worry and excessive thought injure the Zhi (Will), as the Kidney houses the Zhi. When Shen and Zhi are injured and disturbed, Qi accumulates in the Kidney, and the Qi moves up and down like a running piglet, hence the name Ben Tun. When this Qi attacks the Heart, one feels palpitations in the heart, as if startled by events or terrified by others, with the five Zang organs becoming unstable and erratic, vomiting immediately after eating or drinking, fullness of Qi in the chest, madness and dementia with instability, delirious speech, and hallucinations. These are the manifestations of Ben Tun caused by fright. If Qi fills and supports the heart/chest, causing oppression and confusion below the heart, aversion to hearing human voices, with episodes occurring at intervals, alternating between remission and exacerbation, shortness of breath upon inhalation, coldness of the hands and feet, internal irritability and knotted pain, and nausea with desire to vomit, these are the manifestations of Ben Tun caused by worry/thought.
Palpating the pulse, if it comes feeling "Chu Zhu Chu Zhu" (a specific pulsation description), it indicates Ben Tun disease. If the Kidney pulse is slightly urgent, sinking and cold/extremities, accompanied by Ben Tun, the feet cannot hold the body, and urination and defecation are obstructed.
