Zhu Tan (Various Phlegm Disorders) refers to conditions caused by the obstruction of blood vessels, where accumulated water from drinking fails to dissipate, thus forming phlegm. The manifestations may be cold or hot, solidified or due to undigested food, accompanied by epigastric and abdominal fullness and stuffiness, shortness of breath, and excessive sleepiness. Since the symptoms are diverse, it is termed "Zhu Tan."

Liu Yin (Flowing Fluid Retention) occurs when excessive water intake leads to fluid moving between the intestines and stomach, producing gurgling sounds. When Qi and Blood become stagnant and meridians fail to circulate freely, water cannot be distributed smoothly, stagnating and overflowing into the region of the Bladder, causing shortness of breath. Improper care involving exposure to cold can also lead to deficient abdominal distension. If not cured for a long time, it may condense into a mass known as Pi Ji (accumulation).

Liu Yin with Su Shi (Flowing Fluid Retention with Retained Food) results from excessive water intake, where water Qi flows between the Spleen and Stomach. The Spleen, affected by dampness, loses its ability to digest food, leading to belching with the odor of retained food, abdominal distension, high fever, or acid regurgitation, all of which are characteristic symptoms.

Liu Yin (Stagnant Fluid Retention) arises when one drinks excessively after consuming alcohol. Water Qi stagnates in the chest and diaphragm without dispersing, causing pain under the ribs, shortness of breath, and thirst, which are typical signs.

Liu Yin with Su Shi (Stagnant Fluid Retention with Retained Food) occurs when excessive water intake follows alcohol consumption. Water Qi stays between the Spleen and Stomach; the Spleen, burdened by dampness, cannot digest food, resulting in belching with a sour and foul odor, abdominal distension, and acid regurgitation, hence the name.

This condition involves excessive water intake causing water Qi to stagnate between the two hypochondriac regions. When combined with cold pathogenic factors, it condenses into a lump, termed Pi Yin (Accumulated Fluid). Located under the ribs, it presents as a taut, transverse elevation that produces a splashing sound upon palpation.

Zhu Yin (Various Fluid Retentions) are generally caused by the stagnation of Ying Wei (Nutritive and Defensive Qi), dysfunction of the San Jiao (Triple Burner), and excessive water intake leading to accumulation and formation of Tan Yin (Phlegm-Fluid). Manifestations include distension in both hypochondria, mental restlessness and oppression in the chest and heart, blurred vision and dry mouth, vomiting, counterflow Qi, and shortness of breath. Due to the variety of symptoms, it is called "Zhu Yin." Treatments such as herbal decoctions, external heat application, acupuncture, and stone therapy have specific formulas. Methods for nourishment, supplementation, and Daoyin (guiding and pulling) exercises are appended below.

The *Yangsheng Fang · Daoyin Fa* (Prescriptions for Health Preservation · Guiding and Pulling Methods) states: Lie on your left side, then on your right side, close your eyes, and hold your breath twelve times to treat persistent fluid retention. If fluid pathology exists on the right, hold the breath and direct the expulsion downward to resolve it.

It further states: To circulate Qi, bow your head and lean against a wall, holding your breath twelve times while using your mind's intention to guide the expulsion. Phlegm-fluid and retained food will exit from the lower part, leading to spontaneous recovery. The method of circulating Qi involves keeping the body straight and bending the neck, allowing Qi to descend; one cycle cures retained food. Long-term practice allows natural expulsion without needing to block the nostrils.
