The health care of pharynx and body fluids is very simple. Clean up after getting up in the morning and empty the urine. Facing the air circulation places, spring, summer, autumn and winter correspond to the east, south, west and north directions respectively. Feet shoulder-width apart, palms overlapping on navel. Relax and breathe with your abdomen. When you have made enough preparations, you can start stirring your mouth with your tongue. The tongue should stick out of your teeth, but on your lips. The tongue is stirred up and down around the teeth first, then left and right, 36 times each time. When stirring, use gentle force. When the body fluid is full, wash your cheeks 36 times, and then swallow them in three sips. After a period of time, rub your navel three times clockwise and counterclockwise.
The above actions can be done 1-2 times a day, and repeated 3 times each time. This set of movements can be done in the morning, at noon and before going to bed at night. Long-term persistence can "moisten the five internal organs and delight the skin". After saliva is produced from the oral wall, it passes through the root of the tongue, throat and lungs to the liver, enters the renal canal, is stored in the abdomen, and then is transformed into Jinhuandan, forming essence. This process can strengthen the spleen and stomach, moisten the skin of the five internal organs, and invigorate the kidney and brain. The human body has its own medicine. Saliva is a "self-help pharmacy" in our body. It is cheap, simple and effective. As long as you swallow saliva one day earlier, you will be healthy one day earlier.
This method is the easiest way to keep healthy. As long as you persist for a long time, it will be beneficial.
