Knocking teeth: after waking up in the morning, don't talk about being alive, calm your mind, get rid of other thoughts, relax your whole body, close your lips and unite your mind, and then make your upper and lower teeth beat each other rhythmically, clanging and sounding for unlimited times. When you start exercising, you can pat it about 20 times. With the continuous progress of sports, you can gradually increase the number and intensity of knocking teeth, generally 36 times is better. Strength can be measured according to the health of teeth. This is to complete a knock.

Swallowing body fluid: From the point of view of Chinese medicine, after percussion, it should be supplemented with "Red Dragon Stirring Tianchi Lake", that is, after percussion, stir the upper and lower gums and tooth surfaces with your tongue in the cavity, with gentle and natural force, first up and then down, first inside and then outside, and stir for 36 times, which can massage the gums, improve local blood circulation and accelerate the nutritional blood supply of the gums. When you feel that body fluids (saliva) are produced, don't swallow them and continue to stir. When saliva gradually increases, put your tongue on the palate to gather saliva, rinse your cheeks with saliva several times, and finally swallow it slowly in three times.

Extended data:

In the process of chewing teeth, oral saliva increases. Chinese medicine believes that saliva can nourish the five internal organs. Modern medical research has proved that saliva contains many substances related to life activities.

Health experts call saliva "golden jade liquid", which, like jingxie, is the material basis of life. Huangdi Neijing said: "Spleen belongs to Tianjin, and kidney belongs to Tianjin". Saliva is closely related to spleen and kidney, which plays an inestimable role in human health and longevity. Li Shizhen believes that saliva has important functions such as promoting digestion and absorption, irrigating internal organs, nourishing yin and reducing fire, promoting fluid production and tonifying kidney, moistening skin and hair, and smoothing joints and orifices. "Red Furnace Divides Snow" points out:

"body fluid is swallowed, blood is turned into painstaking efforts, eyesight is improved in the liver, spirit is nourished in the spleen, qi is helped in the lungs, and birth is refined in the kidney, so naturally all diseases are smooth."
