Shen Qiang can often press Yao Yan point, which is located in the depression of 3 ~ 4 inches on the left and right of the spinous process of the third vertebra on the back. Traditional Chinese medicine believes that regular massage of waist and eye acupoints can warm the kidney, strengthen yang, unblock qi and blood, and enhance the qi-receiving function of the kidney, thus achieving the effects of prolonging life and strengthening the body. The specific method is as follows: 1. After heating your hands, press the Yaoyan point tightly, pause for a moment, and then rub it down to the tail (Changqiang point). Then go back and rub it again, 50 ~ 100 times each time, and eat it once in the morning and evening. 2. Make a fist lightly with both hands and massage with your eyes or back of your fist for about 5 minutes each time. 3. Make a fist with both hands, tap the waist and eyes, or hold the waist with both hands for 3 ~ 5 minutes each time. Taoist health theory holds that rubbing the waist and eyes with the palm can not only warm the meridians and moisten the eyes, dredge the meridians and strengthen the waist muscles, but also play the role of hearing and eyesight, strengthening the kidney and prolonging life. This method is also helpful to prevent and treat diseases such as nocturnal emission, premature ejaculation, dysmenorrhea and menstrual disorders.
