"Grip solid" is a common hand style of Taoist health, and Ge Hong, a famous scholar of the Jin Dynasty, advocated "holding and holding one" in "Holding Puzi".
The specific method is to clasp the thumb in the palm of the hand, the fingertip is located at the base of the ring finger, and then bend the remaining four fingers, with a little force, and hold the thumb firmly as if it were a baby.
The ancients believed that holding it would help to calm the soul and calm the mind, collect essence, spread qi and blood, ward off evil spirits and prevent diseases.
"Percussion" refers to the incisors facing each other and gently tapping up and down rhythmically. Ancient health practitioners used percussion as a wonderful method to prolong life, and percussion was performed 49 times a day in the morning and evening.
Traditional Chinese medicine believes that the tooth is not only the bone, but also the kidney is the main bone and the marrow, so percussion can stimulate and protect the kidney qi, improve the body's immunity, and strengthen the life function.
"Pharyngeal Jin" refers to using the tongue to stir repeatedly in the mouth for many times until the mouth is full of jin liquid, and then rinse it repeatedly in the mouth, and when you feel that the saliva is sweet, you will slowly swallow the jin liquid, which can play a great role in tonifying the kidney yin.
