The growth of the ribs is regular. At the beginning of the life, infants are soft because their tendons and tendons are very soft, and the soft tendons and tendons can smooth the channels and collaterals and make qi and blood full, thus showing vitality. With age, the tendons begin to contract and the limbs gradually become stiffer. Slight contraction of muscles is characterized by stepping down and lifting the thigh to a horizontal position; excessive muscle contraction can cause neck tightness pain, waist stiffness pain, incapability of bending down, back tightness pain, leg pain and paralysis, incapability of squatting, radioactive traction pain of tendons of long and short feet and heels, tightening sensation of hip joint ligaments, incapability of lifting and stretching thighs, inflexibility of turning, muscular atrophy, incapability of stretching and bending hands (shortening tendons of hands), and expansion, numbness and pain of hands, feet, elbows and knees, unsmooth movement and the like. In the past, the tendon contraction mostly occurs in the elderly, but in recent decades, the life style of people is greatly changed by scientific products such as televisions, computers and the like, and shoulder and neck diseases and tendon contraction are common in children and middle-aged and young people. Even among people who love sports, the symptoms of cramping are not very boring. Due to the lack of warm-up and stretching exercises prior to exercise. And the body parts of many sports activities such as golf, tennis and the like are relatively limited, and the water temperature is too low when swimming, which can cause muscle contraction. Stretching the tendons not only can prevent and treat the contracted tendons, but also is a 'life regression' exercise, i.e. returning to the infant stage without returning to nature.
