Function and function of opening the bow left and right like shooting an eagle: The formula of "opening the bow left and right like shooting an eagle" in Baduanjin enhances the stretching of our lungs, shoulders, hands and ankles and the exercise of lower limb muscles. The most obvious thing is "opening the bow", with both hands pulling with opposite force, sitting down, and finally bowing to exhale. But when the password is "synchronized", the breathing state converges.

It should be noted that breathing and sucking are generally coordinated with the rise and fall of the body, and breathing is generally up and down. Only in this way can we achieve the goal of internal adjustment and good practice. It is the key to health qigong to practice Baduanjin and feel the corresponding movements of breathing and sucking.

It is said that "opening a bow from left to right is like shooting a sculpture", which can express the anger in the chest during the process of expanding shoulders and chest. The "eight-character palm" in exercise can effectively stimulate points such as Taiyuan and Shangyang during exercise, so as to achieve the purpose of dredging the lung meridian and dredging the lung meridian. Stimulating Du Meridian and Shu points on the back and regulating the qi of Taiyin Meridian on the back of hand can eliminate shoulder and back pain.

During training, the mind is "eight-shaped, and the toes grasp the ground". When opening the bow to the left, the right foot is relaxed, and when opening the bow to the right, the left foot is relaxed. Repeated training can lengthen the hands and ankles. In the whole process of stretching tendons, the qi and blood of meridians can be circulated. From this point of view, stretching tendons is one of the ways to delay the aging of bones and muscles and keep healthy.
