(pull the bow left and right like a shooting vulture)

The first pose is to raise your hands to support the triple burner of heavenly principles, which generates the yang energy of the body and clears the triple burner meridian, the main artery of the human body. The Sanjiao meridian is the Hand Shaoyang meridian. According to the order of the twelve main meridians , the next movement is naturally the movement of the Hand Yangming meridian. The Hand Yangming meridian is the Hand Yangming large intestine meridian .

The large intestine and the lungs are the exterior and interior of each other, so the large intestine meridian of Hand Yangming is naturally the same as The lung meridian of Hand Taiyin is the exterior and interior. The origins of the large intestine meridian of Yangming in the hand and the lung meridian of Taiyin in the hand are at the index finger and thumb respectively. Therefore, the natural corresponding action is "drawing the bow left and right like a shooting vulture". Therefore, the thumb and index finger should be kept straight during practice, thus mobilizing the two main meridians.

There are also those who use the thumb and index finger to make pistol-style movements. In fact, the shape of the movement does not matter, as long as the two main fingers can be mobilized.

After practicing the Hand Yangming Sutra in the proper order, the next step should be to practice the Foot Yangming Sutra, so the next step is the movements of Baduanjin , which is a matter of course. This sequence of the Twelve Classics is the main exercise sequence logic of Baduanjin, but there are three exceptions.
(The Twelve Classics are divided into six yangs and yin, yang is the exterior and yin is the interior. Every movement of Baduanjin takes into account both exterior and interior.)
