Because there are many styles of Bagua Zhang (Eight Trigram Palms) each has their own particular palm shape that depicts their own unique style. For example it is said that some Yin Bagua Zhang practitioners use the “Ox Tongue Palm” (Niu She Zhang) while other styles use the “Willow Leaf Palm” (Liu Ye Zhang). But the Sun style Bagua Zhang practitioners use the “Dragon’s Claw Palm” (Long Zhua Zhang)) this particular palm shape is like the both hands are about to catch a ball in each hand, the centre of the palm is hollowed, while the fingers are separated and curved at each joint.
The Tigers mouth ( Hu Kou) which is the gap between the index and thumb is held open and rounded. This gently stretches the palm allowing for the qi to flow smoothly into the fingers and palms. By allowing the fingers to be separated and slightly curved forwards means that the centre of the palm can become hollow, which lets the qi gather into the centre of each palm, activating the energy point (Qixue) which is located in the centre of each palm and is called the “Laogong” which is on the Pericardium Meridian or also known as the Heart protector.
While the Sun Style Bagua Zhang practitioner begins to walk the circle they will hold the Dragon’s Claw Palm shape with both hands.The sensation that each individual should feel in their both hands as they perform the circle walking exercise is a build up of warmth or heat in the Laogong points located in the centre of each palm, this warmth will then spread to the fingers allowing for the both hands to have the feeling of fullness or thickness which means the both palms are full of qi.
In general the Sun Style Bagua Zhang is known as the “Dragon Style” even thou it involves the practice of another seven animal shapes such as the Bear, Sparrow Hawk and Lion for example. Over-al it’s style and flavour is that of the Dragon shape, hence why Sun Lutang himself called the posture the “Green Dragon Turns Its Body ” ( Qing Long Zhuan Shen).
