The Gray Dragon is based on earth element.
You need to practice Karate and Muway thai to understand and perfect it.
There is also the iron style in southern Shaolin, Hungar, and Wing Chun are based in earth element.
The Gray Dragon is the origine of all earth element styles.
In animals there is the ram and the ibex, the origine of Karate, and the famous O tsuki, like a rok falling down from a mountain.
The elephant is one of the basis of Muway thai.
Gray Dragon is the combination and the origine of all of it.
In my years of hard training i get the knowledge of the Dragons arts with details in theory and practice.
This technique is the Hammer Fist, just few movements.
