This is the foundation form of the Chen Shi Hunyuan Xin Yi System created by the late Grandmaster Feng Zhiqiang.
It is designed for beginners and older people, with the emphasis on moving the energy round the body in circles.
Grandmaster Feng designed the system from his many years of research and he meant the system to be a straight line to gaining health using his methods.
The hands in Hunyuan taiji are the guide and whatever way they circle is mirrored in the Dantian this gives the practitioner a direct link with intent as he can feel which way the hands move and so transmit that to thinking about moving the energy in the Dantian.
I had previously practiced Sun Style Taiji for over 12 years but felt it needed the Xing Yi to gain the benefits. My short experience with Hunyuan has given me better results regarding health in a much shorter time. I have gone on to learn the 38 step cannon fist form as well, giving me a more rounded training as I have a form from Yi Lu and one from Er Lu.
When I am next in Beijing I am hoping to learn the 48 step Hunyuan Taiji and progress more in the system. My teacher Chen Hui Ying is a great teacher, patient and knowledgeable plus he can use the taiji if he needs to and I am lucky that he shows me the martial as well as the health.
