Here are just a few of the many internal connections that are within the wu chi posture of Sun style hsing yi chuan. As far as I know the connections appearing on my blog are not posted anywhere including the Sun style hsing i book. These connections are essential for developing wholebody power. Please work with them to see what you come up with. The clinic is slow right now so there will be time to write more connections for the taichi and santi postures.
In the interest of time I will give just a few for each of the 6 directions. You will notice these are yin/yang pairs:
Up: Bai Hui, tip of tongue to roof of mouth
Down: sacrum, shoulders
Forward: tip of thumbs
Backward: Mingmen (kidney region)
Side to side: scapula, heels split the earth
At all times relax the ren channel as the du channel has the intention of going upward.
If you have any questions please write.
