Here are two short You Tubes of Dr. Pang teaching La Chi and Chen Chi I thought you might enjoy.
In this teaching video, Dr, pang explains the details of Chen Chi:
1. arms in 25 degree and straight; fingers extended, finger tips moving up while shoulders joints thrust up and base of the palms pushes down in the open and down movement;
2. Shoulder joints moving both back and up slightly;
3. Eventually torso's chi is activated and move up from the dantian to up body when you practice long enough.
Enjoy, Mingtong.
In this video, Dr. Pang guides and explains Lachi as a direct way to work with chi for healing. The key is to move slowly and relaxed manner so you can feel more chi. You can recieve his energy transmission in this intro teaching. More detailed teaching will be covered in the next Adancing workshops on Jan. 28-29.
