Hello my name is Douwe Geluk and i also practise and teach several Chinese martial arts. I have practised How Chuen Monkey Kungfu 'standing tall monkey martial art' which is based on the sasquatch, bigfoot or yeti a mythical creature.
But also Ng Ying Kungfu and Tai Chi Chuan and Chi Kung. Within Sasquatch Kungfu as Tai Chi and Chi Kung the Chi was, is an important factor. Chi does not have to be magical it can be the bloodflow, body heat and so on.
The bases lies in the fact that when you know certain forms or moves and the 'order' is absolutely no problem anymore you can feel them more and channel the chi by focus.
