Angelika Fritz , Taijiquan practitioner and Blogger at qialance has compiled a Taijiquan & Qi Gong Dictionary.
It is the result of a lot of research into terminology and meaning. It is, as she says, by no means a definitive work. Rather it is a work in progress. And isn't that just true of our own Tai Chi practise?
There are lots of terms I wasn't familiar with but I was delighted to find He Gu (Hu Kou) included. My late teacher John Kells taught that this was linked to the Root and was important in pushing hands.
It would be interesting if in a future edition there were also illustrations. All in all this is a nice little reference volume and I enjoyed reading through it.
It's available in the UK on Amazon - click here
