Lee's Latest Translation Effort

I recently finished a translation of the 7th Treatise on Jin and Physics from Professor Cheng's 13 Treatises.

This translation spawned a lot of additional work as I tried to understand the cultural context in which Cheng wrote this treatise. I’ll share my results shortly in another piece.

But, for now, you can peruse Cheng’s ideas about the mechanics behind Tai Chi Chuan.

You can find all my translations on the Translations page.

The Yang Family Eight Word Formula, freshly translated into Spanish thanks to J Félix Fernández.


We base our work at Rocky Mountain Tai Chi on the "practice tripod" defined by Professor Cheng: form, push hands, and sword.

We also incorporate practice of various qigong sets, fundamental drills, standing meditation, and internal work.

On Friday mornings, we work with cancer patients at the Cancer Center at Boulder Community Hospital. It's a great opportunity for us to help people by sharing the art and its benefits.  This class is open to anyone dealing with cancer treatment whether at BCH or other facilities. Click here to see the BCH flyer.
