Taijiquan's Comprehensive Rhymed Formula is a translation by my former instructor Dr. Xianhao Cheng whom I grew up with in Norfolk/Virginia Beach (now in Philadelphia) has an article out in July/aug issue of Kung fu magazine. It is a translation of a rare poem from Yang chen Fu that gives some guidance on practice and application. Grandmaster Jiang Yu Kueng received this during a time Yang chen fu and students lived and trained in Hangzhou China. Yang taiji is very strong there.
I suggest serious Yang taijiquan enthusiasts of all levels to have a look at this important article. Its poem is translated in english with chinese text as well at end of article. I would like to hear opinions.
