I learned NEVER to bring up CMC while training with my Sifu, but then bringing up Tung Hu Ling just gives him happy memories and ideas which can be equally as painful
You may be interested to know that a disciple of a disciple of YCF was the official representative of that that branch of Yang style here in Taiwan -- Wang Zi-he. He was very secretive and no where near as popular as ZMQ but he was quite skilled. His opinion of ZMQ was apparently the same as Tung's. Li Ya-xuan, another disciple of YCF, shared that opinion. It seems that ZMQ perhaps wasn't all that popular with his shixiong.
But his method does work for some people.
