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.
