Even though it is advertised by U.S. entities, it's has heavy envolvement and endorsement by china mainland apparently. In doing research, it's pretty much the same gov. that in the late 1940's and 1950's that persecuted, killed, and destroyed much of the martial arts teachers, religous centers, temples, etc... and now they are doing an about face and doing the world tai chi & qigong day. I was actually told specific stories of what happened in China as well when I enquired about TTCS participating in this day (why not right?) but in learning about more of the history I fully understand why many martial arts/religious instructors from China durring those time periods don't participate in this day BUT the concept of the day is a good one which is why TTCS does an awareness day.
Now I do have to say that even though I have been a member for 12 years, I'm not a spokes person for the TTCS, but these words apparently came from Mr. Moy's own mouth along w/ stories of his own experience walking along w/ a fellow student one day and the gov. shooting them w/ morter shells... his friend died in front of him.
