Except that video wasn't a Tuisho competition, it was a friendly roll between two grapplers.
.
Except no one ever said it was a tuishou competition and no one ever said it was BJJ or a grappling meet up either, they did however label it "Marcelo Garcia and Tuishou Chen Do Karate-do". It was a friendly meet up between to Martial arts practitioners., I am sorry and saddened that you cannot see that
Again, if Tuisho isn't a complete grappling system then my apologies for thinking it was.
Well we have established, multiple times now, based on your posts, that you have no idea what Tuishou is.
For example;
1) it is not a system, it is part of multiple systems that use differently based on that system and basically it is used as a two-person training system within those systems for various reasons and applications
2) did you even bother to read, with an unbiased eye, the post I made giving a general explanation that there are different types of Tuishou and the one the person in the video does is "Competition".
My guess is you didn't, you won't and likely do not care to. So I have said all I can say to you on the subject, you obviously have strong , albeit incorrect, views of all things that are not called "Grappling" so any further discussion with you on this topic would be a complete waste of my time.
