I insist they are not pure authentic chinese martial arts. Chinese and Thais are different tribes from the beginning. Even now there is a small group of Thai people in Southern China living a completely different lifestyle(speaking Thai also). The reasons some Chinese said MT should be influenced by Chinese was the old history books saying that Thais moved down from Altai in China, but after the discovery of ancient Thais grave in the present time Thailand, the old books are now obsolete. Chinese striking martial arts originated from Taoism and later Shaolin(Mahayan sect) school, the grabs and throws are influenced by Persians(now Iran)and Mongols and very little resemble MT. MT originated in Siam down south and influenced by Hindu and Buddhism(Lankan Hinayan sect) cultures. If you put Thai swords and stick(Krabi Krabong) in MT fighters'hands they can apply their MT skills to fight with weapons easily because they came together in the first place. But if you put Chinese narrow swords or the Tao swords in these new breeds of Chinese fighters you will see the conflicts. "KhunYak Pha Nang"(which is not a throw) is still different from "grasping the jade belt" just as "Breaking the great elephant's trunk(not tusk)" is from "Standing on Mt.Tai" in both how and why to execute. How to move forward or backward, how to stand guard, all are different, especially the concept of defence from the humbleness of Thais. Chinese are arrogant and will never accept truths easily, that's why they even change the meanings of Nirvana of buddhism into a kind of heaven full of worldly hapiness.
