Did you buy them in China? Maybe the french/US american fakes aren't even available in China, I guess they are rather a western problem. Because the really old chinese original company, Dafu Feiyue, from 1920, also started to use the red circle, as well as keeping the green triangle. The later subsidiary company of the chinese original, named Top One Feiyue, which is actually the one meant especially for martial arts use, only uses the green triangle. Well, and the french/american stolen fake company only uses the red circle, as far as I know, and also looks slightly different, as well as being much more overprized. 

Or in short: It's an absolute mess.
