Do you *think* it might be *plausible* that there have been spies who brought training secrets back to their own militaries? Perhaps hundreds or thousands of years ago?

I'm sorry, the whole lineage thing just leaves me dry (with all due respect to Xue and others like him).
When you fight or spar someone, do you take notice of their strengths and weaknesses? their approach to offense and defense? their strategy? Has this ever changed your approach to either the same individual or others? Don't you think you might not be the first person to do so?
I don't see the necessity of bashing arts, beliefs, oral history, persons sharing these things herein, if we can all just accept that the most likely result is almost definitely what did happen.
