Most martial artists look good in their polished videos, but the question is- can their techniques work in real life? Tu's techniques will not work with an opponent who varies his punches after establishing the jab. Also said opponent will have success by the continued use of feints along with footwork, like sidestepping. Tu would be good in martial arts films, because the choreography involves rhythm. But a real fight does not look pretty or have rhythm. Therefore, Tu's kung fu would be broken in a real combat because he is "crammed and distorted by classical mess."
