Here is an example where Grandmaster Wong responds spontaneously to an unexpected attack

Sun Tzu's advice that "Defeat is what you hand to your opponent, victory is what you secure yourself", though little understood by others, is very useful to us. It is because today's fighting situations are such that if you ensure your own safety first, particularly by not handing out your disadvantages to your opponents, it is not easy for your opponents to defeat you. This was quite different in the past when combatants were so well-trained that they did not give out any disadvantages to their opponents, in which case one had to create means to secure victory.

Reversely, in today's sparring situations, combatants frequently give out free-offers, but most of the times their opponents do not realize it, and when they realize they are not sufficient prepared to exploit the free offers. Hence, if you realize the free-offers your opponent unknowingly hand out and have trained yourselves adequately to exploit them, you can often defeat your opponents without having to create means to secure victory.

Grandmaster Wong emphasizes not exposing yourselves, and conversely covering your opponents adequately. There are also a few rare impromptu occasions where Grandmaster Wong responds spontaneously to Sifu Jamie's tricky, surprised attacks and where he applies some marvelous techniques to overcome seemingly hopeless situations.
