The 1st section is primarily about Lat sau jik Chung ("springy forward force", that constant desire for the hands to attack when free of, obstruction. the hallmark of effective wing chun combat). but there is,
much more than just that one concept being examined. it is the very structures that are involved in that. and in footwork, kicking, simultaneous, attack & defence, power generation and a host of others, hence my, definition - structure.
the 2nd section concerns the various ways in which we, might understand the concepts/techniques/strategies required of overcoming situations where we have lost, control of the centreline( jung sam), and are unable to face, our adversary, in short it provides ways of being able, to face our opponent when placed in a compromised position such as arm-locks, bear hugs or grappling situations. hence my definition - recovery.
Finally, the 3rd section shows us various combinations of, movments applied with one hand, to emphasise the importance of realising that we are capable of using one hand for more then one motion at a time. in other words, just because i have just used my left hand to attack or defend does not presuppose that it cannot be used again immediatlely, rather then relying upon the other hand first in atypical " one - two" action. in addition, it helps us to add flow to our actions, to develop natural motions that move easily from point to point. it is important to note at no time is this section suggesting that, the combinations utilised MUST be done in exactly those,sequences. they are merely linked together for ease of practise and improvement, NOT as set motions. Therefore the main aim of the 3rd section is the development of one of the key attributes for combat success - coordination.
