Well put, Joy.
WC/VT/WT is said to be a complete system. According to a traditional TCMA perspective, that would mean thet it addresses Ti, Da, Shuai, Na or kicking, hitting, throwing and locking. Not all equally of course, but nevertheless it does encompass all four combative aspects to some degree.
WC is built from seed techniques such as tan, bong, and fook, from which a nearly infinite number of solutions or applications may emerge as needed. IMO a good understanding of WC demands divergent thinking -- at least at the higher levels. Instead, some sifus and organizations encourage slavish conformity and cult like dogmatism. Or at least that's the impression some of their students give!
