The korean vs chinese style
I practise kungfu and TKD for 8 years, frankly speaking the style really doesn't matters. In TKD, you have to be very fast to beat a WC guy at his game and likewise the WC guy has to know when to step in and not get his fingers snapped by a kick. In short as the chinese say:" shui pi shui qiao" - whoever is the faster ones win. Of course this is only half true, skill counts for the other half. Again the Wc guy must also know what stylr of TKD his opponent has, WTF or ITF? Likewise for the TKD guy needs to know what style of WC he is fighting with, both of them must change their gameplan to suit their opponent.
