I'd like to say a few words about my favorite system - vietnamese wing chun or vinh xuan in vietnamese.
First of all every body welcome to visit our web site
http://vietnamwingchun.com/en and especialy its video section
http://vietnamwingchun.com/en/video.html.
I was asked about the differences between our lineage and the very popular Ip Mans lineage. Actually it is very difficult question because the systems are very very different. It starts from the forms (tao or quen or kata whatever you call it). In our system we have the Sim Lim Tao form ( but the movements and way of is doing different), 108 movements, it is very practical form , one praise it in few ways : with wooden dummy , with partner without steps and with partners with different steps. Also we have 5 animals system that contains 6 forms , and it is unique for our style. It have a lot of application in the training process , it builds ability to move with all the body in harmony,also it teaches 5 different tactic principles in the fight . Also the balance it is very important issue in our system we have a lot of exercises develops the ability to keep the balance in all situation and to take the opponent of the balance as well.We have Chi kung form in our system to ddevelop the inner power. But the main difference to me it is the power generation , as far as i know in Ip Mans system they generate the power from the "elbow force" , in our system we generating power from the legs its similar to Tai Chi in some way.
That were the differences as i see them , of course it in a nutshell .And i'll be glad to answer to all the questions about the system.
