In training Biu Jee we are taught to be free. The first forms tell us about normal situations. Biu Jee is for the abnormal situations. The ideas in Biu Jee sometimes will contradict normal Ving Tsun (Wing Chun) ideas in order to allow the person to survive in a bad situation. We are told to do what is necessary to survive and so there are no limitations. Styles have different concepts and objectives. With Ving Tsun (Wing Chun) we want to attack our opponent in a very direct and savage manner. Other styles will contradict this objective by attempting non-direct tactics. If we combine them our objectives can become confused in the heat of the fight. We will be less effective.
