The basic understanding of Brown (A combination of the Wooden Dummy and the Biu Tze hand form); we give a breakdown as with Muk Yan Jong and Biu Tze or Brown Level Grades of the form into bit size pieces for the student to gain a good understanding of the techniques the applications for each section of the form.
This is the first few sections of the Muk Yan Jong which develops turning stance, moving elbow energy understanding of the changing centerline, and induces the concept of waist energy (Yiu Ma)along with some basic form to open hand applications and methods along with open hand drills, section drill on the Jong, Chi Sau and free applications .
Brown 2 level
This is the first section of the Biu Tze which teaches how to use your elbow techniques and recover the centerline also to cover angles, use and release the two way energy that is trained with the Yiu Ma as well and the open handed applications and the chi sau method to free flow.
Brown 3 Level
This is the complete Muk Yan Jong form, which allows the free flowing movement of techniques, open handed drills, set dummy drills, chi sau drills and free applications.
Brown 4 Level
This level is a compleate understanding of the Biu Tze hand form along with all the drills and chi sau applications and the open hand methods applied into a full contact sparring session with two opponents.
As a student develops within the advanced levels of the Wing Chun / Ving Tsun system and develop the necessary ability to control which is required to manipulate a situation and the mobility that comes from training on the Muk Yan Jog this then becomes the new skill set. Many people misunderstand the emphasis on this form and consider it just turning or hitting hard, however it give you a solid foundation and the ability to train your angles, direction of attack, and to understand the ability to track your opponent with hands and kicks.
With each section of this form a specific understanding of the fundamental principles of changing the centerline that make this the form a totally mobile fighter needs to apply.
Without the development of the first form you would not be able to understand the use and co-ordination required in the turning stance (Yiu Ma), and the generation of power combining the use of arms hips and waist, while correct understanding of your Centerline (Chung Sin) is fundamental you also have to know how and when to change it and to apply this new two way energy and balance.
