POST 317 14OCT 2017

In this POST 317  we invite you to consider the execution in opposite side of the previous exercise in POST 315

Exploring this alternative will provide you another exciting dimension in the  development of your personal growth through the practice of martial art exercises.   

Thank you for your attention and efforts.

A special thank to Paola Binh Lam.








Phép Hoán-nh.
This term means method for permutating and changing images and movements in a quyen (quyen = form, choreographed movements). We call it ‘Change’  (for the Way of Change).


The basic version of a quyen when students first learn it is called ‘the main version’. From this main version, an advanced  learner will be asked to perform a more sophisticate version of the same quyen by executing Hoán-nh ‘Changes’. There are methods and rules to be taught, here it is.
The easiest rule of ‘change’ consists of executing exactly the same movements but simply at the opposite direction. For example if the quyen starts ‘facing South’ then at the end the performer will rotate 180 degrees to restart with the same movements but now ‘facing North’.
At more difficult levels, it will be executed under the rules of Symmetry.
Symmetry means that one shape becomes exactly like another if you move it in some way: turn, flip or slide.
There are three basic types of symmetry: mirror symmetry, rotational symmetry, and point symmetry.

Mirror symmetry occurs when your image (meaning a position in your quyen) is reflected like looking in a mirror.
To execute ‘mirror change’ you will replace the original movements –steps, legs, arms, direction and so on- by the corresponding images as you could see them in a mirror.
This is what we apply almost to any of our quyen. At first level students learn the main version; then at advanced level students will learn the ‘mirror change version’. We call it by ‘doing the opposite’  which means executing the ‘mirror change version’ after the end of the main version.

Description: C:\Users\Anne\Documents\_WORKING 2017\KY LO 2017 March working\KY LO part 5 SYMMETRY\Rotational symmetry 170414.jpg-Rotational symmetry
Rotational symmetry occurs when your image is rotated around a central point.
The image can be rotated more than once, and it stays like the same original image (because it is not a mirror image) but put at a different point on a rotation curve. 
This method is often used in the study of fighting  techniques where there is a need of changing position while keeping the same elements (legs, arms, fists) as in the original image.

Description: C:\Users\Anne\Documents\_WORKING 2017\KY LO 2017 March working\KY LO part 5 SYMMETRY\POINT SYMMETRY 170414.jpg-Point symmetry
Point symmetry occurs when every part has a matching part across the central point (same distance but in the opposite direction).
This method helps in having an opposite image without the mirror effect; the body, the legs, and the arms stay the same but in the opposite position across the central point.

Description: C:\Users\Anne\Documents\_WORKING 2017\KY LO 2017 March working\KY LO part 5 SYMMETRY\MIX ASYMMETRY POINT SYMMETRY 170415.jpg-Mix-methods
Certainly the above methods of symmetry provide solid foundation to execute many ‘change’  however they could never satisfy all the needs since most of our quyen can be performed on 4 directions, and sometimes on 8 directions, consequently asymmetry happens.
To solve this problem, Phép Hoán-nh ‘Changes’ accept asymmetry but under the condition that all elements of the object must stay intact.
In other words this means the resulting image must be  obtained by one of the three symmetry-methods; only the place where it will be set is in violation to symmetry rules.
Description: KY LO part 5 CHANGE by MIRROR sent to Edio 170417For example we can make a resulting image by mirror symmetry from an original image, then set it at the place where in point symmetry method  it would be found (see picture); this is a violation to the rule but it is accepted because the resulting image has been correctly obtained by one symmetry-method, mirror symmetry . This tolerance is very important because finally the ultimate rule to make ‘Change’ could be simply taught as follows:
~      Step 1. Apply one of the three symmetry-methods to an original image -this original image is a position in you quyen- to obtain a resulting image. (So we have only three choices: mirror-image, rotational-image, and point-symmetry-image).
~      Step 2.  Set this resulting image at a place where it is coherent to the whole presentation of your quyen.             

Important conclusion

In practice, for most cases, after finishing the main version of a quyen, we perform its next part by using mirror-symmetry-method and we call it ‘doing the opposite’.
We have choices to perform a quyen with ‘two faces’ -facing South, then facing North- or with ‘four faces’ –South, North, East, West.
By convention we call the starting direction as ‘facing South’, no matter what the accurate geographic direction of the place could be.
Phép Hoán-nh, the rules of  Change’ (using symmetry) have been taught through the form of Khiem-Long Quyen , as an example,  since early 1990’s (first time in the workshop at the university of Sherbrooke, then in several Stages in Paris, and in Padova).
Since then the  methods and rules for ‘Change’  have been part of the instruction to our Black-Belts,  especially the mirror-symmetry-method is to be mainly applied. Teachers can extract some exercises from a quyen   -such as Bai-Di-Xa,  Dai-Lao, Hoanh-Son, Truong-Thien, Tinh-Mat, Tam-Nguyen-  to train their students on the rules of  Change’ ( Phép Hoán-nh).
