# Device to Fix The Two Feet and Train The Kua

by on 2022/11/22

In Practical Method, we are constantly seeking methods to actualise simple principles and concepts into physical reality. During Master Chen Zhonghua’s online class on 16 November 2022, he showed a device to fix the two feet.

The below is my attempt to follow this method and help begin a discussion on how this works and how to use it.
The objective is to fix the two feet and train the kua.
• Assuming a right handed half horse stance, the left foot is placed at 90 degrees and the right foot is placed at 45 degrees.
• To create the device I used a timber skirting board that is 2cm thick and a jigsaw.
• One rectangular board is required to fix the left foot.
• One right angled equilateral triangle board is required to fix the right foot.
• In order to fix the feet position, cut out the curve of your shoes. A minimum of three contact points is required.
• To anchor the two boards, you must find a suitable space. I used a narrow space with two corners. Note that in order to fix a position, three dimensions are required.
• This is to actualise the concept of fix the two ends and move the middle.
• Progressing this idea, we can place a third fix by placing a restriction on the top of the head, but that is a topic for another discussion.
By firmly fixing the two feet, ankles and knees, we find how stuck we are on the kua.
