Many have asked me what is a good indication of yjkym.
My reply , when standing in yjkym , the top bottom , left right, up down , all in synchronize at every move. There are no force full tension in the body or joints needed.
A Wck yjkym is a nature physiological state, not a fix stance.
Thus, Wck yjkym is not about holding any type of geometry shape. Because Wck yjkym is using the optimal human natural body structure to support the natural forward movement. Since Wck doesn't do sideward movement . It doesn't have to hold or made a optimal human natural body structure. One just has to return to that natural structure. Thus, yjkym is about return or drop back to the natural state . It is not about forcing or holding a share or structure. Why? In real life dynamic, holding a fix structure is just make dynamic clumsy. Not to mention man made structure always turn into problem like process food.
So, do one use yjkym in fighting? Do you use your natural optimal body state in fighting? Is your yjkym is about tries to develop some thing some ideas some one telling you? Or is your yjkym is about the more you practice the more you get close to your optimal natural dynamic instinct?
Many has said Wck is not an animal style but a human style.
However,
Does making yourself to become a water tower and following geometry lines scientifically similar to a robot a human style? So, does 1850 has robot style ?
IMO. Gm Ipman is explaining the natural of Wck with the geometry language in 1960 hng kong, but instead many take geometry as Wck. But wait a minute, in 1850 china, there is no such things as western geometry.
The yjkym is difficult because it is willow, rattan, snake, coil spring, but not southern fist and not robotic fist and not animal style.
