To BECOME LIMP, FLEXIBLE, WOBBLY, MOVING BACK AND FORTH as「wheels in axle with gap」that describe a loose wheel.「Rotation of plugging orifice」with「deficient, decapitated (now headless), yawning, gaping」appears to be LIMP, become wobbly, or FLACCID. Any such rotation plugging orifices and/or among gaping mouths would eventually cause a male to GO LIMP, FLACCID.
　Right element was「pliable, flexible」(輭) formerly depicted by「beard big」(big beards really are soft) or「rotation of plugging orifice with pubic hairs having two hands underneath」as enough to SOFTEN anyone's moral resolve, perhaps with some quivering motions and a little whimpering or moaning, too most likely.
　Japanese lists meaning of jujitsu, jiu-jitsu, jujutsu that today is mostly written as 柔術 or「gentle, soft techniques」and these glyphs also deserve to be investigated by individual element in detail for a full understanding of that art.
　Modern right element of「gaping mouth, blowing」has replaced the soft, long beard, and it is also possible to SOFTEN up some females by a「rotation of blowing on her orifice(s) for plugging」although it is reported that a certain level of skill and experience is required for success, but a skill learned early in life by the ancient Chinese, no doubt.
　Alternatively,「cart wheels rotating on gaping or bearded necks」will likely cause the victim to GO LIMP either sooner or later, and certainly the mere thought would do well to SOFTEN, MAKE PLIABLE the will of most peasants as royalty passed on by while enjoying the sport of kings, because if not, it was easy to find oneself down in the dirt alongside a wheel rut minus one's head (「shortened, decapitated, blowing hard as the blood pressure dissipates, gaping」and so on), after which your body will most certainly be LIMP, FLACCID, SOFT and PLIABLE as the royal carriage rolls along WOBBLY, MOVING BACK AND FORTH over the neck, at least until rigor mortis sets in or your cadaver is cooked.
　While the following explanation is not suggested as a mnemonic, scholars explain this as wheel gap, wrapping grasses or reeds around the outside of the wheels on a cart to soften or cushion the ride as「bearded wheels」that created a「gap between the wheels」and the road surface (maybe so?).
