「Palming while erect with no-longer-integrated foot」refers to a physical SIDE and DIRECTION, THAT WAY as the place where THE CLIENT might stand while using a no-longer-integrated foot, ONE PARTY TO A CONTRACT, a polite YOU. Perhaps 48 different METHODS OF DOING something in an UPRIGHT POSTURE. Also meaning SQUARE, or SQUARED as in「something multiplied by itself」(the two feet?). The SQUARE SHAPE formed by two legs with bent knees:「Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　Alternative meanings may refer to the ways the sages equated so-called common people with scorpions.「Ten thousand, scorpion」(plenty of people or animals) with a marker stroke to indicate and emphasize area directly between the pedipalps, those claw-like pincers, and in front of the chelae (near the mouth), normally the spot where the venomous barb on the scorpion's tail will strike while it holds its prey. Curiously, the scorpion's tail is most often UPRIGHT, and arches over its body as the venom barb penetrates its victim at a 90-degree, RIGHT ANGLE, SQUARE in shape to both its body and to the pincers nearly every time. The tail strikes with the most penetration if the force is applied evenly from all sides and the tail achieves the most direct strike possible. In addition to a pair of eyes that view forward, the scorpion also has from two to five pairs of eyes (near the marker stroke again, and depending upon subspecies) on the side corners of its head for SIDE vision, enabling the animal to be keenly aware of any ACTION FROM THE SIDE.
　A scorpion employs MULTIPLE METHODS FOR ACCOMPLISHING THE SAME RESULT of attacking and poisoning prey (emphasis point, again), using a variety of combinations of two very different venoms. The scorpion behaves somewhat like the PERSON OF A HUMAN BEING in that it is the only animal known, other than humans, that appears to kiss and hold its partner mouth-to-mouth while copulating (marker again), but the animals are not actually kissing for sexual pleasure it is thought, and will copulate whilst sometimes inserting venom into its partner, again similar to humans…glyph meaning「heart, mind, spirit, feelings」(particularly the original shape) resembles both a scorpion tail and human male genitals as appendages spewing venom.
　While a mother may hatch many scorplings after each mating, it will hold them inside its body, regardless of the various male sperm packets she has gathered from her various suitors. Scorpions spend most of the time hiding underground in burrows or under rocks, an allusion to the pit holes with flat rocks as sandstone doors of early「commoner class」humans. The gestation period of scorplings is nine months or so, as it is for humans. Mother scorpions carry their young on their backs (and tails), as do humans in the Orient with slings. Scorplings are unable to fend for themselves for many months in both defense and for feeding, and rely totally on the mother as do human babies, and unlike most other small animals at birth.
