DISAPPOINTED, FRUSTRATED, DIMINISHED ENTHUSIASM, CRUSHED SPIRIT as might be the case when forced to walk upon crutches due to a severe SPRAIN,「using shoulders to move with rod taut and erect on both sides.」
Likely the source of an idiom brought back home by the British opium traders that became part of English,「having a CHIP ON ONE'S SHOULDER」: a chip is a very small piece of wood, or woody, not「the big one」and so a concubine being forced to work as a mere accessory on a very small woody, say one of the lord's young sons, would be PERCEIVED AS A GRIEVANCE, a put down, and may create the SENSE OF INFERIORITY within those concubines attending to the small WOOD CHIP OFF THE OLD BLOCK as that much bigger chunk of wood the lord possessed. Elements suggest these concubines were also changing diapers filled with feces, just to give an idea of how young the son may have been. Nonetheless, having a「very small rod within flesh seam」of these concubines would also account for PERCEIVED GRIEVANCE, DISSATISFACTION.
Forcibly「using two hands」to「sit someone down」on their heels, forcing the person down onto the floor to THWART an attack might understandably cause a SPRAIN to knees or ankles, or both, and be involved with「punishment.」One tried and true old Chinese torturing punishment was to force a person to sit back on their own heels for a long time, in Japanese as 静坐 (quietly sitting on ground) or 正坐 (correctly sitting on ground), which is the standard procedure for all guests in a formal Japanese setting.
Indicates FRUSTRATION while not being able to walk at all, a SETBACK (onto your heels). After suffering a SPRAIN, a person will LIMP ABOUT and not be able to run or walk well for a time. And sure enough, after sitting quietly and immobile with all your weight on your heals for a long time following the standard procedure in a formal Japanese setting, a person will LIMP ABOUT and not be able to run or walk well for a time (try it yourself). Probably used to control any guests who might have had a notion to attack the host, giving the host time to react and strike the attacker first (a LIMPING DEFEAT) or to run away and hide in order to THWART the attack.
「Use hands」in this glyph may also refer to how a person is supposed to move about after sitting in this manner for twenty minutes or so, KNUCKLE CRAWLING.
