Chinese meanings interpret the elements as「no-longer-integrated foot orifices from which one must maintain distance and avoid」as a reference to the emperor's harem, or to BONE SPURS emerging from no-longer-integrated and bound feet (…as in, a spur stabbing a cock perhaps?). In Japan, where foot bones were not mashed to create hopping bunnies as sex toys, meaning「huge ankles to avoid」and possibly referring to razor sharp BONE SPURS tied (「cloth binding of feet」) to the muscular leg (ankle area) of a fighting cock, or the cock's own natural COCKSPUR. Note the left source elements are「orifice with feet in high tension for a long time causing gasping」and referred to the no-longer-integrated and bound feet of a concubine that were wrapped tightly with long cloths nearly all the time. It was soon learned that binding cloth around the leg drumsticks to attach razor blades to cocks was useful for causing the cockfights to result more often in a truly final finish, clearly determining the winners of the betting…it also helped the birds to remain standing longer, not having their own legs sliced up by the other cock, and instead causing each cock to use those really high kicks to the head and torso that are so thrilling to watch. It was a good idea to KEEP SOME DISTANCE away from both the spur and angry cock.
Fighting cocks were kept ISOLATED, or a LONG DISTANCE away from other chickens, as the cocks had been strongly encouraged and rewarded by human being masters for literally slashing and ripping other chickens to pieces with cockspurs, and the animals never really knew when to begin cutting up a neighbor, hence it was later discovered that separate quarters were needed until the hour of the big fight, else the entire flock might be rendered「ripped into nuggets」in a single afternoon, spoiling future entertainment (and profit) opportunities for screaming, wine swilling, drunken crowds of gambling onlookers, with nugget grease from yesterday's losers and other fluids dribbling from their beards. Please recall that up until quite recently, cockfighting and dogfighting were legal forms of entertainment for humans all over the world, with today's losers becoming tomorrow's lunch, literally. Humans kickfighting, boxing, professionally wrestling and punching each other is still legal, and it seems much more appropriate to permit intelligent animals to bash one another, frankly, rather than encouraging chickens and dogs to fight as a blood-sport…. Likely the origin of the cocky tough guy expression,「eat you for lunch.」…maybe, they did.
