Large「cauldron having three hollow legs.」Three points on the floor will not wobble, as geometrically three points define a plane. And yes, the glyph seems to show four legs, but perhaps the middle two strokes are each side of the same leg depicting「hollowness」(and, some fleshpots had four legs). The hollow legs often were filled with fluids, enabling the cauldron to become a steamer for dim sum, gyōza, shūmai, soft buns, and other foods when set among burning coals and flames. Modern form of this glyph as an element appears most often as「wealth, money (貝)」or using only the center element as「eyeing, goal, aim.」Actual wealth in the good old days was「meat in the fleshpot」or the「meat of a fleshpot」and was where all eyes were turned and watching.
Left and right elements are said by scholars to represent「stiff wood, planks, stiff as a board」and if so may suggest the fuel for the fire heating the central CAULDRON, FLESHPOT that sustained the system…or, stiff woody in each side, burning in heat from below (see 火), one in each hollow arch within a no-longer-integrated foot of a service provider, a long-running analogy to these fleshpots with many aspects, since no-longer-integrated feet also were hollow when curled over heel-to-toe. The Chinese fleshpot with hollow legs was at times filled partially with meat fluids, so that when the pot was placed in and above heat and flames, the meat juices would bubble, foam, seethe and percolate out of the hollow shafts, cooking foods with steam to mitigate scorching and burned supper meat.「Hollow leg」in English still refers to someone who can eat a great deal of flesh and drink plenty of alcohol, a term brought back to England from China by the opium lords and traders a few centuries ago. For this reason in China, one euphemism for an ejaculating penis is the 'short leg' (just as 'short arm' is used in the West). Hollow feet in burning embers were equated with the no-longer-integrated feet of a service provider that could devour much client meat.
