An earthenware JAR or BUCKET used to「equalize」the weight of the「terra cotta」vessel used when drawing water from a well, requiring「downward thrusting on both sides」and making it easier to haul up water by counter-weighting the lifted load using a large lever (known as a SWAPE and from whence is derived the English word「swap」), counterbalancing the JAR'S weight so that human strength is needed only for moving that portion of the weight related to the water every time water is retrieved, and not the jar, beam, ropes, and other apparatus also every time.「Two downward thrusts」(left element) also applies the principle that it is easier to pull something down rather than hoisting. It requires much less effort to raise a full bucket of water by adding counterweights on the opposite side of a large lever attached to a high fulcrum above a well and pulling down, compared to simply hoisting a full bucket from deep within a well as would be the case with only a rope and no swape apparatus. The empty bucket may then be easily and safely lowered back into the well by another person pulling down on the well bucket rope—even children, with one on each side, can operate a swape. Drawn water can be poured into troughs and used in an irrigation system. This invention revolutionized irrigation practices and greatly increased agricultural production.
A harem flower packing both orifices simultaneously or two harem members involved in a joint, reciprocal action with a tool that thrusts to both sides evenly…dildos were celebrated in ancient China, unlike the shame and embarrassment sometimes witnessed today. A dual-headed dildo, designed either for single-party (both heads in the same direction) or two-party use (heads pointed in opposite directions), such as when two harem members are involved in a joint, reciprocal action with a tool that thrusts to both sides evenly. The shape of beer and liquor bottles with long phallic-shaped necks were apparently designed for insertion into human bodily orifices as a means of quickly and efficiently absorbing alcohol and other intoxicants dissolved therein into mucous membranes such as those located within the vagina and anus, necessary for administering anesthetics on a battlefield, for example, or, while at a party with some close friends. Western witches「rode」broomsticks with hallucinogenic herbs mixed into a paste and smeared on a stick rubbed back and forth within the vulva for this same reason, an idea perhaps learned from the shamans.
