「Inducing one」or「smooth progression array」or「palming orifice of/with/by child」as it refers to UNRESTRICTED USE and to ENJOY WITH NO LIMITATIONS, hedonistic INDULGENCE, and UNRESTRAINED GRATIFICATION, to OBTAIN BY PAYING A FEE…no mention here of whether the palm is the child's, or a part of someone else's hand, or part of the lord's harem, but any interpretation may have been applicable:「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　Sex with children was/is common worldwide:
　「Historical accounts from the 18th century indicate that adult-child sex (particularly same-sex pairings) were an accepted practice in China, Japan, Africa, Turkey, Arabia, Egypt, and the Islamic areas of India (Trumbach, 1977). In 19th century London the going price for a virginal, 12-year-old girl, of good background, was reported to be 400 pounds (Bullough, 1964).」

　「Like humans but unlike chimps and most other animals, bonobos separate sex from reproduction. They seem to treat sex as a pleasurable activity, and they rely on it as a sort of social glue, to make or break all sorts of relationships. 'Ancestral humans behaved like this,' proposes Frans de Waal, an ethologist at the Yerkes Regional Primate Research Center at Emory University. 'Later, when we developed the family system, the use of sex for this sort of purpose became more limited, mainly occurring within families [i.e., incest]. A lot of the things we see, like pedophilia and homosexuality, may be leftovers that some now consider unacceptable in our particular society.' 」

　Elements as「palming orifice with spermatozoa」or as「palming orifice until completion, full cycle」by a female「inducing one」also being a reference to UNRESTRAINED GRATIFICATION, UNRESTRAINED USE in order to CURE A FAILING OR DEFECT after the male has ejaculated, prematurely in her opinion and prior to her own climax, also described by the elements as「smooth progression with array of horizontal motions.」…but you'll have to complete that scene with your own imagination.
　「Tall building, grain silo」with lower element of「maggot」meaning to be given all the food or other pleasures swarming like maggots one can possibly ENJOY WITH NO LIMITATIONS. Maggot heaven, insectopia.
　「Maggots in the emperor's palace」meaning to BE GIVEN UNLIMITED ENJOYMENT of pleasures all around and「willfully accepting them」as INDULGENCE, UNRESTRAINED GRATIFICATION, to GORGE UPON pleasures while swarming like maggots. Note that a「grain silo」is also used as a phallic symbol.
　「Palming orifice with maggots」perhaps refers to CLEANING A FESTERING WOUND OR INJURY, CURING A FAILING OR DEFECT which you have been unable to correct by yourself with other means. By allowing the maggots to GORGE UPON the putrid flesh the wound can begin to heal:「Maggot therapy is also known as maggot debridement therapy (MDT)…It is a type of biotherapy involving the introduction of live, disinfected maggots (fly larvae) into the non-healing skin and soft tissue wound(s) of a human or animal for the purpose of cleaning out the necrotic (dead) tissue within a wound (debridement) and disinfection. …Written records have documented that maggots have been used since antiquity as a wound treatment. …Maggots clean up the already dead tissue thus preventing further infection spread. …In January 2004, the U.S. Food and Drug Administration (FDA) granted permission to produce and market maggots for use in humans…. The use of maggots to clean dead tissue from animal wounds is part of folk medicine in many parts of the world. …Maggots are contained in a cage-like dressing over the wound for two days. The maggots may be allowed to move freely within that cage, with the wound floor acting as the bottom of the cage. Or the maggots may be contained within a sealed pouch, placed on top of the wound. The dressing must be kept air permeable because maggots require oxygen to live. When maggots are satiated, they become substantially larger and seek to leave the site of a wound. Multiple two-day courses of maggot therapy may be administered depending on the severity of the non-healing wound.」

　As for being able to see and research spermatozoa:「According to an ancient Chinese text, the Chinese viewed magnified specimens through a lens at the end of a tube, which tube was filled with varying levels of water according to the degree of magnification they wished to achieve. Ingenious, effective and repeatable in the home, today. That this occurred some 4,000 years ago in the Chow-Foo dynasty and more than 3,500 years before the 'father of modern microscopy' was born is quite remarkable. That these Chinese ancients achieved magnification levels of 150 times today's standard, or 100 moou, is breath-taking.」

　Not likely a reference to palming orifices with rats, although gerbil stuffing (「rats」) is not unheard of for「inducing one」(that's a fact of modern human society, and not one of our jokes).
