「Exchange of vaginas」as the place where the upper-class merchants and royals went in search of fresh meat, new pussy, since what was available within cities was more than likely tainted meat, infected.「Exchanges at scorpion burrow pit hole homes」or「exchange of orifices for inserting penis in vulva」(original right element was 邑) suggests being out of skirts, referring to swapping females rather than buying more, since the rural folks were not as wealthy, living far away or OUTSIDE THE CITY where the fresh, young females were marketed and sold, the OUTSKIRTS of a city, thereby entering the area of smaller villages in RURAL, or SUBURBAN areas that are today the home of people COMMUTING, SHUTTLING back and forth, into and out of a larger metropolitan area…note however, that commuting daily from suburbs into the city was not done in the days of the sages, and so is a modern interpretation. OUTSKIRTS as used here may be rather literal, since the elements can be interpreted as「circle-jerking pussies」where folks might then literally pull something OUT for a SKIRT Weinstein-style, perhaps expressing some disdain for the more RURAL, SUBURBAN areas encircling the outskirts and not in the heart of the big city.
　Regarding bonobos:「Female dominance is established first by seniority and then by affiliation to the senior female. Female bonobos constantly engage in tribidation, genital-on-genital contact. This sexual activity appears to be a means of reinforcing social bonds and of climbing the social ladder. (Dominant females were found to engage in these activities least frequently, indicating the stability of their status and the desirability of sexual exchanges with them.) Females leave their family groups as they mature, forcing them to court the affections of the dominant females of the new groups they hope to join.
　Lest you think that homosexual exchanges are exclusively sapphic [i.e., female homosexuality], male bonobos frequently engage in mutual masturbation for a variety of social reasons as well. Interestingly, bonobos are the only species aside from humans that engage in face-to-face intercourse and tongue kissing.
　This constant sexual activity of bonobos' may account for another major difference between chimp and bonobo societies. Reproductive behavior in chimps can turn into a violent affair. Females are often taken by force sexually, and young offspring may be killed by males competing for sexual dominance. Mating is allowed according to male hierarchy. Subordinate males are violently discouraged from obtaining sexual access to females. Bonobo females, however, are approached respectfully by prospective partners and males abide by their refusals. Infanticide has never been recorded in the species.
　This startling difference can be accounted for by the fact that female chimps are sexually receptive during only a short period of their cycle, meaning that sexual encounters with them are at a premium. Female bonobos constantly mate, regardless of where they are in their cycle. This has the added advantage of making paternity impossible to determine and thus making violence against their offspring unlikely. Why would a male bonobo kill a juvenile who might be his son or daughter?
　It is worth noting that violent behaviors are not exclusive to chimps, nor are sexually lubricated exchanges native only to bonobo populations.」

　Further note that human DNA is more like that of bonobos than any other species, being almost identical, which is to say that the instinctual part of the brains of each species are hard-wired in the same manner.
　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
