Formerly 鬥, with the king's officials and guards on each side. See that glyph for details of why it also refers to a gateway. Chinese euphemism for the vaginal vestibule is the 'jade GATEWAY' by no coincidence, and significantly most forms of jade and gonorrhea gleet are various shades of green. For further details, see also 魏 as the folks who controlled access to and from the gates.
　While some ancient sites did have high walls and gates surrounding the entire city, relatively speaking those places were few in number. Not only were such high walls a great expense, walls also tend to impose limits upon growth, and eventually could lead to starvation of the inhabitants during a prolonged siege. Be sure to see 砦 for an explanation of why, generally, much smaller specialized areas within a populated district were surrounded by guarded walls and gateways, such as around a castle or a zone of particular importance, special use, or treasure.
　Describes low soil walls and GATEWAYS patrolled by guards that delineated special districts and villages commonly located near a lord's castle that housed the prostitution zone with nightly, and perhaps daily as well, entertainment establishments, with gateways as inspection stations, restricted entryways, a self-contained city area as a separate community having its own specialized methods that catered to a specific kind or class of patron, but also its own local laws, government regulations, customs, and even language at times that apply within an administrative division at the local government level, patrolled and policed by brute squads. Imitating another great invention of the Chinese, in Japan the floating world was renowned and「…evoked an imagined universe of wit, stylishness, and extravagance—with overtones of naughtiness, hedonism, and transgression. …The Yoshiwara Pleasure Quarter: The sole licensed red-light district in the city of Edo (present-day Tokyo), the Yoshiwara was a walled and moated compound of about twenty acres. First established in 1617 near the city's center, the Yoshiwara was relocated to the northeast forty years later. During the quarter's heyday, from the late seventeenth through the mid-nineteenth centuries, countless men made the journey—a trip of some two miles—to reach the quarter's fabled Main Gate (Omon). Within the Yoshiwara's walls were teahouses, shops, and more than a hundred brothels arranged in a rectangular grid, divided from end to end by a main street, Nakanocho. The streets were lined with logo-like crests and names indicating the locations of brothels and other businesses. Music, food, and drink were all on offer, but prostitutes were the star attractions of this bustling city within a city. By the end of the eighteenth century, more than 4,000 prostitutes worked in the Yoshiwara. Ranked by brothel owners according to skill, cost, and services, the most expensive were elite courtesans, whose professional names were passed down from a woman to her successor within the brothel. Rigorously trained in music, calligraphy, poetry, and other refined arts [nod nod, wink wink], these women were accessible only through strict protocols, requiring huge payments and tips at three preliminary meetings. Other prostitutes sat in latticed showrooms, on view to prospective clients. At the bottom of the hierarchy were moat-side prostitutes, whose services were quick and inexpensive. Many Yoshiwara prostitutes, including those promoted by brothel owners to the highest ranks, started life in impoverished homes in the countryside. Taken from their families, they were brought to the quarter, trained, and typically bound to brothels during the term of a ten-year contract.」

　A GATEWAY, a guarded point of entrance into a walled, closed, restricted area (see 閡): gates and gateways without surrounding walls and some armed guards are meaningless, as any burglar can attest.「Inside array of buttocks, on both sides」to depict the entrance to the brothel zone where conflicts and disputes were common between potential clients and inspectors, but also among jealous service providers. Not coincidentally employing the same elements as two「door」glyphs but in a slightly different arrangement. Or「rod, stream with tonguing mouths」as KNACK, a PARTICULAR ABILITY especially one difficult to explain or teach that must be learned by doing oneself, INGENIOUS, RESOURCEFUL, HIGHLY TRAINED by a skilled master-craftswoman.
　The gates were also used as CHECKPOINTS and INSPECTION STATIONS staffed by government administrators during severe outbreaks of infectious disease and of course to collect excise taxes, bribes, and various fees, verifying that the「much meat」entering this particular brothel zone and prostitution quarter within surrounding low walls was sufficiently healthy to enable participation in religious rites, being temporarily sent to heaven.
　Perhaps multiple「meat, female friends」side by side (朋) acting as a door or depicting what is inside the gate,「much meat.」As depicted in the glyph, one can imagine that the gate is open and the inner leg of each person is not visible, a set of two「mooning positions」that one must pass by in order to enter and join a particular group among the fray within one section of shaman town, the quarter with temples of love and shrines full of divine service providers, or as temptation not to depart quite yet. This identical business practice is still extant today, although somewhat less overt (sometimes), using sexy female models to sell everything and anything by first attracting attention using both the male and female human being's innate desire for sex.
　It is important to note that GATES can be used to keep people in, prevent them from escaping, and remain held against their will to depart just as much as gates can be used to keep others out and prevent entry. The shaman's service providers had no-longer-integrated feet to prevent their escape, and the fundamental elements of each of the two「meat」glyphs (⺼) are congealing no-longer-integrated feet (习), which should come as no surprise.
　「Most people call the whole kit and caboodle between a woman's legs the 'vagina' but the compendium of visible outer parts is technically the 'vulva.' Meant to keep dirt and bacteria out while providing a welcoming environment for worthy partygoers, the vulva is like a VIP lounge where the clitoris is the DJ. 'The labia majora (outer lips) are a protective layer of fat covered by the skin and hair,' says Dr Lillian Schapiro, a gynaecologist. Their job is to keep sex comfy even if your pelvis is bonier than Iggy Pop's. Located inside the labia majora (though sometimes extending beyond them), the labia minora, or inner lips, act like a pair of swinging doors guarding the entrance to the vagina and the urethra, the tube that leads from the bladder. 'The labia minora are much thinner than the labia majora and even more sensitive,' says Dr Schapiro. Plus, they contain erectile tissue, made up of clusters of tiny blood vessels, which means they become slightly stiffer (though not as stiff as the clitoris) during arousal. The anatomist who named the parts of the vulva must have found it lounge-like too, because the area between and including the inner folds of the labia minors is called the 'vestibule.'」

　ENTRY WAY or PATH FURTHER IN, and A MANNER IN WHICH TO DO SOMETHING as compared with a different way of achieving the same general result. Various designations of CATEGORY, or a CLASS of the same GROUPING, LESSONS, and CLEVER TALENTS, TEACHINGS OF AN EXPERT OF SOMETHING SPECIAL OR SPECIFIC:「rod stream from tonguing mouth」(doubled, multiplied) indicate all these original Chinese meanings.
　May also relate to what today is an identification and age verification procedure, such as when someone is attempting to enter a bar, purchase alcohol or smokes, and needs to show some ID. Appearing as do small swinging saloon doors, this structure is not capable of keep anyone out who truly wishes to enter—the shape is neither solid nor joined and there is no crossbeam across the middle. Note that in the Orient, most gates to a home, or of a castle, temple, shrine, or other such institution are thick, heavy, solid panels and not half-sized, flimsy saloon doors…these「gates」are not large, rectangular, hinged, top-to-bottom panels, as the glyphs which include this element clearly indicate, in addition to the strokes of the glyph itself. Not much is needed to contain young chicks and bunnies with broken foot bones.
　COUNTER FOR CANNONS refers to the HUGE DISCHARGES and BLASTS into the depicted「tonguing mouths with rods streaming」as the gateway to further masterful pleasures inside, the BIG GUNS.
