The FORTIFIED PATROLLED PERIMETER WALLED areas surrounding castles were filled with various entertainment-providing businesses (simplified Chinese variant of 垒 'much loose dripping stink with feces, ground') with A STRONG HOLD on their noble clientele, and secured by a low wall that was patrolled, gated, and guarded. Formerly a set of three (many)「filled plugged screwing in orifices」over「soil, feces」(壘) an obvious representation of the four lower orifices of a no-longer-integrated-foot concubine, and much later, to a baseball diamond with a small mound in the center. Japanese variant uses four center marker elements, or「emissions in all directions」meaning「sticky」but with no internal「stream」element, suggesting a dry stickiness to replace two of the「filled muck orifice」elements. Meaning different BASES. The diamond shape of a person's two no-longer-integrated feet/skin slits being held in hands with emissions on each side, a filled orifice as 'second' and the anus as 'home' is unmistakable. Note that after arriving home (里), running other bases was no longer advisable, nor permitted by most rules of engagement.
　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.」
