　Busted feet were a SIGN of a sexual services provider, a status SYMBOL for a concubine:「…[T]he custom of applying painfully tight binding to the feet of young girls to prevent further growth. …Bound feet were a mark of beauty that became a prerequisite for finding a husband, as well as an avenue for poorer women to marry into money. Women, their families, and [a husband] took great pride in tiny feet, with the ideal length, called the 'Golden Lotus,' being about 7 cm (2.75 inches) long. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Bound feet were once considered intensely erotic in Chinese culture, and a woman with perfect lotus feet was likely to make a more prestigious marriage. Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　Marriage is a relatively recent institution in our species’ 300,000-plus-years of history, originating perhaps 5,000 years ago in Mesopotamia, and until quite recently served to bind women to men as property assets, to ensure paternity, and protect the male's lineage among descendants. That puts marriage at ~1–2% of the age of Homo sapiens.
　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.」
