Glyph is the equivalent of 的 meaning「a possession, targeted」: emphasis stroke on「lamed feet, no-longer-integrated foot, tension for a long time, gasps with taut, bound on the other side, too」that denotes the POSSESSIVE CASE grammatically: THIS THING IS MINE. Based upon old texts, scholars say this glyph refers to「feet, steps」and was the source glyph for those related elements. Refers to OWNERSHIP of another human being as a sex slave or as a concubine, humans who were bought, sold, and traded as professional sexual service providers for the wealthy and royalty, initially. The hallmark of a concubine was dis-integrating the bones in each foot so that she was lame and unable to perform field work, then tightly binding each foot with a long cloth. Some fonts display the top stroke not as an emphasis marker stroke, but instead as an upper fistula drawn in the middle, which is the oldest form of「tension long time with gasps, no-longer-integrated feet.」
　「Bound feet were once considered intensely erotic in Chinese culture. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's [no-longer-integrated] bound feet」(after removing the binding cloths, of course)

　「Viewing women as commodities [see 品] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

　As depicted in erotic Chinese art, men in dynastic China masturbated by wrapping no-longer-integrated feet around an erect penis ostensibly to lower the risk of contracting a sexually transmissible disease or infection that often occurred when performing coitus within some sort of mucous membrane system of a female service provider, and, to gain hand-control over the pressure applied to the foot meat surrounding a weakened penis that functioned as a living cockring.
