SANDALS, SLIPPERS formerly made from twisted hemp fibers were worn only by peasants, serfs, pissants, the「low classes」who were pleased to finally have footwear of any sort rather than working barefooted:「buttocks loitering in a tall and proud pose, braggart」showing off his new footwear. Sandals often soon begin smelling fairly foul due to being worn on the bottom of one's feet, something to recall also is affected by foot-binding.
　Then again, also suggestive in dynastic China of putting on and wearing some TEMPORARY FOOTWEAR made SLIPPERY with one's own stringy threads, i.e., the no-longer-integrated feet of a service provider working barefooted: see 蹻「buttocks, genitals loitering with aimless motions and young person's two orifices in spread legs」rather than describing HEMP SANDALS per se. Elements depict the life of a dynastic Chinese service provider working solely with her no-longer-integrated feet, so-called FLIP-FLOPS due to the arch bones of each foot being in a pulverized condition. Men in dynastic China masturbated by wrapping the erect penis with no-longer-integrated feet. See Chinese erotic art for details:
　「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. Binding usually started during the winter months since the feet were more likely to be numb, and therefore the pain would not be as extreme. …To enable the size of the feet to be reduced, the toes on each foot were curled under, then pressed with great force downwards and squeezed into the sole of the foot until the toes broke. The broken toes were held tightly against the sole of the foot while the foot was then drawn down straight with the leg and the arch forcibly broken. The bandages were repeatedly wound in a figure-eight movement, starting at the inside of the foot at the instep, then carried over the toes, under the foot, and around the heel, the freshly broken toes being pressed tightly into the sole of the foot. At each pass around the foot, the binding cloth was tightened, pulling the ball of the foot and the heel together, causing the broken foot to fold at the arch, and pressing the toes underneath. …It was generally an elder female member of the girl's family or a professional foot binder who carried out the initial breaking and ongoing binding of the feet. This was considered preferable to having the mother do it, as she might have been sympathetic to her daughter's pain and less willing to keep the bindings tight.」
　「…The tightness of the binding meant that the circulation in the feet was faulty, and the circulation to the toes was almost cut off, so any injuries to the toes were unlikely to heal and were likely to gradually worsen and lead to infected toes and rotting flesh. If the infection in the feet and toes entered the bones, it could cause them to soften, which could result in toes dropping off. Although, this was seen as a benefit because the feet could then be bound even more tightly. Girls whose toes were more fleshy would sometimes have shards of glass or pieces of broken tiles inserted within the binding next to her feet and between her toes to cause injury and introduce infection deliberately. Disease inevitably followed infection, meaning that death from septic shock could result from foot-binding, and a surviving girl was more at risk for medical problems as she grew older.」
　「At the beginning of the binding, many of the foot bones would remain broken, often for years. However, as the girl grew older, the bones would begin to heal. Even after the foot bones had healed, they were prone to re-breaking repeatedly, especially when the girl was in her teenage years and her feet were still soft. …Bound feet were once considered intensely erotic in Chinese culture…. Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　Elements depict IMPROPER ATTIRE and IMPROPER BEHAVIOUR to perhaps the greatest extent possible:「smelling of excrement, aimless motions loitering and staggering about」that seems to have all been encapsulated by the idea of SERF'S FOOTWEAR…noting that female serf feet were the most common item used in dynastic China for slip-sliding away and slipping into darkness, SLIPPERS as temporary footwear. References to a drunk copro-necrophiliac need no explanation, probably.
