Both the two ends of an archery bow「resemble」each other, and also these bow ends resemble something of the「miniature meat」of surrogate orifices in no-longer-integrated feet, in particular the two ends of these feet, the large toe on each foot…the big toes remained unno-longer-integrated, if possible, and protruded as do the ends of an archery bow where the「threads」of the bowstring were strung. The big toes also partially served as anchors for the foot binding cloths in dynastic China that were tightly strung around each foot in an arched shape formed from many figure-eight loops:
「…[T]he custom of applying painfully tight binding to the feet of young girls to prevent further growth. …The process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …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. …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. …Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」
