纏足とは：「…少女の足がそれ以上成長しないように、痛みを伴うほどきつく縛る習慣。…通常、少女の家族の年長の女性、またはプロの纏足師が、最初に足を折ってから継続的に縛ります。母親が行うよりも、母親の方が好ましいと考えられていました。母親は娘の痛みに同情し、縛りをきつく締め続けることを好まなかったかもしれないからです。」
「…縛りがきつかったため、足の血行が悪く、つま先への血行がほぼ遮断されていたため、つま先の傷は治りにく く、徐ーに悪化して、つま先の感染症や肉の腐敗につながる可能性が高かった。足とつま先の感染症が骨にまで達すると、骨が軟らかくなり、つま先が落ちてしまう可能性もあった。しかし、足をよりきつく縛れるため、これは利点とみなされていた。足指に肉質が多い少女の場合、足の横や足指の間にガラスの破片や割れたタイルの破片を挟み込み、故意に怪我をさせたり感染症を引き起こしたりすることがありました。感染症に続いて病気が起こるのは避けられず、つまり、纏足が原因で敗血症性ショックで死亡する可能性があり、生き残った少女も成長するにつれて健康上の問題を抱えるリスクが高まりました。」
「縛り付けが始まった当初は、足の骨の多くが折れたままで、何年もそのままになることも多かった。しかし、少女が成長するにつれ、骨は治癒し始めた。足の骨が治癒した後でも、特に少女が10代で足がまだ柔らかい場合は、繰り返し再び骨折する傾向があった。…中国文化では、縛られた足はかつて非常に性的指向のものと考えられており、完璧な蓮華足を持つ女性は、より名誉ある結婚ができる可能性が高かった。清朝の性行為取扱説明書には、縛られた女性の足を使った遊び方が48種類も記載されています。…縛られた足は、女性を家族、特に男性に依存させ、貞操と男性の所有権の魅力的な象徴となりました。なぜなら、女性は主に家の中に閉じ込められ、護衛や用心深い使用人の助けなしには遠くまで出かけることができなかったからです。」

　A STONE ROLLER was used to dis-integrate and re-dis-integrate feet that had begun to mend internally.
　FOOT binding was:「…the custom of applying painfully tight binding to the feet of young girls to prevent further growth. …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, 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. …Bound feet rendered women dependent on their families, particularly their men, and became an alluring symbol of chastity and male ownership, since a woman was largely restricted to her home and could not venture far without an escort or the help of watchful servants.」
