「冬の糸」は、カイコガがもう収穫できないことを表していると考える人もいますが、残念ながらカイコガの実際の自然なライフサイクルはこの説明には当てはまりません。
「卵は、成長を促すために寒い気候を必要とし、産みつけられてから6週間から12か月の間に孵化します。卵は孵化して幼虫を産み、幼虫は幼虫（イモムシまたはカイコ）に成長し、数週間かけて桑の葉をむしゃむしゃ食べたり脱皮したりします。皮膚が合わなくなると、あごもろとも皮膚を絞り出して、新しい皮膚を成長させます。4回目に皮膚を脱ぎ捨てた後、居場所を探し、繭を作り始めます。約1か月後に蛾として出現します。」
　【　https://factsanddetails.com/china/cat9/sub63/item342.html　2023-05-18　】…桑の木は冬の間葉をつけませんが、これはカイコガの幼虫が食べる唯一の食物です。冬の糸が桑の木の葉を覆っているのではないかと考える人もいます。これは、ほとんどの屋外生物の自然な年間成長サイクルの終わりを漠然と意味し、すべてが次の春に再開されますが、ほぼすべての生物がこのサイクルに従うわけではなく、多くの植物、動物、微生物、菌類などが冬の間も元気に生き続けます。これは、人間と地球上の他のすべての生命にとって幸運なことです。
結論として、完了、終わり、射精が冷めるまでに完全に完了していること…地球上で知られている中で、割合的に最も大きな睾丸を持つ動物を描いた図をご覧ください：「螽」。睾丸、足を広げた状態、頭付きの股間の2つを伴った「射精」は、顧客のビジネスが完了、終わったことを示唆しています。足を広げた状態での射精、2つの身体的状態は、膨張した状態と弛緩した状態の場合のように、完了、何かを完全に行うことを示します。
足の脱統合手続きは冬の間に起こり、冷たい石の床がいくらかの麻痺緩和をもたらすかもしれない。これらの構成要素は、脱統合したばかりの足をきつく縛る布を指して「冬の糸」である可能性の方がはるかに高く、通常の人間としての自然な成長サイクルの完了と終了、そして奉仕を提供する性奴隷としての神聖な存在への変態の始まりを区切っている。
纏足とは「…少女の足がそれ以上成長しないように、痛いほどきつく縛る習慣。…この処置は、足のアーチが完全に発達する前に、通常は2歳から5歳の間に開始されました。…纏足は、足が麻痺している可能性が高いため、痛みがそれほどひどくないため、通常は冬の間に開始されました。…清朝の性行為取扱説明書には、女性の纏足を使った遊び方が48通り記載されていました。」

「伝統的な中国医学では、小児性愛（または同等の用語）と呼ばれる精神疾患、同性愛、あるいはその他のいわゆる性的変化のほとんどが存在しません。…子供は通常、生まれながらの性的存在として説明され、性的な刺激や性行為は子供の健全な発達に有益であると考えられています。」

「女性を商品として見ることは【品を参照】宋代（960年～1279年）以降、急激に拡大した労働市場と人間関係の両方において慣習となった。男性は自分の親族の女性を奴隷や売春婦として売ることができ、実際に頻繁にそうした。」

「Thread in winter」suggested by some to depict that silk caterpillars can no longer be harvested, but unfortunately the actual natural life cycle of the silkmoth does not fit this description:
　「The eggs, which require cold weather to trigger development, hatch anywhere from six weeks to 12 months after being deposited. The eggs hatch producing grubs that develop into larvae (the caterpillars or silkworms) and spend several weeks munching on mulberry leaves and molting. When they outgrow their skin, [they simply] squeeze out [of] it, jaw and all, and grow a new one. After tossing off their skin for the [fourth] time they begin [to] find a place and [begin] making their cocoon. After about a month they emerge as moths.」
　　[　https://factsanddetails.com/china/cat9/sub63/item342.html 2023-05-18　]　Mulberry trees do not produce leaves during winter, the only food that silkmoth caterpillars will eat. Some suggest that the「threads of winter」vaguely implies the end of the natural annual growth cycle for most outdoor organisms and everything restarts next spring, yet nowhere near all organisms follow this cycle, as plenty of plants, animals, microbes, fungi, and so forth continue living just fine through the winter months, fortunately for human beings and all other life on the planet.
　As CONCLUSION, FINISH, THE END, to have DONE COMPLETELY by the time the「ejaculation has cooled.」…see 螽 that depicts the animal with proportionally the largest testes known on our planet.「Ejaculation」with「testicles, spread feet and two inside crotch with head」suggesting that a client's business has CONCLUDED, FINISHED.「Ejaculation with spread feet, two physical states」indicates to FINISH, to DO SOMETHING COMPLETELY as in the case of turgid and flaccid.
　The foot-dis-integrating process occurred during winter so that the cold stone floor might provide some numbing relief. Much more likely are these elements as the「threads of winter」as a reference to the tight binding cloths on newly dis-integrated feet, demarking the COMPLETION, FINISH of the natural growth cycle as a normal human and the beginning of the metamorphosis into a divine being as a service-providing sex slave:.
　Foot binding was:「…the 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. …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. …Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　「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.」
