四つん這いになってひざまずいている人。壁の間の道を通り抜けることを表現しており、「壁」を意味する字形に注目してください。（壁）筋肉組織の壁の間を通過する「土への肛門貫通」の構成要素を使用しています。旧改作では、「木質の、木材」構成要素（桶）が追加され、水なしで輸送される未処理の排泄物などの内容物を一時的に保持するための容器または開いた空洞の使用（例：容器またはバケツによる「下越」）。何千年も前に、道路が土壁の間をどれくらい通っていたか考えてみてください。交通量が最も多い地域でさえ、高架や地下道の建設の必要はなく、土壁は木材で補強されていても、暴風雨の際には比較的早く浸食される傾向があります。
「内容物を一時的に保持する容器」、溜まった排泄物を捨てるバケツなど、さまざまな機能（「お尻を突き出して使用」…考えてみてください）。
「ゲートウェイ」（現在は閉鎖されており、もちろん「使用中」）を「往復」して通り過ぎ、おそらくさまざまな集団間を往復しながら内部の性的奉仕を「利用」した後、四つん這いになっている人。
シャトルとは、よく知られ、頻繁に使用される、確立された短いルートを定期的に往復することであり、ある場所を通過するが、そこに短時間だけ留まることを意味します。
あるいは、まだ可能性は低いが、織機の「シャトル」が「使用中」で緯糸を経糸に通すのに使われたという説もある。シャトルは織機を操作して踏み板を踏む人の「開いた足」の上にある経糸に導かれ、織機の一方側から他方側へ絶えず通されていた（残念ながらバケツとはあまり関係がない）。

「Person kneeling, on all fours」who is「in use」depicting to PASS THROUGH, a PATH BETWEEN WALLS, noting the glyph meaning「wall」(壁) uses elements of「anal penetration in soil」passing between walls of muscle tissue. Old version added the「woody, wood」element (桶), the use of a receptacle or an open cavity to temporarily hold some contents, such as untreated excreta transported without water (e.g.,「shimogoe」via containers or buckets). Ask yourself, how often did a roadway pass between soil walls thousands of years ago? there wasn't a need for overpass-underpass construction even in the highest-traffic areas, and soil walls have a tendency to erode rather quickly during rainstorms albeit reinforced with wood.
　A「container for holding contents a brief time」as a BUCKET used for collecting feces, among other functions (「protruding buttocks, in use.」…think about it).
　From time immemorial before the beginning, humans have collected feces and used it as fertilizer. Still today, researchers are working on finding solutions for problems facing humanity. It is not only feces that are an excellent fertilizer. Urine works, too! "Innovative system turns human waste into sustainable fertilizer: Stanford researchers have developed a prototype that harnesses urine to generate valuable fertilizer, offering solutions for sanitation and energy in resource-limited regions."

　「Person kneeling on all fours」after「shuttling」past a「gateway」(now closed, being 'in use' of course) and「using」the services within, perhaps by shuttling around to the various groups.
　SHUTTLE as in regularly moving back and forth over an established, short route, one well-known and often used, to mean PASSING THROUGH but only remaining for a brief time in any one place.
　Alternatively yet unlikely, some suggest the「shuttle」of a loom「in use」to pass the weft threads through the warp threads. The shuttle continually was used to PASS THROUGH from one side of a loom to the other, guided by the warp threads above the「spread legs」of a person operating the loom and treading on the treadles (not much to do with buckets, unfortunately).
