Literally, the「gateway, methodology, section」with「orifices connected by backbone.」…the COCCYX ends the spine just above the anus, with the other end of the spine near another orifice, the mouth, leading to potentially representing「two orifices connected by a backbone between them」that is highly suggestive of the「ménage à trois methodology section.」VILLAGE is also represented in many glyphs by that other female orifice in the groin near the coccyx, the vagina.
Sources suggest 25 families who all get together and build a fence around their pit holes and add a gate, although, such a plan does tend to stifle growth and may be indefensible from armed bandits by only 25 serf families…however, the fence might additionally help keep rabid bands of marauding coneys at bay. RURAL AREA may likely refer to areas with wet, muddy spots for implanting near the coccyx.
Refers to a VILLAGE that is not always some remote place way out in the countryside, but also are special districts, zones, quarters within a larger city or town, often in the old days marked by surrounding walls with SOIL SLOPES and gateways as checkpoints, restricted entryways, a self-contained city area as a separate community having its own specialized business establishments that cater to a specific kind or class of patron, but also its own local laws, government regulations, customs, and even language at times that apply within an administrative division at the local government level, patrolled by police. Used as a euphemism for both the HUMAN BUTTOCKS or the VULVA, both having a similar design and shape of rounded sides with a wet hole in the center, albeit on a different size scale (generally). As an element that appears on the left side of glyphs, denuded terrace-farmed SOIL SLOPES with trees removed, covered with stinky fluids, muck, and fecal slurry fertilizer in clay-lined paddies, and therefore NAKED. When it appears on the right side in glyphs, means「scorpion burrow, downward spiral into slippery slope orifice」as a VILLAGE or as NAKED FEMALE GENITALIA, the birthplace of every human being who has ever lived, the hole (邑) into which the「scorpion tail, appendage spewing venom, human penis」disappears and dwells for a time.
