「Bowing, arched shape」with「up-down vertical motions」or something dropping「vertically from within」(tears, a runny nose?) or「end-to-end, side-to-side, top-to-bottom high tension for a long time with many gasps」depicting someone in MOURNING, GRIEF, ANGUISH over a DEATH.「Foot binding cloths removed top to bottom」may suggest that the person who died was a young girl from septic foot infections and gangrene, or a client.「Rod within folded-over no-longer-integrated foot」as the principle reason for that practice causing depicting MOURNING, GRIEF, ANGUISH, and DEATH.
A single vertical stroke also represents an「ash bowl」or an「urn」in which chopsticks are stabbed vertically during a funeral. Chopsticks are used to pluck bone and teeth remnants of the cremated corpse from the ashes prior to interment at a gravesite, with each MOURNER taking out one piece, then stabbing the chopsticks into the ashes vertically and passing the urn to the next person attending the funeral…and for this reason, never poke your chopsticks vertically into your rice bowl.
Also represents one stick of incense stuck vertically into a censer with smoke curling around it…a single stick of incense is traditionally only used at death and funerals, so otherwise use three, five, or seven, avoiding an even-numbered count that may offend superstitious folks (likely, this glyph came first and the superstitions followed because of this glyph's shape). A single stick of incense does not normally send a polite message, since it is used at funerals, obviously.
Replacement glyph in Chinese is「orifice with loincloth」perhaps as someone covering their face and mouth while sobbing and mourning to muffle the sounds and wipe nose mucus and tears, or to sniff their own loincloth for some other reason, perhaps to sniff for a similar infection as the one that killed the corpse.
Another unlikely suggestion is that the glyph depicts「shooting an archery bow vertically」however, standing and firing arrows vertically on a calm day is generally ill-advised, a cause for friends and relatives to be in MOURNING, GRIEF, ANGUISH over a DEATH. And in old Chinese, glyph represents 100 coins, with a hole in the center of each coin that is common in Asia (see 円 for the reason why), that were strung onto a long cloth pulled taut by the weight of the coins, presented to the family of a deceased person at the funeral.
