Modern fonts use elements of「threads with the utmost whacking」that may refer to the process of weaving cloth on a loom in which the threads are「packed, whacked」together after each pass of the shuttle by a sliding bar, affectionately referred to as the「beater」(not a joke) and more whacking causes the threads to be packed more DENSELY, resulting in a FINER fabric.
　On the other hand,「ejaculation from the utmost limit whacking」is not whacking hard at all, but rather, the FINE, DELICATE, EXQUISITE gentle hand motions that prolong the experience to the「limit」causing the whackee to begin screaming for orgasmic release. Traditional fonts use elements of「ejaculations」with the「utmost, array of stinky feces」over「lying prone with spread feet and crotch」(夊) but with the ends of the legs (that is, the feet) positioned above or over the head and beside the ears, suggesting DENSELY PACKED as in the vernacular 'fudge packing' (至) with clusters of multiple buddies, albeit gentle ones.
　「Mourning garments」with「coerce」or「feet spread」or「prostrated whacking」or「feet beside ears」(varies by font) suggests a final farewell to the deceased…see 䌂 as corpse's keepsake, final gift to a departed loved-one, group necrophilia:
　「Singular accounts of necrophilia in history are sporadic, though written records suggest the practice was present within Ancient Egypt. Herodotus writes in The Histories that, to discourage intercourse with a corpse, ancient Egyptians left deceased beautiful women to decay for 'three or four days' before giving them to the embalmers. Herodotus also alluded to suggestions that Greek tyrant Periander had defiled the corpse of his wife, employing a metaphor: 'Periander baked his bread in a cold oven.' Acts of necrophilia are depicted on ceramics from the Moche culture, which reigned in northern Peru from the first to eighth century CE. A common theme in these artifacts is the masturbation of a male skeleton by a living woman. Hittite law from the 16th century BC through to the 13th century BC explicitly permitted sex with the dead.」

　Before decrying, note that cannibalism, torture until death, and necrophilia were portrayed in the original Snow White and the Seven Dwarfs by the Brothers Grimm in their children's tale.
　Without a doubt, the Irish also have knowledge of their own to pass along in these trying times:「Masturbation will not spread coronavirus, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after.」Nonetheless and regrettably, unlike in dynastic China, it must be undertaken alone to truly be a preventative countermeasure but still achieve the desired result with some degree of safety.

　The Dutch, too have the same solution—it seems masturbation has become mainstream in the media the world over due to the coronavirus (it has always been 'the main stream' in reality, albeit covertly for most folks):
　「'Don't have sex with your partner if they have been isolated because of (suspected) coronavirus infection,' the RVIM says. 'Sex with yourself or with others at a distance is possible (think of telling erotic stories, masturbating together).'」

　Needless to point out perhaps, but Chinese shamans from antiquity hit upon the same solution as a pandemic preventative countermeasure, honed for ultimate client satisfaction by utilizing naked females with no-longer-integrated feet as masturbatory sex buddies available for short-term rental with erotic visualization of live prepubescent female genitalia engaging in autoerotic stimulation herself, as a solution to the same problem facing us now, but in pre-Internet days.
