In addition to the obvious meaning of these combined elements, possibly describing some sort of sexual harness used to enhance the experience, devices that were commonly used in China since before the beginning. A type of leather harness suspended from above that held a person by the legs behind each knee in a position where not much movement was possible. With the knees up by the armpits and torso lowered into this SWING, the groin was naturally pulled wide open and could not be closed by the occupant. Very little effort was needed to move laterally for long periods as a male(s) penetrated various wide-open orifices from the front and rear, or a bevy of service providers plied their skills upon an immobile patron. See 'leather with emphasis on open crotch' (靫) that means 'to quiver' that suggests there may have been a waiting line of willing occupants wanting to climb into the swing for a long ride.
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.
