A SERIOUS ILLNESS is suggested by someone often「bending over in lordosis position and regularly masturbating」as one method of dealing with chronic prostatitis.「Horse among bamboo」as UNHURRIED, DELIBERATE, SERIOUS horse that STEPS VERY CAREFULLY. Cut bamboo with pieces laying closely together on the ground or drying obviously will cause a horse to slow down and to STEP VERY CAREFULLY to avoid breaking a leg. Chasing wild horses into areas prepared in this manner was a technique used to hunt and trap the animals, formerly as a high-protein human food source. Top element of「bamboo」described as「heads down, streams of kowtowing prone」with「horse」may depict a rider bending over and watching the ground very carefully while moving slowly an UNHURRIED, DELIBERATE, SERIOUS manner, perhaps while tracking someone. Mature bamboo plants bend over and bob in the breeze as if kowtowing continuously and grow quite thickly in groves, making the path ahead, and the ground, rocks, and other CRITICAL obstacles difficult to see and to move quickly while among the plants, hence the horse must walk DELIBERATELY. If there is no path through the bamboo, the horse will move all that much more slowly, SERIOUSLY and deliberately.「Head down and streams of kowtowing prone」is also the basis of CORDIALITY.
　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.
