「Talented hand use」by a「soldier」or to「adjust positioning」with「emissions in all directions」as a VICARIOUS SURROGATE instead of the real thing, that is, using one's hands to relieve excess pressure of fluids contained within one's prostate gland by a seminal expression.
　「Talented hand use」with「ear」and「emissions in all directions」as some GOSSIP perhaps by cupping one's hand over the speaker's mouth and listener's ear, then to another ear, and another, and so on.「Use hands for whispering」as in cupping one's hand around one's ear as someone holds their hand cupped around their mouth and whispers into your cupped ear, with 'act as a PROXY' derived from the chain of taking news by someone who is not the original source to another person who assimilates that news.
　「Talented hand use with fluttering, rustling sounds, emissions in all directions」meaning PROXY, TO ACT FOR ANOTHER, ADMINISTER TO ANOTHER PERSON and TO ASSIST, ACTING AS A SURROGATE also relates to circle jerking, often compared by military actions by the sages in glyphs…see 欇, 爽, and 交 for details.
　Right element formerly was「three ears」(攝) meaning「from ear to ear to ear」as with「whispering some rumors, gossip, rustling sounds.」And「talented hand use that generates a whispering sound」surely does seem as if that hand may be sliding up and down a shaft of some sort. Japanese version replaces the lower elements with「emit in all directions」perhaps representing gossip in addition to, literally emissions in all directions.「Ear」resembles the shape of a vertical flag attached to a pole used in China and Japan to identify soldiers as belonging to one side or the other of a battle, and「use both hands」with「many flags, ears」means to TAKE IN, ASSIMILATE and use as SURROGATES, PROXIES those soldiers who suddenly switched sides during a battle, a rather common occurrence it seems throughout history. Rumors of the enemy's strength spreading through the troops from man-with-flag to man-with-flag (or, ear to ear) may well have been the reason for the defections or desertions. Clearly, rumors would spread much faster among foot soldiers facing death while huddled among the trees awaiting an order to charge up a heavily fortified steep hill much more quickly (in seconds) than scattered serfs hoeing gardens among the hills and valleys (may take years) sparsely populated with old folks.
