「Cover, control orifice, surrounded with pigs」or「expensive concubines」or a「haughty swine」or the「pig with control of the surrounding mouths and orifices」or「tall expensive high house」(multi-storied castle on a hill) refers to the LOCAL FEUDAL LORD, a STRONGMAN TOUGH GUY with an army of spears protruding in all directions, quills with barbed tips.
　A QUILL used as a writing implement is a STIFF, HARD, UNBENDING hollow shaft that oozes black fluids mixed with clay after being dipped (into ink) as it is scraped along a surface similar to a feudal lord's pecker, or so the serfs were led to believe.
　「Pig surrounding to control mouth and orifices」also describes a PORCUPINE that rolls itself into a ball when threatened, covering and surrounding its soft parts and orifices with 30,000 erectile QUILLS protruding in all directions.「Tall on all sides pig」also as PORCUPINE (note 'porcine' or pork in the English also, as「pig with thorns」like the needles of a pine tree). Porcupines are quite large, slow, short legged (they seldom, if ever, run), fearless rodents (and not pigs actually). Porcupines must ingest a large amount of salt to maintain their metabolism, hence to obtain salt, the animals are in fact quite BOLD and FEARLESS (or, stupid), and will eat nearly anything that smells salty (feces are often quite salty) being UNINHIBITED by nature. As a porcupine moves, its long, hollow quills rattle together, making a rather loud noise announcing their presence, again unafraid of the consequences: a tiger or lion will need to have become quite hungry before thinking it may find any supper within a porcupine hide, since it must get past all those sharp quills, first. Large cats don't always lose the battle, but porcupines do not need to flee a challenge, and often simply roll up, erect their 30,000 odd quills with barbed tips, and wait.
