Curiously, both Japanese and Chinese sources list no vocabulary containing this glyph, nor do either provide a definition. Possibly describes the places of ORIGIN of the human species, the PLAINS and SAVANNAH, PRAIRIE—but it remains to be determined how the ancient Chinese may have known this. Flat land of a PLATEAU, PLAIN, PRAIRIE, also as an ORIGINAL state or condition of land prior to human habitation, the wilderness. Humans and most other land-based life on Earth cannot survive without a source of fresh water. Internal elements are「white, conspicuous and water」perhaps depicting a source of fluid as the head of a fountain with rocks that has spurted onto a flat, level area, such as the lower torso between the umbilicus and pubic bone of a person lying supine.
「Cliff」with「conspicuous white open-tonguing mouth」and「water」describes the ORIGIN, SOURCE, PRIME, RAW, CAUSATION of both early cave-human FORMER, PRIMITIVE dwelling places and PRIMAL human behavior, but also describes the infamous caves of wonder, the ORIGIN of soothing business enterprises of all types, divine religious experience, medical practices of witch doctors, and accounting practices with barter and later coin money as the foundation of modern human civilization: THE FIRST HUMAN PROFESSION, the FORMER preferred method of clients with service providers causing ejaculation-for-money (fellatio) prior to foot-dis-integrating and the rampant transmission of sexually-related disease and infection.
「Array of erections」or「hand」with「torpid blank stare, white water stream」depicting the ORIGINAL and likely FIRST, PRIMAL, FUNDAMENTAL method employed by male humans (and bonobos today imprisoned in a zoo), extracting the SOURCE of RAW fluid, The ORIGIN of Species…still practiced today for that matter by humans, too, a result of purely natural selection.
「Arrayed erections with/for money and wealth, conspicuous white water」or「array of open tonguing mouths for erection water」as the ORIGINS of human civilization and society, the first profession of selling sexual services.
