Scholars say that the upper and lower portions formerly depicted「plants with the sun.」The Sun actually rising from among grass, plants on land and not from beyond the horizon in the solar system as the planet revolves is an IMPOSSIBILITY and WILL NEVER OCCUR. Another specific use is as the element FOOL, IDIOT, IGNORAMUS, MORON, DOLT, IMBECILE perhaps refers to someone completely awed by the sunrise (every morning?) and staring at the scene while gawking with「open mouth, showing tongue」as it seems to rise from land, among trees and plants, or so the person believes.
　「Screwing and coming before others prematurely」seems good to an utterly inexperienced young male, but anyone else who knows better will think such behavior befits an IGNORAMUS.
　IMBECILE also derives from the posture of standing and staring wide-eyed gawking like a geek with mouth wide open, often the posture of a person possessing a low level of cerebral processing ability, such as someone believing in unicorns and other balderdash or anagoges, or that the Sun rises and sets among plants on land somewhere. Early Chinese usage referring to Japan as the「Land of the Rising Sun」was intended as a pejorative, and was not complimentary…when deciding this new name for Japan, no one seriously believes that the Chinese were suddenly trying to be nice, right?
　Quote:
　Both Nippon and Nihon literally mean「the Sun's origin」that is, where the sun originates, and are often translated as the Land of the Rising Sun. This nomenclature comes from Imperial correspondence with Chinese Sui Dynasty and refers to Japan's eastward position relative to China. [Wrong. The Chinese were not that stupid, but they thought that the Japanese were, and so spoofed them with flattery—it was simply another disguised insult, referring to Japan as the 'Land of Imbeciles'…recall that from antiquity the Japanese have worshipped the Sun as their goddess Amaterasu. Note as well that these same glyphs together could also depict「tonguing mouth with stem of woody」that in colloquial parlance is a cocksucker.] Before Nihon came into official use, Japan was known as Wa (倭) or Wakoku (倭国)…[as] shameful (writing Japanese Wa as 倭 implying「dwarf」), and summarizes interpretations for ʼWâ「Japanese」into variations on two etymologies:「behaviorally 'submissive' or physically 'short.'」…Examples include:「Respect is shown by squatting」(Hou Han Shu, tr. Tsunoda 1951:2), and「they either squat or kneel, with both hands on the ground. This is the way they show respect.」(Wei Zhi, tr. Tsunoda 1951:13)…The second etymology of wō 倭 meaning「dwarf, short person」has possible cognates in ǎi 矮「Short person. Midget, dwarf. Low. wō 踒」「strain, sprain」bent legs and wò 臥「Lie down. Crouch. Sit.」 (such as with the lower animals and birds). …Chinese, Korean, and Japanese scribes regularly wrote Wa or Yamato「Japan」with the Chinese character 倭 until the 8th century, when the Japanese found fault with it, replacing it with 和「harmony, peace, balance.」

　So, it required no less than 600 years for Japan to recognize that the Chinese were ridiculing them as submissive crouching dwarves who squat like animals or women…and, after almost two millennia, the Japanese still do not recognize that they were also referred to as the「land of imbeciles.」Is it any wonder why today that the Chinese and Japanese rank number one in the world as the country pair having the most animosity for one another? It's not only the Japanese—the Koreans are mocked in the same manner, and at times the Chinese lampoon themselves, too. Note that SUNRISE, MORNING as an element is generally depicted with「sun amidst one top plant and one bottom plant」while「sunset」(莫) is generally depicted with「sun amidst two top plants and two bottom plants」almost as if some plant growth occurred during the daylight portion since sunrise….
　「Screwing」「tonguing mouth」and「screwing again」to depict bonobo-human activities in the MORNING, in particular by someone not inclined to start work early, an IGNORAMUS.
