「Prick taut」with「repeated, or thousands of screwing, with emissions」or「gonorrhea」described a man limited in schtupping (ejaculation into a birth canal or other attainable orifice) partners, but permitted within a harem of thousands, the first Chinese emperor. Perhaps gonorrhea prevention was the intended dual meaning of the lower element. NATURALIZED FOREIGNER is someone who wanted to be like the Chinese, or to become Chinese, or live as did the emperor. Glyph is purported by scholars to be the source of the word and name of the country「China」after the first emperor to rule all of China used this glyph as a surname.
　According to legend, some scholars have suggested this glyph also depicts HAZELNUTS for their 'herbal' qualities, due to their legendary ability to impart legendary powers of legendary mystic clairvoyance, as does often「repeated, slowly bowed head due to herbs」(or, dimethyltryptamine use), but you'll need to ingest a boatload of the nuts, likely becoming constipated in the process. With all due respect, the elements in other glyphs are「leashed tallywacker, prick and repeated nodding bobbing head with herbs」from which you can draw your own conclusions about Emperor Chin. While his tallywacker may have been leashed, it was a loose one, since his harem is rumored to have drafted thousands of highly-trained virgin concubines.「Leashing his tallywacker」but「repeated thousands of emissions」for use only with virgins helped assure that he did not contract any sexually transmissible diseases, especially those associated with ewes.
　Note that elements as「head bobbing from repeated cannabis use」packs more punch than a handful of filberts. Modern font elements often are explained as bushy plants of grain but those strokes (lower-right) are drawn slightly different, and represent something else that is clearly seen in traditional fonts. Moreover, bushy grain has little to do with being an emperor, if anything at all (…wonder if his eyes were chronically bloodshot, too). In all fairness to Emperor Chin, the lower element is most likely「repeated thousand emissions」as perhaps his annual tally. Let's hope for the sake of his legacy that the elements are not「offering bushy standing grain plants」as scholars suggest, and it does not appear so in traditional fonts.
