I love mysteries... Here's what I found out:
First, I drew the most simple ideogram, the third one from the orange sign. Google translate has a tool that allows you to draw the word and it gives you suggestions of what you tried to drew. Then, google suggested "soldier" and I noticed it was using the fourth ideogram too, in combination with the one I drew. 2 in 1, lucky me!
Well, if the last half means "soldiers", maybe the first means... super? Super...soldiers? Superfighters? Yes, according to Google. "Supersoldiers" was the literal translation it gave me.
What about the other neon sign? I tried drawing the rest of the ideograms, and this is what I got.
Chinese language combines ideas and concepts to form new words. If I isolate each ideogram, google suggests me a few possible meanings, if I combine the ideograms with some other ones.
(orange neon sign)
超 - exceed, surpass, transcend
級 - level, grade, rank
士 - scholar, soldier, warrior,
兵 - soldier, troops, army
translation - soldiers who have "surpassed rank", high-rank soldiers, "superfighters"?
(pink neon sign)
強 - emphasize, mandatory, force
列 - columns, row, sort, series
?
本 - this, root, origin, source
translation - mandatory row... origin... uhh... strong columns...? I have no idea.
I tried drawing all of the ideograms, but I couldn't draw the third one from the pink neon sign. So the mystery is still on...
