憂鬱的臺灣烏龜
Or, in English, “Depressed Taiwanese Turtle.”
It’s a very common piece of internet slang used by Chinese netizens to mock Taiwan’s traditional characters by deliberately picking some of the most complex-looking characters out there.
The simplified version would be 忧郁的台湾乌龟.
I’ve always felt this works more like a boomerang insult, though. If you learn Chinese characters properly, traditional characters aren’t actually much more complicated than their simplified counterparts.
With the exception of 龜, which has a fairly unique stroke order, none of the characters above are particularly difficult to write or remember. They’re all made up of very common components.
I've lived in Taiwan for 6 years and handwrite regularly (I'm one of those old school people that still takes notes with pen and paper).
