来 and 学, from the original example, are both simplified characters (the traditionals being 來 and 學). I was a little bemused to see them in an example of Japanese text, but it turns out they are the common Japanese characters as well. Japanese has its own set of simplifications ( <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Shinjitai" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Shinjitai</a> ), often overlapping with the Maoist simplifications.<p>In a different pattern, mainland China simplified 龍 to 龙 while Japan simplified it to 竜. Despite being a &quot;simplified&quot; form, 竜 is actually the oldest of those three characters.<p>&gt;&gt; For those who don&#x27;t know Japanese, only following my rule, can you identify the Japanese characters in the sentence above?<p>I would technically meet that requirement, but knowledge of Chinese makes the question pretty easy regardless of knowing Japanese. ;)
