A lot of kanji are lining up.
However, similar kanji are mixed in it.

Let's choose that kanji.
It seems that kanji seems to fall apart within it,
It will be a so-called "konpaku" state which can not be said anything from the middle.

In other words, you fall into the "Gestalt collapse".

As a result of continuing to write the same letters for memorization during test study,
"Have you made it this character?"

That's it.

Without causing Gestalt collapse in your brain,
Can you continue to recognize it?
