The radical middle and the kanji middle are both the same. So if you know one, you know the other.

To remember the reading for this kanji, we use the word Chewbacca to pull up ちゅう in our memory.

If you remember back to the radical 中, a stick was stuck in the middle of the mouth of something. Let's say it was your mouth, and when you look up to see who did it, there stands Chewbacca. He's even doing his Chewbacca yell. And it isn't a stick in your mouth, it's an arrow from his bowcaster. It just so happens Chewbacca's bowcaster looks just like this kanji too. Go figure.
