From Zài jiàn and Míng tiān jiàn, we can see the pattern, which is jiàn (to see) is at the end of the expressions. 

So here is a challenge for you:

If yí huìr means later, how do we say "See you later”?

"See you later" is yí huìr jiàn.

Please play the sound below, listen to the pronunciation, and repeat to practice!
