1) The word "faced" means with the type of face described.
 For example, Having a round face is called "round-faced"
           Having a sad face is called "sad-faced"
 And the word "faced" is red.
 => So we have "red-faced" ( đỏ mặt / xấu hổ )

2)  We have three letters "aid" and if you put them in order, there are:
 aid -> ( first )
 aid -> ( second )
 aid -> ( third )
 And the arrow points to the first "aid"
 => So we have "first aid" ( sơ cứu/ cấp cứu trước khi bác sĩ đến )

3) Because there are 3 words "cycle"
 => So we have "tricycle" ( xe ba bánh )

4) We have "+" as add
 -> The word we can combine is "addverb" but it has no meaning.  So we leave out a "d" in "add".
 => So we have "adverb" (trạng từ) 

5) We have the letter "I" under the word "stand".
 => So we have "I understand" ( tôi hiểu ) 

6) When we arrange the letters in order from bottom to top ↑ .
 We have the word "wake".  And "wake" always goes with "up".
 => So we have "wake up" ( thức dậy )
