"Three sentences and a half rhyme is very strict. Specifically, the first, second and fourth sentences must rhyme, "rhyme to the end"

So your arrangement is wrong. If it is three and a half sentences, the third sentence "should be beautiful":

The math teacher has a good figure, the English teacher is very kind and the Chinese teacher is twice as beautiful. It's all treasures!

But the "amazing" upstairs is also good.
