Before their sending lanterns into the sky, they wrote their wishes on those lanterns.
..... I want to know why the sentence is right, because the grammar is quite strange to me.

Hello Jean Heloise - welcome to the forum.
Yours is an odd sentence, I agree.
And I do not think that it is "right", as you say.
"Before sending their lanterns into the sky, they wrote wishes on them" is a much better sentence.
Just because something is written does not make it correct.

This is one of our selection in our junior high school exam.
I thought that it was really weird and I chose the sentence as the wrong answer.(we were choosing the wrong usage)
But our teacher said that the sentence is right.
so I really don't know what in the name of earth is he doing
and thanks for your help

What was the answer your teacher said was wrong? It's possible the answer key was wrong.
