so what's the difference between 에 관하다 and 에 대하다?
에 관하다 is just more polite but both have the same meaning
I had the same question.
Can someone tell me why 동물들에 is wrong?
Because the particle 들 is used only to people plural maker. Hope it helped :)
Why we can't use 관하여 instead 관한?!
I think it's because 관하여 is for verbs
