"After going to school"

Translation: 학교에 간 후에

[viswarkarman]

Why not: 학교에 가기 후에

[sonnert]

shouldnt it be 가는 or is that not a thing?

[wintertriangles]

가는 is currently going. 간 is "already went." Whenever using 후에 after a verb you'd always use ㄴ/은 to follow it.

[UltimetaSy]

는 = is
ㄹ = will
ㄴ = has

[KVRP4]

「학교에 간뒤」、the word「후(後)」can be replaced to「뒤(native korean)」

There's also 다음. And I read on a blog that 후 is pretty much formal compared to the other words, being used in very formal situations as well as in songs or novels. While 뒤 and 다음 are used in casual conversation, messages and such.

That's right!! Thank you for the contribution.

후에sounds like후회(regret) isn't it?

[GeraldMath4]

I don't hear the /h/ or the lip-rounding.

Regret after going to school? Lol
I think you forgot your homework
