Translation:The bread is small.
For me, the trick is that whenever I pronounce 빵, I sort of exhale sharply while it's being pronounced, while 방 has sound like how 'b' usually sounds when you pronounce 'book' (if that makes sense lol)
I keep on watching the variety show 'Men on a Mission' to train my ears for Korean words (and I also take note of definitions of words I constantly hear whenever I listen to Kpop or watch a Kdrama)
I hope you get it too! Fighting!
