"Is Seoul overcrowded?"

Translation: 서울은 혼잡해?

[Okawoa]

서울은 혼잡합니까?

[CF00l]

서울은 混雜해요

[derLudo]

Why is it trying to correct 복잡해요 to 혼잡해요? I thought both could mean 'to be crowded'?

[GirishDedh]

"복잡해요" is only "Crowded" whereas "흔잡해요" means "Overcrowded". That's the difference.

[jaisaige]

난 몰라요
