Hi there! چگونه is rather literary (too formal) whereas چطور is used in daily conversations. it sounds really weird to a native speaker's ears if someone says: حالت چگونه است. you might find it in written discourses or in dramas for instance: چگونه می توان گریخت. how can one escape? چگونه فرزندم را رها کنم how can I forsake my child

Many thanks Hamed !

Hi, You can use both of them and native Persian speakers will get your meaning. But چگونه؟ is not common at all. However, we sometimes say to our friends چگونه‌ای؟ just for fun.

Thank you so much. Indeed like in French or in English many things can be said but it would look funny to write it, except in cartoons etc... But you are right it is funny sometimes to use formal words to see people reaction :)

Actually I sometimes tell my friends: چگونه ای؟ Instead of saying چطوری؟ But it's funny, they first laugh and then answer. Some structures must be learned by heart Oliver, for example you say 'what's up?' But you never say 'what's above?' Well, also چگونه belongs to written style of Persian . except for news or formal discussions, we never say چگونه but we write it. چطور can be always used instead of چگونه when speaking.
