I think you want to know usage of "How" during speaking english, right? We use "How" to ask about things that change – for example, people’s health and moods. We often use how to ask about people’s reactions to their experiences. Ex-‘How was the film?’ ‘Not bad.’ ‘How is your new job?’ ‘Quite interesting.’

not how，what you use。。。。。

I'm not sure what your asking..."How" is a word that we use when speaking English and most commonly used when asking a question.
