speak and write english the right way

There are different ways to greet people:

    Greeting means welcoming someone with particular words or a particular action.

    When meeting people formally for the first time, we greet by shaking hands and saying "How do you do?" or "Pleased to meet you."

    "How do you do?" isn't really a question, it just means "Hello".

    When young people meet informally they sometimes greet and say "Give me five!" and slap their hands together (high five).

    Generally we do not greet by shaking hands with people we know well. We greet by just saying 'hi' or 'hello'
