I’d like to give you a piece of advice about ... people you see for the first time. When you meet a person you should shake ... with him or her. It’s polite to greet the person “How do you do” or “ ... ”, you may also say “Hello”. It’s not a good idea to start asking the person about his/her ... . You should first introduce yourself. After that you may ask the person about his/her name, job and ... but don’t ask a person about his/her ... as it’s not polite!
