IELTS is set into three sections.
Part 1 is generally something about you, where you are from, do you like something, what do you think of something etc.
So you can prepare before the test to answer some of these questions. Of course you can’t prepare for all things, as the examiner may throw in a few curve balls (tricky). This exchange of questions is ing to be about 5 minutes.
When asked a question, for example, “Where is your hometown?” you might answer“Shanghai” This is correct but hardly a worthy answer that will convince the examiner to expect a lot from you.
Give the place and then say something about it as this shows you can engage in a conversation and not just regurgitate (give) facts and names. Maybe say something about the city, location, size, the fact you might not know much about it because you left at a young age.
“I come from China’s largest city Shanghai, on the coast; do you know the area of Minhang in Shanghai? That is the part of Shanghai I was born”
A bit more than just one word.
Chances are you will get a follow up question as this is a conversation and in conversations you garner (get) information from those you are talking too.
“Can you describe… to me” or “How has the city changed” or “What do you like/don’t like… about…” or “What are the people like” or "Who lives in your neighbourhood" or"Where do you buy groceries"
Answer how you feel. This isn’t a test on facts, if you lie all the way through then be prepared as lying or non-truths can come back to haunt you.
“I come from the state of Nanjing in Beijing, next to India” Completely wrong but no one is taking notes on that. You will get a follow up question about it so chances are you will have todig yourself out of that hole (talk your way out of a lie). The truth is often easier to talk about.
