if you have been giving 1 billion dollars

We all know that a billion dollar is a sea of money ,so if I have a billion , what can I do and what should I do must be the questions I think first.

If I have one billion dollar, I not only own my beautiful car and house, but also live the life which I desire to live.

I will stroll about the world to see sights and appreciate different cultures.just like niagara falls and pyramids.

At the same time,I will also set up some law firms which can support poor people to get necessary help like rich one.

If I have one billion ,I will open a housing corporation with all my heart ,i will sell our houses at low price so it can help the homeless people.
