The challenge of living a big ci

    As we all konwn,many of people want to make a living ,so they start to get away from their hometown.However,I don't think so.

    First,traffic jam is very common in big city,and it is very troublesome.Because of this,they have to get up earlier to avoid it,but,it is also disavoidable.Addionally,pollution is also a serious problem there,all kinds ofpollution.Itisveryharmful.Besides,there are other factors to affect my impression of big city.

    To sum up,in my opinion,advantages is more than disadvantages.So I think that it is a very big challenge.
