With the development of economy, the urban development is becoming faster and faster. Thus, more and more old houses are pulled down to rebuild new ones. Someone think that it's right to pull down the old buildings in the way, while others argue that the old houses and buildings are precious and we should protect them. Well,we found ourselves caught in a dilemma whether we should reach for rapid urbanization or the preservation of the ancient buildings. The controversial issue is often brought into public focus. Views on the issue in question vary from person to person. As for me, I think we should hold different opinions in different situation.
