    As everyone knows, the global financial crisis resulted from the United States have caused a great effect in the development of the global economy.What shall we do facing the global challenge?

    I quite agree with what the President Hu Jintao said at the 7th ASEM summit.Nothing is more important than confidence.Only if we have confidence and hold together we get through a variety of difficulty.For example, after the terrible earthquake in Sichuan Province, all the Chinese held together and bravely fight against the disaster with great confidence, what won the admiration of the world.

    In my opinion, facing with the present global financial crisis, we should keep calm and not be in a panic.Believe in both our Party and country, then we will certainly live through the crisis.
