Did China need yonth-leader?

In modern competitive world, the energetic and knowledgable leaders are more and more important to companies, orgnizations and countries. However,the opinions refer to this topic are vary from individual to individual.Some people maintain that elder leaders have a great deal of experience and cool head which can do business in a moderate way. Others argue that yonth-leaders are more enthusiastic and energetic on  their jobs. And the most important point is the spirit of innovation and adventure. We know in such a rapid developing globle market and society, leaders must keep in step with the times. Therefore,I argue that China do need yonth-leader to develop our economy.   

Throughout its history,especially in China government, we found that the leadership's age had decreased gradually. In development countries, such as USA and Russia,we see the presidents are younger than China's.I really admire Bush's force and Putin's ability. Especially Putin was a spy before he run for the president. The current Chinese chairman and premier’s age is far more yonth then before, and their experience and ability is suitable for charging our country. We not only need stable social order but developming economy. So after watching premier Wen answer the questions on press comference, I am fully aware his foresight.
