What are the advantages of E-education, Professor Gu? There are at least four advantages. First, with access to the Internet, students can overcome barriers of space and time. For example, we can make educational resources in Beijing available to students in Xinjiang. Second is the easy access. For example, we can put multimedia resources libraries on the Internet and students can have access to these libraries just by clicking the mouse. The third advantage is the optimization of resources. For example, we can tape the lectures given by very prominent professors and broadcast them live in China and even in the entire world through the Internet. Because of these three advantages, there is another big advantage, that is, the Internet technology makes mass education possible. As you know, it is simply impossible for the whole population to receive education on campuses. It is impossible economically or otherwise. And this is where the greatest advantage of E-education lies. It offers mass education and education for lifetime. Can you briefly tell us the history of China's E-education, Professor Gu?
