Baidu founder Li Yanhong is a typical knowledge hero. I admire Li Yanhong very much, especially his business acumen and the ability to grasp the essence of things. As early as 1995, he obtained his first patent for online search, while Larry Page and Sergey Brin, the founders of Google who were computer majors at Stanford University, had just met at that time. Recently, Baidu ranked first in the Wall Street Journal's "innovation in response to customer needs" rating.
