Cheng Gong's Book entitled Paul Levinson's Media Evolutionary Theory

This is the cover of Cheng Gong's book, just published in China, (English translation): "Media Competition for Human Selection, Survival of the Fittest: Paul Levinson's Media Evolutionary Theory" - as far as I know, the first book published anywhere on Planet Earth devoted entirely to my work. The Preface that Cheng Yong asked me to write follows (it appears in the book both in my original English, which you can see below, and in Chinese translation).
