As the Chinese nation is in the process of its rejuvenation, we are inspired to compile a volume of A History of Confucianism . Any nation's rejuvenation is bound to pump up its national cultural fever. Since Confucianism has always been the mainstream culture in China's history, influencing every aspect of Chinese social life, its rejuvenation is inevitably correlated with the Chinese national rejuvenation. In the very beginning, Confucius inherited the culture of the Xia, Shang and Zhou Dynasties, which was deemed as the root of the Chinese nation's development. If for some reasons this root is cut off then there will be no hope for its rejuvenation.
