The four articles written in this book are intended to familiarize readers with the three major conflicts held on the philosophical front of "New China" established in 1949. These articles, written by the "Revolutionary Mass Criticism Writing Group" under the Central Committee of the Communist Party of China, were first printed in "Renmin Ribao" (People's Daily), "Hongqi" (Red Flag) and "Guangming Ribao" (Kwangming Daily).
