Peoples press thoughts, proletarian partys newspaper and political propaganda ideology constitute the basic contents of Marx and Engelss political communication thought. Marx and Engels used the academic discourse of modern political communication to understand the phenomenon of political communication. They scientifically expounded the basic principles of modern political communication, and revealed the basic relations among political organizations, media and people in the process of generation of political communication. This series of thoughts not only analyzes the theoretical basis of modern political communication, but also points out the practical path of proletarian political communication. These ideas have a theoretical continuity in socialist China. We should apply the basic principles of Marx and Engelss political communication to the political communication process of Xi Jinpings thoughts of socialism with Chinese characteristics in the new era, so as to promote the thought of socialism with Chinese characteristics in the new era to be deeply rooted in the hearts of the people. This is the fundamental direction for current political communication.
