In the face of the rapidly changing world and China, if you stick to the rules, have rigid thinking and have no courage to innovate in theory, you can't scientifically answer the questions of China, the world, the people and the times. Not only will the cause of the party and the country fail to advance, but Marxism will also lose its vitality and persuasiveness.

Contemporary China is experiencing the most grand and unique practical innovation in human history. The task of reform, development and stability is arduous, the challenges of contradictions and risks are numerous, the test of governing the country is unprecedented, and the world has undergone a great change in a hundred years. A large number of theoretical and practical topics that need to be answered urgently are put forward.

The world today is experiencing a great change that has never happened in a century. World multipolarization, economic globalization, social informatization and cultural diversity have developed in depth, the global governance system and international order have been accelerated, emerging market countries and developing countries have risen rapidly, and the international power balance has become more balanced. The destinies of people all over the world have never been so closely linked as today.

Instability and uncertainty are prominent, world economic growth is weak, trade protectionism, isolationism and populism are on the rise, polarization between the rich and the poor is becoming increasingly serious, regional hot issues are emerging one after another, and non-traditional security threats such as terrorism, cyber security, major infectious diseases and climate change continue to spread. What happened to the world? What should I do? In such great development, change and adjustment.
