The very reason for China to be able to restore unity after each period of split-up over the past millennia is the people’s deep awareness of their cultural identity. The book examines the ideas, principles and policies concerning a unified dynasty in Chinese history, and on this basis explores how China emerged and grew as a unified nation. The concept of “Great Unity” is so deeply embedded in the Chinese culture that its cultural implications and creative evolution are clearly manifested in the socialist core values, the principle of cultural exchanges, the regional ethnic autonomy policy, a global community of shared future and many other important ideas China advocates today.
