China

China is one of the world's most consequential experiments in large-scale national identity. The state officially recognises 56 ethnic groups while promoting a common Chinese national identity through the concept of Zhonghua minzu. Standard Mandarin serves as the shared language of education, administration and national communication. The country combines ancient civilisational continuity with rapid modernisation, and now faces a demographic transition marked by population decline and ageing, making cultural continuity inseparable from family and regional policy.
