In its quest for linguistic unity in China, the Chinese state is becoming increasingly uncompromising. With an active language policy, they try to get everyone to communicate in national Chinese and write in simplified characters. At the East Asian Museum, we meet the curator Si Han, who tells us why it is so important that all Chinese speak the same language. But a monolingual China is not everyone's dream. Above all in Tibet people protest against politics. Tensin Tsundue tells how people in Tibet are forced to introduce national Chinese as the school language and the only official language. In New York's Chinatown, the Cantonese dialect is still the most viable. Can the Chinese language policy reach this far? We meet Kim who is fighting for the Cantonese to survive.
