As the People’s Republic of China celebrated the 60th birthday, the success of the language was one of the mainly things to do be proud of. China is a country of many region (地区) and many dialects (方言). It was difficult for people to communicate with each other. Mandarin (Putonghua), the language commonly spoken around Beijing, was encouraged as national language. In 1982, the government promoted the use of Putonghua throughout the country. It was obligatory (义不容辞的,必须履行的) to speak Putonghua in schools, in other institution (机构) , on radios, TVs and in films.
The policy (方针,政策) has been wonderfully successfully. And it’s not just successful in mainland China but in Chinese communities around the world.
China celebrated its 60th birthday, so enjoy it: Be proud of our country and be proud of our language.
