Global Times reports instructions for TV and radio hosts to use more “proper Putonghua”:
The State General Administration of Press, Publication, Radio, Film and Television of China issued a notice, saying that presenters should take the lead in promoting the use of standard Putonghua, in an effort to enhance the soft power of Chinese culture.
They are not allowed to “imitate” the pronunciation of characteristic dialects. Mixing foreign languages, slang, and some cyber phrases, which could be “harmful” to the standard use of language, should also be prohibited.
[…] According to a survey conducted by sina.com.cn on Sunday, over 66 percent of 11,151 respondents voted against the administration’s move, with many saying that the move showed little respect toward various cultures in different places around China. [Source]
