    Living in the information time, we are faced with tons of news about our county and society every day. But what is true and what is false? There is a group of people whose job is to offer an official (官方的) voice and form a bridge between governments, the public and the media (媒体). These people are news spokespersons.

Spokespersons usual host news conference (会议), where they explain policies (政策) and answer questions from the media. According to Foreign Ministry spokesperson Geng Shuang, a news spokesperson is “a window into our county for the media, especially for the foreign media.”

To achieve this, news spokespersons are often experts in some fields. This way, they can clearly express these fields to the public.

For example, Wang Hui, the spokesperson for the Beijing government during the 2008 Olympics, was once a senior editor (编辑) at the Beijing TV station. She has lots of knowledge about how the media works. Mao Qun’an, who used to be a spokesperson for the Ministry of Heath, has a master’s degree in medicine. He helped a lot during the SARS illness of 2003.

Spokespersons also need to be able to think quickly. They often have to answer different kinds of questions from the media.

Spokespersons sometimes speak in their own style instead of always using official expressions. Here are a few examples.

It is easier to move a mountain than to shake the PLA. (Wu Qian)

What a waste of money it was for Japan to do so! (Yang Yujun)
