Sick people should stay home and not to go work. This is especially the case if you happen to be one of the mainland's star news anchors, whose broadcasts are potentially seen by more than a billion people. Popular CCTV newsreader Kang Hui was recently spotted with a runny nose during a midday broadcast. But the valiant anchor continued to read the news for several minutes while millions of viewers watched, in fascination and horror, as the droplet slowly migrated from his nose to his upper lip. The video clip is now one of the most widely circulated on the mainland internet this week. Anchors from the top electronic mouthpiece of the central government are well-trained and groomed. Picked from thousands of candidates for their looks, poise and language ability, mainland newscasters are a media elite, well-paid and respected. And in their highly demanding job, one of their instructions must obviously be never to be seen wiping or blowing their nose in front of the camera.
