Quote:Young and old residents of the Chinese metropolis of Wuhan were advised to stay indoors on Monday after a thick haze blanketed the city of nine million people, official media said.
Described by residents as opaque with yellowish and greenish tinges, the fug descended suddenly in the morning, prompting people to rush to put on face masks, witnesses told AFP.
Xinhua said straw burning was the cause and denied there had been any industrial accidents in or near Wuhan, after Internet rumours suggested there had been an explosion at a chemical complex northeast of the city.
"I looked out of the window of my office and I could not believe my eyes," said resident Li Yunzhong.
"At first I thought it was going to rain. In 31 years in Wuhan I have never known anything like it. We are very worried because we do not know what it is."
They blamed farmers burning hay?
Did they burn the entire world's supply of hay all at once?
