     Tigers used to live in many places in China. But now, you have more chance of seeing US golfing

champion Tiger Woods than a South China tiger out of a zoo or reserve (自然保护区). Scientists think

there might be none left in the wild. But it seems that Zhou Zhenlong, a 42-year-old farmer from Zhenping

County (稹坪县), Shanxi Province, got lucky.

     He says that he has taken a photo of one South China tiger, which he put on the Internet on October

12, 2007. It shows a tiger lying in bushes. But some think that the picture may not be real. They think the

farmer may be trying to make some money.

     Although the South China tiger is a dangerous animal, people want to believe that it still lives in the

Qinling Mountain area of Zhenping County.

     In the early 1950s, there were still 4000 left. Some forestry workers (森林管理员) believe that 30 - 40

are living there, The fanners there say that they have heard the roars of tigers and seen their footprints. The

forestry department has never allowed hunting around the mountain in the county. They want to let the king

of the woods live with us forever.
