Putting the sparkle back in Erhai Lake

Cleanup mission given manpower and 4.5 billion yuan for projects to improve sewage treatment network around scenic spot. Hou Liqiang and Li Yingqing report from Dali, Yunnan.

For the past two months, Zhao Qiuhua has had to skip dinner most days, and he has rarely been able to get to bed before 2 am. Not that he minds, as he's helping to clean up China's treasured Erhai Lake.

This must-see scenic spot in Yunnan province has been affected by heavy pollution in recent years, yet Zhao and about 140 other government officials are working to restore the lake to how it looked more than five decades ago.
