Currently, Yunnan Province of our country is suffering from a once-in-60-years major drought, without rain for months. Rivers and ponds have dried up, and so have the wells. More than 6 million people are experiencing water shortage, and 30 million mu of farmland has been affected. What is more terrible is that, according to predictions by meteorological experts, it is possible that the drought in Yunnan will continue until the rainy season arrives in May.
