LANZHOU -- Chinese Vice Premier Wang Yang has asked officials to enhance preciseness in poverty alleviation by collecting accurate information of impoverished people.

The poor people should be clearly identified and their information be archived so that the government can help them in an accurate way, said Wang during a recent trip to Northwest China's Gansu province.

At the end of 2014, China had 70 million people in the countryside living below the nation's poverty line of 2,300 yuan (about $354) in annual income.
