Over 200 sci-tech workers from various fields attended a symposium to celebrate the second China's National Science and Technology Workers' Day on May 30.

They were encouraged to improve China's sci-tech quality and cooperate more in global S&T on the symposium.

Guo Cuiping, a researcher with Hebei Agricultural University, has been working on rural poverty alleviation through science and technology.

"The largest problem currently is that general agricultural science and technology cannot reach many farmers," said Guo. "If farmers don't have the knowledge, then the economic value of their harvests will not meet their expectations."

Addressing the problem requires government's efforts to cultivate more and more sci-tech workers interested in agriculture development, Guo said.
