War against poverty fought in farmlands

Rather than having an office on campus, Professor Li Bingzhi's classroom is on a stretch of farmland.

Each year, Li, a professor at Northwest Agriculture and Forest University in Shaanxi province, spends nearly 300 days in the orchards of isolated Qianyang county.

"I teach farmers about the latest cultivation technology, face to face. It is our duty to help farmers out of poverty," Li said.
