  3. Do you know who Yuan Longping is ?

  A brief introduction:

  Yuan Longping is known as China’s "father of hybrid rice". It’s said that in China, we eat depending on "Two Ping" ---- Deng Xiaoping, who made the policy of System of Production Responsibility, & Yuan Longping, who invented hybrid rice.

  Yuan Longping, who was born in September, 1930, graduated from Agriculture Department in Southwest Agricultural Institute. He has been working on agriculture education & the research into hybrid rice since he left the institute.

  In the 1960s, when China was suffering from serious famine, he came up with the idea of hybrid rice, which has a high yield ( or output). Ten years later, he succeeded in inventing a new species that produced a 20 percent higher yield than common types of rice.

  Yuan devoted himself to the research into agriculture, & was honored by UNESCO & FAO(联合国教科文组织)。 Although he is 74 years old, he is still working on the research into agriculture.
