Thanks to their toiling day.

Yuan Longping, known as the "father of hybrid rice", was one of China's most famous scientists. Yet, he considered himself a farmer because he continually worked the land in his research. Indeed, his slim but strong body was just like that of millions of Chinese farmers, to whom he had devoted his life.
Why did Yuan Longping consider himself a farmer

To tackle this crisis, he chose to study agriculture and received an education at Southwest Agricultural College in Chongqing.

After graduating in 1953, he worked as a researcher.Yuan Longping realised that larger fields were not the solution.Instead,farmers needed to boost yields in the fields they had. How this could be done was a challenging question at the time.Yuan was convinced that the answer could be found in the creation of hybrid rice.A hybrid is a cross between two or more varieties of a species. One characteristic of hybrids is that they usually attain a higher yield than conventional crops. However, whether it was possible to develop a hybrid of self pollinating plants such as rice was a matter of great debate.The common assumption then was that it could not be done. Through intense effort, Yuan overcame enormous technical difficulties to develop the first hybrid rice that could be used for farming in 1974. This hybrid enabled farmers to expand their output greatly.
Yuan conducted research and developed hybrid rice.

What impresses people most about Yuan Longping is his ongoing
ability to fulfil his dreams. Long ago, he envisioned rice plants as tall as sorghum, with each ear of rice as big as a broom, and each grain of
rice as huge as a peanut. He succeeded in producing a kind of
rice that could feed more people at home and abroad. His latest vision
for “seawater rice” has also become a reality, and potentially opened
up nearly one million square kilometres of salty land in China for rice
production. Despite his advanced years, Yuan Longping is still young at heart and full of vision, and everyone is waiting to see what he will
dream up next.
Yuan worked hard to fulfill his dreams.
