You should be asking the answer to the question of "grain" in the world and enjoying the cool under the grain. The answer is a figure, so the answer is Mr. Yuan Longping.

one rice seed fills all the granaries in the world. Mr. Yuan Longping experienced the famine years and vowed to solve the problem of feeding people in China.

every grain of rice is hard. A porridge and a meal is hard to come by. Nowadays, the problem of eating in China has been solved, but the concept of refusing to waste and cherishing food cannot be lost. The agricultural scientists of Mr. Yuan Longping's generation have struggled all their lives, constantly researching and developing high-yield varieties, only for Chinese people to have enough to eat and eat well. Far away from the famine era, we can't forget their struggle, and we shouldn't let them down.
