The composition of the letter to Yuan Longping.

Grandpa Yuan: I am writing to you when Vientiane is updated in the spring. My heart is also full of green and hope. Know that your name is in the book: Academician of China Academy of Engineering, a famous hybrid rice expert, is praised as the father of hybrid rice by the world. The first national special invention award in China won the international prize 1 1 time, and the famous brand value was 1000 billion yuan. I saw your figure on TV: 74 years old, you have to put on paddy boots and ride a motorcycle to have a look in the paddy field. You are a scientist with muddy thoughts on your legs, as simple as a farmer. Since 1979, eight or nine cars have been damaged due to running around all the year round. Understand your achievements from the figures: you have successfully cultivated hybrid rice. From 1976 to 1999, more than 3.5 billion mu has been planted nationwide, with an increase of 350 billion kg. It accounts for 50% of the national rice planting area, with an average increase of 20%, accounting for nearly 60% of the total rice output. The annual increase in rice can feed 60 million people. Some people regard hybrid rice as the fifth great invention dedicated by the Chinese nation to mankind. Bread is the pillar of life. Especially in China, a developing country with a large population, for thousands of years, food is survival, national stability. To stay away from poverty, the first thing is to stay away from hunger. In order to stay away from hunger, many people left countless tears and sadness. Looking around the world, hunger and poverty go hand in hand, and the picture of famous vultures waiting to devour hungry babies stung the eyes of the whole world. In the hearts of the poor, you are the holy water of the Bodhisattva and the gospel of God. Nowadays, the problems of agriculture, countryside and farmers have become a century-long problem. You said that we farmers should have this obligation to help farmers increase production and improve their lives. You bred with wisdom, irrigated with sweat, watched with conscience, and silently contributed to increasing farmers' production and income. The heavy grain has bent the rice stalks in the north and south of the river, and your spirit has been lifted up in the hearts of hundreds of millions of farmers. You have given China a solution to poverty and hunger, gained precious time, and guided the people to a well-fed world. Einstein said that science has no nationality, but scientists have nationality. Honor and wealth have not changed your true colors. You have been paying attention to the land and people with childlike innocence. Faced with the grim situation of urban expansion, shrinking arable land and increasing population, you always take "whether China people can feed themselves" as a warning and self-encouragement, and take increasing output per unit area and preventing hunger as a solemn commitment to the great motherland. A nation without heroes is the most pitiful nation in the world, while a nation with heroes who do not know how to respect, love and admire is a hopeless slave country. Grandpa Yuan Longping, as a middle school student in a black land and a descendant of an immigrant family, I sincerely thank you. My mother was born in the 1960s when material resources were scarce. In her memory, hunger accompanied her through a difficult childhood. Without your scientific research, she might be threatened with death. I sincerely wish you good health and vigorous spirits, especially those with scapulohumeral periarthritis, and you must pay attention to cold protection and avoid overwork; I also want to promise you, with the motherland in mind, to make progress, to do things well, to be a good person, and to contribute to the prosperity of the country and the rejuvenation of the nation. In 2004, due to physical reasons, you didn't attend CCTV's "Top Ten People Who Moved China" award ceremony. I want to design an award for "Great China People" for you, and announce the award speech: a 74-year-old scientist, his appearance is like 84 years old, his energy is like 34 years old, and his mentality is like 14 years old. He contributed millions of private property to scientific research, saved millions of lives for poor families and contributed hundreds of millions of wealth to all mankind. He is the greatest China man in my heart.
