On the occasion of the seventh National Science and Technology Workers' Day, many science and technology workers are still busy, either sending technology to the countryside, assisting rural revitalization, or entering factories and workshops to inquire about enterprise innovation, or targeting major national needs and accelerating technological breakthroughs. They are eager to meet the needs of the masses and solve the difficulties of development, celebrating their holidays with struggle. Scientific research should not only pursue knowledge and truth, but also serve economic and social development and the general public. Professor Li Baoguo from Hebei Agricultural University took root at the grassroots level for over 200 days each year during his lifetime, turning 1.4 million acres of barren mountains green and leading 100000 farmers to lift themselves out of poverty and become rich; Professor Lin Zhanzhi from Fujian A&F University has been working hard on the front lines of scientific research and poverty alleviation, helping millions of farmers grow mushrooms to lift themselves out of poverty... The needs and calls of the people are the voice of the times for technological progress and innovation. Writing papers on the land of our country and applying scientific and technological achievements to the great cause of modernization is an important responsibility that science and technology workers should shoulder and an inherent requirement for growth and success. Only innovators advance, only innovators are strong, and only innovators win. The 20th National Congress of the Communist Party of China sounded the clarion call for a new journey of progress, and we need to build a technological powerhouse more than ever before in history. With the lofty ambition of serving the country through technology and unleashing a powerful engine of technological innovation, the "flower of technology" will become more brilliant in the field of hope. The vast number of scientific and technological workers will surely write wonderful lives on the land of our country, and will also contribute more to the self-reliance and self-improvement of high-level technology.
