Innovation is the soul of a nation's progress and an inexhaustible motive force for the country's prosperity. Our Chinese nation has always been hardworking, brave, intelligent and creative. Teenagers are the pillars of the future of the motherland, and their scientific and technological quality determines the development of the motherland and the future of the nation. To keep pace with the development of science and technology in the world today, we must implement the strategy of rejuvenating the country through science and education for a long time, with science and technology as the guide, education as the basis and talents as the key. Under this initiative, the National Youth Science and Technology Innovation Competition is a national science competition for scientific innovation and scientific research projects for young people with a history of more than 20 years, and it is one of the largest and highest-level national youth science and technology education activities for all primary and secondary school students in China. Over the years, it has played an important role in enlightening young people's scientific minds, developing innovative thinking, improving the quality of science and technology, cultivating good feelings of loving the motherland, nature and science, establishing scientific ideas, feeling the spirit of science, cultivating future workers with certain scientific and technological skills and cross-century scientific and technological talents needed by modernization, and has become an annual festival for young people's scientific and technological activities. Dear young friends, as you know, those who stand out from the storm in today's society are all people with innovative consciousness, innovative spirit and innovative ability. Only innovative talents with comprehensive quality are the masters of the future world. I hope you will continue to March into the vast and mysterious field of science, bravely climb the peak of science, and let the innovative wisdom shine in the process of continuous progress.
