As a fish genetic breeder, he has long been dedicated to the research of developmental genetics and biotechnology related to fish genetic breeding, and tirelessly strives to achieve the freedom of Chinese people to eat fish. For over 40 years, he has led a team to cultivate 4 new high-quality aquatic products and has been granted more than 10 invention patents, providing more delicious food for the Chinese people. Recently, the story of Academician Gui Jianfang, a researcher at the Institute of Hydrobiology, Chinese Academy of Sciences, has attracted much attention, and his brilliant spirit of scientist is even more thought-provoking. China needs to be strong, and the Chinese people must have strong technology to live a better life. Currently, global technological innovation has entered an unprecedented period of activity, and the impact of technology on national destiny, economic and social development, and people's livelihoods is unprecedented in scope and depth. Since the establishment of the People's Republic of China, it is precisely because millions of scientists and technology workers have worked hard to innovate and silently cultivate that China has leapt from a country with a very weak scientific and technological foundation to a technology powerhouse, successfully achieving historic leaps in China's scientific and technological strength. In the current era of accelerating the development of new productive forces and solidly promoting high-quality development, vigorously promoting the spirit of scientists is of great significance for forming a strong atmosphere of advocating innovation, respecting talents, and loving science in the whole society, further stimulating the driving force of scientific and technological progress, and seeking a happy life for the people. Promote the spirit of scientists and prioritize motivating innovation. Innovation is the primary driving force for development. In the field of scientific research, innovation often starts with questioning, without blindly believing or blindly following. In Academician Gui Jianfang's research, if we follow the perspective of foreign scholars, it is likely to enter a dead end of research. But through bold assumptions and careful verification, he and his team traveled across the great rivers and lakes of our country, collecting more than 5000 samples of crucian carp, systematically studying the genetic basis and reproductive mechanism of silver crucian carp, revealing for the first time the unique multiple reproductive mode of silver crucian carp, finding ways to improve varieties, and achieving a major breakthrough in scientific research. Promote the spirit of scientists and make benefiting the people the key. Research should be implemented in practice, which means focusing on the national economy and people's livelihoods. Academician Gui Jianfang's research may seem like a small crucian carp, but in reality, his discoveries and research results have laid a theoretical foundation for the precise cultivation of excellent varieties of silver crucian carp in the system. The new varieties introduced have achieved a significant increase in yield, allowing the people to go from "eating well" to further "eating well", making contributions to the stable production and supply of "vegetable baskets". Looking back at history, generation after generation of science and technology workers have a broad vision of "the greatness of the country", focusing on people's livelihood, writing papers on the land of the motherland, leveraging their professional expertise to serve the country and benefit people's livelihoods, and allowing precious spirits and traditions to be accumulated and inherited. Promote the spirit of scientists and cultivate a pragmatic style of seeking truth. Technological innovation is not achieved overnight, and behind it often comes a lot of unknown hardships. The acquisition of major research results often requires more than a decade, even decades, and generations of continuous struggle. Generation after generation of technology workers have made seeking truth and pragmatism their lifelong pursuit, and have repeatedly honed a pragmatic and rigorous academic style in scientific research. The vast number of scientific researchers are determined to sit on the bench for ten years, and adhere to the perseverance of "grinding a sword for ten years". They are focused and dedicated to scientific research, and strive to achieve success without relying on themselves
