Recently, "Awesome my country!" This online buzzword has been screened one after another. Chinese people use this catchword to express their joy and excitement about the recent breakthrough in science and technology in China. The first flight of C919, the launch of the first domestic aircraft carrier, the delivery and refueling of "Express Brother" Tianzhou-1 in space, the advent of quantum computers, and the successful trial mining of combustible ice ... A series of major scientific and technological achievements in China appeared frequently. If we broaden our horizons, the list of China's major innovations in recent years will be even longer: "Five-hundred-meter Aperture Spherical Radio Telescope (FAST)", "Mozi", "Jiaolong" and Tiangong No.2. When the progress bar of independent innovation is refreshed again and again, China people's scientific and technological self-confidence is also ignited again and again. "Awesome, my country!" China people's national self-confidence and pride came into being. Scientific and technological dreams, such as flying dreams, flying dreams and quantum computing dreams, are all important parts of the dream of strengthening the country. We can see that the older generation of scientists have worked hard to make China people have many dream stories that can go down in history, and a large number of high-level scientific and technological achievements such as "two bombs and one satellite", "synthetic bovine insulin", "hybrid rice" and "artemisinin for malaria" have made China people establish scientific and technological confidence. We have also seen that the new generation has made great efforts and embarked on a road of self-reliance and independent innovation. The scientific and technological progress such as manned space flight, lunar exploration, and "Jiaolong" sea exploration has made China people more confident in science and technology. The continuous breakthrough in the field of science and technology bears witness to the fearless spirit of China people who are willing to contribute and dare to tackle key problems. No matter how the scientific research environment changes, the will of China researchers to strive for self-improvement and independent innovation has never changed. Hard work will be rewarded. Today, China is changing from a "runner" to a "parallel walker" and a "leader" in some scientific and technological fields. More facts tell us that China people attach importance to innovation, dare to innovate and are good at it. In 215, China accepted more than one million patent applications, ranking first in the world; In recent years, the number of high-quality papers in China has soared; Among the 2,5 enterprises with the largest R&D investment in the world, China accounts for more than 3 ... While establishing "scientific and technological self-confidence", we should also refuse to be blind and arrogant. In the face of the new situation of increasingly fierce international scientific and technological development, we should keep a clear head: many key core technologies are still in the hands of others, the original innovation ability still needs to be improved, some unreasonable scientific and technological systems and mechanisms still restrict the release of innovation vitality, and many enterprises still need to enhance their innovation awareness and R&D ability ... To make up for shortcomings and dare to touch major scientific and technological propositions is becoming an important proposition in China's scientific research field in the new era. The unreachable space and deep seabed have been turned into a reality by China people with wisdom and sweat. But China people's dream will not stop there, but move towards deeper, farther, higher and wider fields. My country will be even more powerful!
