Adhering to the strategic basis of independent innovation, Zhu Shaoyi and Li Boxuan recently sent a letter congratulating the 70th anniversary of the founding of the University of National Defense Science and Technology, emphasizing the importance of "accelerating the pace of independent innovation in national defense science and technology, and striving to play an important role in implementing the strategy of building a strong military through science and technology and talent". To study and implement President Xi Jinping's important directive, we must place national defense technology innovation in a more prominent position, adhere to the strategic basis of independent innovation, and firmly grasp the lifeline of our military development in our own hands. The military field is the most competitive and confrontational, with the most innovative vitality and spirit. Innovation capability is the core competitiveness of an army and an accelerator for generating and improving combat effectiveness. The military competition is ultimately a competition between the innovative capabilities of both sides in combat, and the difference in combat capabilities is essentially the difference in innovation capabilities. Winning the initiative in military competition requires innovation, and the fundamental solution lies in innovation. Whoever holds onto the "bull's nose" of technological innovation and takes the first step in technological innovation can seize the opportunity and gain an advantage. Since the 18th National Congress of the Communist Party of China, the strategy of building a strong military through science and technology has been deeply implemented, with frequent reports of great powers' heavy weapons. The first domestically produced aircraft carrier has been handed over and listed, the third aircraft carrier has been named after launch, the J-20 has been patrolled in the East China Sea, and the Y-20 has been remotely launched. Various unmanned combat systems have developed rapidly... Technological innovation has played a strategic supporting role in the construction of our military, and the construction of an innovative people's army has been solidly promoted. Significant progress has been made in national defense technology and weapon equipment construction. The key core technology is a national treasure, which cannot be obtained, purchased, or obtained. It is not reliable to rely on imported weapons and equipment, and the path of introducing and imitating is not far away. National defense technology innovation has a strong adversarial nature, and relying on others and relying on others is bound to be constrained by others. For a large country like us and such an army, there is no other way out, only to firmly pursue the path of independent innovation. If you are satisfied with 'someone else has something ready to use' and do not master the core technology, you will one day be 'stuck'. At present, the world's unprecedented great changes are accelerating their evolution, and a new round of technological and military revolutions is rapidly developing. Our military construction is in a critical period of achieving the goal of building a military for a hundred years. Technology has never had such a profound impact on national security and military strategy as it does today, nor has it had such a profound impact on the development of our military. We need to make up our minds, seize every moment, organize advantageous forces to fight tough battles, and quickly reverse the passive situation where key core technologies are constrained by others. Especially in the face of some countries implementing "decoupling and chain breaking" behavior, we need to accelerate the capture of "bottleneck" technology and strive to achieve high-level technological self-reliance and self-improvement. We need to handle the relationship between original innovation, integrated innovation, introduction, digestion, absorption, and re innovation, pay more attention to original innovation, and firmly grasp the initiative and development leadership of innovation. Of course, we emphasize independent innovation and never "fight alone" behind closed doors. As President Xi Jinping emphasized, "Independent innovation is innovation in an open environment, and it cannot be done behind closed doors. Instead, it is necessary to gather the energy of the world and leverage the efforts of all parties." Military science and technology workers should firmly establish the ambition and confidence to be the first in the world, correctly handle the relationship between independent innovation and open communication, and change the traditional and closed mindedness
