In the case of foreign companies that have technically blocked China, they will not transfer technology with Chinese companies. Even if they transfer, they will not sell the best technology to us. They even transferred the technology and production lines they eliminated. To boost our national industry can only rely on ourselves. After 40 years of reform and opening up, coupled with the unremitting efforts of domestic engineers and technicians for nearly 30 years, it has completely broken through the technical barriers of foreign companies and formed a patented technology with independent intellectual property rights. Now it is no longer necessary to imitate and copy foreign companies. The technology and equipment are now self-contained and in some respects have surpassed their strength. Two bombs and one star, aerospace technology, high-speed rail and other aspects have fully proved the diligence and wisdom of the Chinese. As long as we persist, work hard, correct our attitude, and learn the rigorous and meticulous spirit of the Germans, we have no reason or excuses to chase or surpass them!
