China's scientific and technological strength is indeed relatively strong in the world, and it is in the first echelon as a whole. In the decades of struggle and development, China has made great progress in high technology, and has reached the world-class level in some high technologies. Therefore, as a whole, China is now basically in the first echelon in the world in terms of high technology. After decades of hard work and painstaking research and development, China's scientific and technological personnel have so far possessed many advanced high technologies in the world.
China now has a high-speed railway network of more than 30,000 kilometers, which has basically reached all cities. China's high-speed railway can operate at 350 kilometers per hour, and China already has a maglev high-speed railway with a speed of 600 kilometers per hour. In this way, China is also in a relatively advanced state in the global high-speed rail field.
At present, China is also in a relatively advanced state in the field of 5G communication. China owns large communication companies such as Huawei and ZTE, and has a number of R&D patents in the field of 5G, thus ensuring that China is in a relatively leading position in the field of 5G.
