We all know that Microsoft developed the software in the United States, so when using the software, we only need to pay the fee to the United States. Not only Microsoft windows and Android systems, but also Ios is a product made by American software manufacturers.
In this regard, although we are trying to catch up, we need to admit that there is still a big gap. The United States is still very good in top medical care, especially in medical equipment, and it is in a leading position in the world. Many countries are also exchanging medicines with the United States, but the equipment must be purchased from the United States.
In addition, the United States ranks first in the world in the field of engines, not only for civilian engines, but also for military-related fields. Boeing is the largest airline in the world. In fact, what we know about Boeing is not only the production of aircraft, but also the pronunciation machine and cruise system in aircraft, which are products that other countries cannot independently complete research and development.
Therefore, if we want to beat the United States and become the number one in the world, we need talents to be constantly updated in various fields, so that we can truly be self-sufficient. However, the distance between them is gradually narrowing. In the past ten years, the development of China is obvious to all. I think the United States has realized this, so it began to prepare some economic sanctions against us, but it was too late, and China was no longer the nation that was bullied by others.
