China's high-tech industry is indeed not as original as Europe and the United States, and many things are made by Europeans and Americans. However, you have only laid the foundation for many things. As long as you do not block the technology, we Chinese can learn and upgrade and optimize on these foundations to make products with better user experience. We have not forced you to give us the technology. It is all based on mutual benefit. We learn on our own. Isn't that a skill?
