I spent the first three or four years in the United States studying and the last ten years working. All this is in preparation, in order to do something for the people after returning to China-because I am from China. My family name is Qian, but I don't love money. Personally, I'm just a drop in the ocean. What is truly great is the party, the people and our great country. Do scientists only need data and formulas? People who engage in science also need inspiration. Many of my inspirations are realized from art. I think today's science and technology are not only natural science and engineering technology, but the whole knowledge system for people to understand and transform the objective world, and the highest summary of this system is Marxist philosophy. We can't follow the trend. This is not the spirit of science. The most important thing in scientific spirit is innovation. I am a scientist, not a big official. I don't want the treatment of those officials. It is a big problem that China University always fails to produce outstanding talents. It is often the last key that opens the door of the temple. Don't lose heart. As long as you persevere, there will be results in the end. The correct result comes from a lot of mistakes; Without a lot of mistakes, we will not be able to climb to the top of the final correct result. "Nothing is final! ! ! "(No knowledge is final)" Knowledge is infinite "(endless learning). Learning in colleges and universities is a period of laying a foundation, and the focus should be on learning basic courses well. Never stick to your own opinions in scientific work. If you don't have the courage to admit your mistake, you will suffer a big loss.
