1. Take history as a mirror and guide the future; 2. Enhance national self-esteem and self-confidence; From the perspective of the beneficiaries of history, it can be divided into micro and macro levels, one is the role of history on individuals and enterprises, and the other is the role of history on the country. Let's learn from history and guide the future. From the most utilitarian point of view, MBA teaching should be well deserved. MBA students study to earn more money in the future, which should be the most pragmatic. So what do they study? Ford, Taylor, Ichiro Honda and Dell, whose family history is far or near, are not classic cases of courses such as marketing and human resource management? It is important for people to learn from daily life, but if someone can preserve, sort out and refine it and then spread the essence to the whole world, the effect will be greatly improved. History is actually the experience and lessons of predecessors. If it is handled well and used by us, no matter individuals, enterprises or countries, it will certainly benefit endlessly. Of course, many friends here mentioned the artificiality of historical research. For this problem, I think from the perspective of personal use history, teachers should consciously cultivate students' independent thinking ability, especially for subjective things, they should pay more attention to the process of analysis rather than the result. For example, Zeng Guofan, you said he was a bad guy, but he said he was a good guy. What's the point? He is not my neighbor, and he will not give me money or shave my head. It doesn't matter whether he is a good person or a bad person. The key is to see where his words and deeds are good and bad. Why say yes, why not? What is worth learning and learning from? Get rid of its dross and take its essence. This is the purpose of our research. Besides, enhance national self-esteem and self-confidence. Personally, we should not simply be proud that we were born in China. Because people are actually equal, China has a splendid history of thousands of years, which was created by our ancestors. It doesn't mean that our generation is from China, so we are superior to others, and it doesn't mean that we are smarter and more capable than others. Learning our history is by no means for us to show off to others. But we also have something to be proud of. We should be proud of our hardworking and intelligent ancestors and have the confidence to create a more brilliant tomorrow for ourselves. Be proud of our country and love it from the bottom of your heart. From the point of view that the country uses history as a tool, it is necessary for the country to instill history into all citizens in order to enhance people's sense of belonging, honor and overall cohesion. Only in this way can the country develop better and faster, which is why many things have no guiding significance for our future life, so we still have to protect and explore them, because these are the historical origins that we share as China people, and they are a solid foundation for maintaining our relationship and enhancing our sense of identity. In addition, from the strategic perspective of the survival and development of the whole country, we study history to understand our neighbors and the world we live in.
