-There are some people. Don't be ashamed of ignorance of history, but worry about the ancients and tease others. For a person who is not interested in the history of his country, it is hard to imagine what he thinks about the future of this country. People who don't like watching history often repeat the mistakes of historical failure because they don't know that they have learned from the past. Including some historical knowledge that * * * may not know, just look at some bad habits that have been followed for thousands of years, such as welcoming, public money consumption, official standard consciousness and so on. If you don't understand history, it is difficult to have a deep understanding of the cause and effect of things, such as territorial issues and neighboring relations. Without their own historical knowledge, they often have a little knowledge and blindly follow the trend. Such knowledge will only lead to extremism, or be too "patriotic" or indifferent. There is also a first-class fence-sitter, who talks about the east and the west and is ignorant.
