But Mr. Qian Mu has these four sentences at the beginning of the Outline of National History, which I think is well written. Even though we know that history books only show some of them, we should give them enough respect.
The following is Qian Lao's opening suggestion:
First, when you believe that nationals of any country, especially those who claim that their knowledge level is above the level, should know something about their past history. (Otherwise, he is only a knowledgeable person at most, not a knowledgeable citizen. )
Second, people who know a little about their past history are bound to be accompanied by a kind of warmth and respect for their past history. Otherwise, you only know some foreign history, and you can't have your own knowledge of history. )
Third, the so-called people who have a kind of warmth and respect for their country's past history will at least not hold an extreme nihilism about their country's past history (that is, they think their country's past history is worthless and nowhere to be satisfied). At least we won't feel that we are at the highest point in the past history. This is a shallow and arrogant view of evolution. ) and when all our sins and weaknesses are blamed on the ancients. This is a specious cultural self-condemnation. )
Fourth, when it is believed that every country must wait for its citizens to meet the above conditions, there will be more and more people, and its country will have the hope of further development. (Otherwise, promotion is equal to the promotion of the conquered country or sub-colony, which has nothing to do with the country. In other words, this improvement is tantamount to a disguised cultural conquest, which is only the atrophy and extinction of its culture itself, not its transformation and prosperity. )
