Every history book, whether it is official history or unofficial history, will be influenced by the author's subjective wishes and opinions, and will be influenced by the times at that time, so it is impossible for history books to be absolutely objective and fair.
But when you read a lot of history books and gain more historical knowledge, you will naturally form your own view of history. Festivals will affect your outlook on life, values, success and so on, as well as the way you do things, the logic of judging problems and so on. This is the ultimate goal of our study of history.
It doesn't matter that you study history not to drill in that pile of old paper, not to study whether sourdrang dowager married Dourgen, not to restore historical figures, not to study whether Ji Xiaolan is fat.
The most important thing is to make the past serve the present. It is enough to let the history discipline and knowledge of history really bring some enlightenment to our present life.
