All the things that happened in the past, whether right or wrong, have become history, and cannot be changed, nor can they be changed. All people who lived in the past, no matter whether they are wise or foolish, have become dead, and they do not need to be wiped out, and they cannot be wiped out. History It is just a record left in the past, whether future generations like it or not, it will exist. Just like the fossils of the Cretaceous period, after hundreds of thousands of years of time changes, they are still alive. Those who have been enslaved and fought have no faith.
