First of all, we all know? There is a picture and the truth? Now even the pictures are not necessarily true, because of the development of computer technology, it is possible to synthesize pictures artificially, not to mention that there was no camera at that time in ancient times, and people could only record them accordingly. But people's records are written by people, and there must be personal subjective factors, so there is no guarantee that things will be the same as the original records. It is very likely that many times the author added his own subjective views to change the original facts, which we also found in later investigations.
Like the Southern and Northern Dynasties? Describe the difference? There is a record about time travel. At that time, a woodcutter went up the mountain to cut wood. When he came back, he saw two old people playing chess and went to see it. As a result, it was already dark after the old man played chess, only to find that his axe was broken. When he got home, he found that everything had changed dramatically, just like time travel, but we wondered if it was true. Can anyone testify? Not at all, so Bian Xiao still thinks it is unreliable.
There is also Peach Blossom Garden, which we learned in junior high school. There is also the idea of crossing, but there is also a saying that the Peach Blossom Garden is fake, and there is a lot of evidence. Although there is no guarantee that it is, it is enough to see that there is no direct evidence about time travel records in these ancient books, only that there are records in ancient books, but who can testify whether it is true or not? We all know in folklore that one word carries ten words.
