First, you can think about whether there are 56 nationalities and 56 flowers in a song we have heard before, but the correct lyrics are 56 constellations and 56 flowers. Many people have given real evidence. After seeing this evidence, people suddenly felt that they had been punched in the brain. Why? In fact, not everyone's memory has been tampered with, but our ability to process information is not very strong, which leads to some information confusion.
Second, for example, the character Zhang Xueliang and Jay Chou are not of the same era at all, but Zhang Xueliang once heard Jay Chou's songs. This is not time travel, but Zhang Xueliang did live to this time, and everyone won't be deeply involved in getting some information in the community, which leads us to take it for granted. Of course, although the scientific explanation is that this is an illusion, many people say that human life jumped from the original parallel universe to the present parallel universe through time and space, so they think that the space leap has been realized, and this conclusion is indeed feasible in theory.
Third, for example, there are fifty-six nationalities and fifty-six flowers mentioned above. We think so because there are fifty-six nationalities in our Chinese nation, and what we usually hear is only twelve constellations. These 56 constellations are obviously incorrect, but they are correct lyrics, so it is not that the memory has been tampered with, but that everyone's information is wrong.
