This question is too good, but it's hard to say clearly. First, let's talk about the official history. In ancient times, it was recorded by full-time historians and then compiled by special personnel. But it is impossible for historians to track and record every link continuously like the current monitoring system. However, the collating editors do not copy, but delete and expand, which makes the narrative of the matter have certain integrity. This will inevitably lead to inference and even speculation.

Unofficial history, outside the official history, has more room for free play and literary interpretation.
