Can't trust anyone these days

I thought at least the wiki maintained by miHoyo would be remotely reliable, but even here there's apparently a lot of misinformation.

For example:

怀炎——「烛渊将军」，仙舟「朱明」云骑军将军

Also:

彦卿——仙舟「罗浮」云骑军校尉

But in Yanqing's personal story, his title is 骁卫.

WTF?

( Holy shit, this got long... )

Edit to add: Also, I would like to point out that it is erroneous to use modern Chinese to interpret some of the descriptions in HSR because so much of the language is pulling on the original Classical Chinese meanings.

In classical Chinese (up to the last dynasty, which ended in 1911), 少年 can refer to people as old as 30-35 years old.

And even if I give you the modern Chinese interpretation, according to modern standards, 少年 refers to anyone between the age of 12-17. So...the point is Jing Yuan of Blade's memory probably looked more like:

...and less like
