"a veteran of China's second ever crewed mission"
Excuse me, but a veteran is someone who is supposed to have significant experience in a particular domain or activity. Doing something once does not give you significant experience.
Fei Junlong was part of the second Chinese crewed mission, no problem there, but that does not make him a veteran.
If he is part of the next three crewed missions after this one, then he will have five missions under his belt and, like a WWII ace, will then likely deserve the term veteran.
But not before.
