No need to accuse anyone is pity - you miss my point: I didn't say WS-10 does NOT exist, just about a valid point to fully prove it enter mass service.
Those links you pasted just show there are WS-10, not about mass service is on board.
There is NO theory here, but just a suggestion for solid proof that can help settle the argument. You can challenge my point (why must be maintenance log to show mass service), no need for else.
Greetings, my friend. First, allow me to apologise if you were treated with unfriendly approach, as you can imagine, sometimes, some members do get rather emotional on these topics. As for the so call solid proof, I'm afraid to say it's unrealistic to ask for any engineers, technician to speak of active military hardware in official account except of propaganda agenda, nor there is a chance of documents being released in any circumstance. In fact, it is ridiculous for a military force to release any documents related to their daily operation. If any military do, it's either because they are not serious of their matters, or it's done in a purpose of propaganda, in this case, also "not reliable".
Even if someone provide "documents" as you put it, one can always question the credibility of these documents for obvious reasons. How can I know what these bunches of Chinese characters actually mean? How can I be sure these documents are not fraudulent? Even if they were real, how do I know this is not one of those disinformation campaigns by the Chinese government?
After all, it's just a matter of credibility. One does not believe in Chinese propaganda has no reason to believe words from Chinese citizen or publication, because they have no mean of access to Chinese military information. And if they have, there is a possibility that they are fed with disinformation. So, I think there is no need to struggle oneself with proofing anything regarding this topic
