Explain how you're telling the "truth" on Chinese military aviation? Have any of your prophecies come true? Your comparison to deception vis-a-vis Art of War is also inaccurate; the PLA has already been very open about the jets capabilities and even showed a LRIP in zhuhai. Hence, the PLAAF is not the secretive monolith u claim like the ussr.
Vast amount of scientific research papers exist on the internet, including the Chinese language ones that are published only in China journals, but not in English international journals.
Those papers are not accessible to foreigners, because the language barrier. This included military related papers and aeronautical and aerospace papers. And they are especially not accessible to foreign journalists, and even foreign intelligence analysts, because of their highly technical nature, and the the language barrier. You need to know the Chinese technical terms to search, and the Chinese language ability and technical ability to read and understand them.
Our Mr. Deino, despite being a diligent researcher, is lacking in both.
The Chinese aviation research is quite open, but once classified, they are strictly off limit, just like any other state or military secrets. Chinese Internet censors are rigorous active. Any reports or leaks that they don't like are quickly deleted and the individual or website is severely punished.
Now, they have even learned the technique of spreading disinformations, so that the real and false informations are so conflicting, foreign intelligence agencies couldn't trust the real one they get from human intelligence, because they couldn't tell the real one from the false.
China has not been very open about its military. They only tell, what they want the world to know. China is still very secretive, but not like the former USSR, because of the Internet.
Instead of clam down on the Internet, or cut off connection from outside, China has cleverly used the Internet to its advantages, by building a National Chinese Internet Firewall at the early days of the Internet. It could monitor and block any outside websites, it didn't like. For example, Facebook, Google, Youtube . . . No other country has done that (probably except N. Korea). It is reported that even the use of VPN is now blocked.
I actually spent a lot of time reading aviation papers in Chinese language, and I known that the state of chinese aeronautical has advanced rapidly, because of ample scientific funding, and the huge number of new engineers and scientists that entered the fields, each year.
This is why I am confident that J-20 has been using a
prototype of WS-15 from day one, has
3D TVC, and has at least
210kN of trust. And it is now using a production version of WS-15 on the LRIP J-20.
I am not confident that China has solved the mass production issues regarding WS-15, yet, because I know the long verification process, that could be completed only, after hundreds were built, and tens of thousands of flying hours were accumulated.
This has not happen yet.
Also from reading the Chinese technical papers, I know China is working on an engine, with a very high Thrust to Weight Ratio of 15-20, (WS-10 is 8, and WS-15 is 10-12), and various of other very high tech, state of the art, aeronautical projects.
Again, foreign journalists don't know them, unless they were first reported by Chinese journalists, which are generally not very technical in their reports. This usually happens only, because they have achieve some initial success, so they could celebrate.
"
the PLA has already been very open about the jets capabilities and even showed a LRIP in zhuhai. "
This is quite true regarding J-20, compared to J-10, which not even a picture were leaked, until 2 regiments were in service.
Why such openness regarding J-20? I can only guess. One reason that recently came to my mind is that, openness about J-20 could be a diversionary tactic.
Design to divert attention away from another even more important H-20 project, the strategic stealth bomber.
Several engines with the core of WS-15, will be built, including one, with a large turbofan, that will be installed on H-20. This is why extreme secrecy on the performance and state of development of WS-15. I think.
China's Rocket force will deliver the initial blows. J-20 will be aerial assassins to clear the enemy AWACs and Oil tankers and Fighters. H-20 will deliver the knock out punch, to the enemy airports, ports and other military infrastructures. J-20 will be its long range, stealthy body guards.
or perhaps wait until the MIC-related think tanks in the USA tell us so... 
The J-20 is a heavy air-superiority platform designed for WVR and BVR combat; not interception or strikes. You would glean quite a bit of info if you looked on SDF or read Deino's articles.
