For those who question the number of WS-10 engines installed, I can only say that they have no understanding of a world air power. They think that India is a world air power. However, in fact, the scale of its tactical aircraft is similar to that of regional powers such as Japan, South Korea, Turkey, and Saudi Arabia. It is far from being an air power, and naturally cannot understand the scale and quantity that the Chinese Air Force wants to achieve.
Your entire series of WS Turbo Fans ( TFs) are derived from the AL-31F which you successfully reverse engineered way back in the early 2000s. That one act so pissed off the Russians that till 2016 where the CCP signed a contract for 36 nos Su-35 , the Chinese were on the Russian black list.
Up until then you were busy reverse engineering the CFM-56 high bypass TF which is what powers the core of your WS-10.
"A riddle, wrapped in a mystery, inside an enigma," is how Winston Churchill famously described Russia in 1939. The adage applies well, perhaps better, to Beijing's secretive efforts to develop military engines for its future fleet of advanced fighters. While there can be no dispute that engines...

As far as what the PLAAF wants to achieve it's before everyone's eyes. Reverse engineer the source TF & uprate / downrate the TFs as per your requirement.
What does India think of this ? We've been mfg the AL-31FP for our own Su-30 MKI since nearly 2 decades now such that we've acquired the kind of mastery on it that the Chinese acquired on the AL-31F nearly a decade & half ago.
If we really thought the AL-31F was the way to go we'd have begun our version of the WS series program too which would be developing a number of TFs of different ratings to power our Fighter Aircrafts , Transport Aircraft , Bombers etc .
It's just that we think Russian TFs aren't exactly world class which is the reason we haven't sought a partnership with the Russians for our AMCA Mk-2 project which involves designing & developing a clean sheet 120 KN TF with a western partner country namely UK , France or the US.
On the other hand the Chinese have no choice. It's multiple derivatives of AL-31F for you. If you choose to make a virtue out of a necessity that may be good enough to convince your own gullible citizenry or whoever is willing to buy your arguments.
We know the AL-31F inside out therefore we know exactly where does the PLAAF stand on the matter as does the US , the west & of course Russia.
Now sit down & come up with better excuses.
