Material engineering is the well known blocker for China, same with semiconductors. They basically have to replicate 50 years of trial and error that is well kept under lock in key in the west.
China hasn’t mastered chips either yet in the same way it hasn’t mastered jet turbines: they can do cheap (high yields, low maintenance costs per hour of use), they can do high performance, they can’t do both yet at the same time.

Bollocks. Russia does that as well, single crystal turbine blades in particular so the west is not the sole gatekeeper here. Given the circumstances Russia might as well share the tech for some things in return
I doubt that very much. 20ish years ago I read about the Indians being very upset that the engines in the Sukhoi fighters they bought weren't even making it to the promised (very modest) 300 operating hours between overhauls. That's far less than Western engines routinely achieve. And with the hollowing out of the Russian industrial base that's occurred since then, I'd be surprised if it's gotten any better in the intervening years.
It turns out that they’ve really been able to keep the material sciences data under wraps. It is also really hard to reverse engineer from end products. Same with the C919.

You’re joking. These have been put on network drives since early 2000s and CCP has hacked and exfil them
you don't exactly need to hack a network drive when you can just hire the guy who came up with it
It's not clear to me whether you already knew that those three names in particular are idiomatic in China as the names of 'random' people. 张三，李四，王五.
(Traditionally 李 was the most common surname in China. Last I heard it had been overtaken by 王.)
I don't know who random guys One and Two are.
