Anytime I hear about "Chinese engineering" I think of this stupid Chinese dirt bike I used to have which was supposedly a combination of reverse-engineered stuff from Honda and Kawasaki. Stuff fell off with every ride and replacement parts didn't exist. I patched things together with bailing wire and duct tape, literally. Eventually it quit running altogether because the carb was clogged. The best part was that it had an air filter. The air filter was not in any way capable of actually filtering the air that traveled through the air intake, but it technically had an air filter. Sort of like snapping a hitch ball into the seat belt buckle and claiming it's "tow-ready".
I'd hate to see a Chinese jet.
