all the china technology, almost 100% BS, steal or buy or rob or reversed engineering or copy cat or imitate or fake, all these what china did. Admit it if got gut, then china can improve, behave like thief & bark like liar, will forever live in dark.
this is how big mouth communist sources of liars create their lies from thin air.
just bark whatever lies using mouth but no truth, fact & real existence, lies what they lies as long as can win by paper, no need support data or truth.
same to all comie dogs here but more brainless morons here dont care truth, they accept lies, has to pay back 1 fine day, deserve it!!!

爱国贼们:大爷我就支持美国🇺🇸了,咋滴!
