List of Chinese inventions
I've removed the 4 great inventions claim, as it's obvious that other than perhaps dockless bikes, and you'd need reliable sources for that, the others weren't invented in China. And please don't add text such as "China has once again demonstrated its ability to change the world." This is an encyclopedia, and promotional language isn't appropriate. Thanks.

That's true that "the four great inventions" are not originate in China, but it is China that used the advanced technology to come up with the new inventions and made them China's calling card. There are many new technologies in these four inventions. For example, high-speed railway involves new material technology, motor technology, bogie processing technology as well as network control technology . Qianhanle talk 19:22, 4 December 2017 (UTC)
