Knock yerself out. Admittedly, some of them don’t affect us very much, and a few of the claims may be in dispute, or were invented independently, in other times and parts of the world. But paper, printing, gunpowder, and the compass were essential to the development of the modern world.
The pertinent question would be what have they invented lately? Not much that we know of, other than perhaps, clever and economical adaptations of various Western and Russian technologies, most of them for warfare. But there’s no monopoly of brains and ambition anywhere in the world, and invention flourishes only where it pays off to the inventor.
Chinese rammed earth walls are impressive. I lived in Weaverville, California for a while. There was a building the Chinese miners had built there, in the 1870’s (Chinese outnumbered whites 2:1 there, for a decade or so.) The walls were about 14 ft high, 60 ft long, and 2.5 ft thick at the base, tapering to 2 ft at the top. They were of the local mud, stomped between rough-cut board forms that were raised, as the wall hardened, and reinforced with 2 inch-3 inch diameter oak branches.
A fire started (jackleg wiring) in one section of the building, destroying the contents of three businesses, and all the wooden roof and partitions. The wall still stood, largely unaffected. By local recollection, that same wall had previously withstood two previous fires, only to serve as the basis for rebuilding — over and over.
After the fire, some people wanted to save the wall as a historical artifact, but the bank that had purchased the property sent a crew in to demolish it (on a Sunday, to avoid confrontation.) The wall was successfully tipped over sideways, but lay on the ground as a single outsized brick. It took a crew with jackhammers a couple of days to break it into truckable pieces.
