Henan Museum (digital)

Someone carved this flute from a crane's wing bone somewhere between 7,800 and 9,000 years ago. It still plays a scale.

Centre of Central-Plains civilisation (170,000+ artifacts) with an English site + virtual halls showing Shang/Zhou bronzes in 360°.

Cloud multimedia resources (e.g. the ancient-music hall) exist but foreigners usually don't know to look on the English pages.
