Tons of stuff is being rediscovered these days thanks to LiDAR. If you can get past some of the gimmicky stuff (and have Disney+) There's a National Geographic documentary called Ancient China From Above that gets into this in the third episode. A neat thing I learned watching this is that the Chinese flood myth may have some evidence to back it up in the form of an earthquake dam in the Jishi Gorge dated to 1920 BCE that would have flooded the yellow river valley.
