Great article, as the regolith issue is one that is too easily overlooked. One thing, though. The various Yutu rover models that the CNSA has displayed are different in many details from the one that actually landed. One, in particular, are the wheels. Instead of using that spiral spoked design, the Chinese seem to have settled on a simpler fixed spoke design. The treads themselves are mesh. The suspension system is otherwise very similar to the ones found on the American Martian rover designs.
The only reason I noticed this difference is because I am trying to build a small, simple, model of Yutu for comparison to my old Hot Wheels Pathfinder Sojourner model (by the way, it is huge in comparison, just based upon the little data the CNSA has shared). I gathered what must have been dozens of images, for what was supposed to be a fun little project. In this GIF, you can see the wheel design on the actual lander a bit better.
