For those who don't know, Zhaoxin _never_ released any x86 product. Over the last 10? years their only output have been laughable roadmaps listing non existing processors.
I've gotten the sense that they're using them, you just can't buy them on the open market. The Chinese government has a ton of uses for passable x86 chips that they control the masks of and could easily consume the whole production line.
They did sell Lenovo computers with renamed VIA Nano processors few years ago while claiming "Zhaoxin's home-grown x86 CPU is completely designed from the ground up within China."
