Right, those are Taiwanese yellow axis. Right away you can see it is not MX as the stem has a square and MX is rectangle. They have a mostly stolen design of MX switch, fairly similar to blacks but a bit lighter.
I have had a few Dah Yang aka Unitek boards. I thought they were of a good build quality but mine had actual MX switch. Depending on the model, some of them are worth cleaning up. If they happen to have Taiwanese switch they are pin compatible with MX on the PCB, so you could always swap them out. Would be a good starter project to step into modding.
