There is nothing on Huitong'sAh, not if Huitong confirmed that Z-20s are equipped with WZ-10s, which he did as early as 2018, as I have previously pointed out.
Do you seriously have trouble grasping the following simple facts from Huitong:
1) In-service Z-20s are currently equipped with domestic WZ-10 turboshafts.
2) A different domestic turboshaft (namely WZ-11) might be equipped in the future.
Just how did you interpret 2) to mean "the engine of the Z-20 is still unclear"?
You don't understand my logic because you don't understand logic, period.
