Many years ago when I booked a Y ticket from SYD to PEK, the E-ticket I received stated 30KG, I have called CX before and the agent said it should be 20KG.
I don't know why this happened, but I think it has been like this for many years.
With my past experiences, I think you are safe as long as your bags do not weight too much over 30KG. AND BELOW 30KG IS DEFINITELY SAFE.
