I think they changed the Chinese site as users were getting firmware from that site before officially released to the English market.
I think this is now the newer Chinese site for firmware, Gotostar, Ioptron Gotonova and Ioptron Cubes:

There are a few pages so look for the appropriate page link at the bottom of the linky page i gave.
Be careful you don't update the wrong firmware because it's hard to read the site....
