I opened the epub file on my DR1000 (with the new firmware), to get the latest Adobe SDK, version 9.1.0.
It looks like the book uses a fixed width and height for the amount of text on 1 page. Small font fills only 1/4 of the screen, while in X-large font I think some symbols even fall off the screen... Seems like the document is formatted and optimized for a certain device.
Perhaps you could use Calibre to edit these settings.
Anyway... I can't be sure because I don't read Chinese... I'll have to check with one of my Chinese collegues...
