i m from China too, so glad to see a Chinese developer, may i have more detailed suggestion delivered to you？ thanks a lot！

Thanks for the app! It is much better as the new redesigned EPUBreader. Especially I liked the option to import my own style CSS. We can write our favourite font-family, size, colour, background colour, paragraph margin, very good.

Thank you for great app.

I think it's better than EPUBReader! Much more exquisite! Many thanks to the developer!
