Why does it always split same book into chapters and sections, of which each section contains only few thousand words, which makes reading extremely difficult. Oftenly I spend 60 seconds to read one section and need another
60 seconds to download next. It's so inefficient!

I guess, to be reasonable, they can put one chapter each page. They won't
sacrifice any advertise space anyway.

and not only sina...others also do this
when u download certain video, it also happens
