Seeing that you are not in the National Library, if you can generally read it, you can't read it after 24 pages. If you are in the National Library, you can read the full text and just use the local area network of the library (there is no need to log on to the website if there is a local area network).
If you are not in the library, you have to pay to read the contents at the back of page 24, which seems to be calculated by the hour, one hour in 2 yuan.
That's it.
