It's simple. Just enter the National Library of China and connect to the local area network. You don't need to enter a username and password. Just search for the book you want, and you can read it in full. (Note: If you enter the user name and password, you can't read the full text, and you can only read the first 24 pages (it seems to be 24 pages, but you can read the full text in short). If you don't enter a user name and password, you can read the text directly. If you access the network from the outside, you need to pay for reading normally (hourly fee).
