Guo Tu doesn't seem to have opened an e-book on the website.
Supplement:
1. If you want to read a book, you need to apply for a reader's card in Guo Tu with your ID card first. It's free to get a card. After completing this card, you can read in many reading rooms in Guo Tu. Chinese, foreign languages, newspapers, books, magazines, etc. Are acceptable. Reading these books with a card is free.
If you want to borrow books, you need to pay a deposit of 100 yuan. If you have a master's degree or above, you need to pay a deposit of 1000 yuan to handle the book lending function (of course, the scope of books that can be borrowed with a master's degree or above is different from that of ordinary readers. So the deposit is more expensive. )
If you want to cancel this lending function, you can return it all with the deposit slip.
