I added a bookshelf after reading a novel on my phone. I can't add it after deleting it. How can I add it to the bookshelf?

If you want to add the novel back to your mobile bookshelf, you can try the following methods: 1 Open the novel reading app and find the novel you want to add to the bookshelf again. 2. He clicked on the novel to enter the details page. 3. In the details page, there is a "Favorites" button. 4. In the "Favorites" page that popped up, there was a "Save to bookshelf" button. 5 If the novel has already been added to the bookshelf, it will prompt whether to add the novel to the bookshelf again. He could just choose 'Yes'. If the novel is not added to the bookshelf, you can try to download or update the application again or try to find the novel in other reading applications. If you still can't find the novel, you can try to contact the copyright owner of the novel for help.
