This version is a VIP update free version. You can log in to your Baidu account. After logging in, you can enable the bookshelf function. I have used it for almost a year. My reading experience is excellent. All the books in it can be read for free, which is equivalent to taking a library with me. I have learned a lot of professional knowledge and benefited a lot from this library, So I want to share this software with friends who have learning needs and love reading, and hope that friends can benefit from this software.
