Due to unavoidable reasons, the foreign ChatPDF can only be accessed with a VPN, and it doesn't support selecting specific content for exploratory learning. LiaoLiaoXue solves this problem perfectly: no VPN required, you can pick specific paragraphs to study, or skip selection and go straight to Q&A. It offers the same core functions as ChatPDF, and is an excellent learning platform for students and researchers.
