Log in to Bailian Cloud Library, set search items, or click Advanced Search to restrict the search results more. Get the result. Select the point I need to enter. Choosing the way to obtain literature will remind you that you can download it from the corresponding database for the existing literature in our library. For the documents that our library doesn't have, you can choose "Mail Receiving Documents" under "Library Document Delivery", enter your email address in the pop-up window and wait for the documents to be delivered to your email address.
