1. The notice of the inclusion of the core journals of Peking University will be sent directly to the mailbox of the correspondent, because the correspondent is the main contact person of the article and the person responsible for communication.

2. If you are the first author of the paper, but you haven't received the inclusion notification email, it may be because the contact information you provided is not accurate or complete. I suggest you contact our editorial department or publishing house as soon as possible to check whether your contact information is correct and confirm the details of the inclusion notice.
