Journals are collected by HowNet, Wanfang, VIP, Long Yuan, SCI, SSCI, EI, ISTP and other databases. Only when a journal is included in these databases will the papers published in the journal be submitted to the corresponding database for reference, which is what we call paper retrieval. Paper retrieval is one of the conditions for evaluating professional titles. The key point is to actually confirm whether the unit recognizes Long Yuan. There are many known hownets in China.
