There is a website, but ordinary people can't access the EI database. If you go in, you will be logged in. You can ask your friends who work in colleges and universities. As long as colleges and universities cooperate with EI, they can access EI database through the school intranet. The specific query method is:

First of all, you have to be able to enter EI-enter the title of your paper (in English)-click Search-if you can find the results (usually only one, because the title of the paper is unique)-prove that you have searched-click on the details-where the login number is the search number. Of course, what I said may be more abstract. I suggest you search Baidu: EI Academic Conference Center, which has a detailed description of EI retrieval entrance.
