In fact, the submission process of domestic conferences and international conferences is similar. Basically nothing more than this:

Paper writing-finding a meeting-downloading the template of the meeting paper-adjusting the format-submitting-hiring-registering the meeting-meeting-publishing the paper -EI retrieval (if the meeting has been declared). Of course, whether to attend the meeting is voluntary, and generally not attending the meeting will not affect the publication and retrieval of the paper. If you think this process is abstract, you can search Baidu: EI Academic Conference Center, which has a detailed explanation of the process, and each step is explained separately.
