Question 9: Are all the journals that can be found in Wanfang Database regular? Basically, but there are exceptions. Some journals will also be published in Wanfang, but they are not formal. For example, the name of the publishing department is A, and there is another name B in the middle and late period. Do you think this kind of thing is regular? What's more, A may not be a periodical at all, but a newspaper. Great, B also has to be a newspaper, although it looks more like a book. ,,,, alas, so tangled. I have never done any of these things.
