Whether a periodical is official or not depends on whether there is a serial number. Some journals that are not included in HowNet are also official journals (but there are few now). To query the serial number, you can log in to the "Journal of China General Administration of Press, Publication, Radio, Film and Television" under the General Administration of Press, Publication, Radio, Film and Television, Baidu search query website, and enter the query.

But as for what you said, you can judge that it can't be true without checking it. Pedagogy is a first-class discipline recognized by the State Council. It is impossible to have a publication called Pedagogy, so it can be judged from its name that it is not a regular periodical. However, one of the materials copied by the National People's Congress is classified as educational, but it is reproduced from some articles published in other journals, which should not be what you said.
