In fact, at present, most official journals in China can be included in HowNet, because the author content of the journals has reached a certain standard, and HowNet is only presented to the public in another form.
However, some false papers in newspapers and periodicals will not be included by HowNet, so it is necessary for the author to find the published periodicals correctly before HowNet can include the papers.
Moreover, there is a certain time limit for HowNet to collect papers, so if you can't find your own papers on HowNet, it may be because you don't have enough time, not because the published journals are fake.
