(2) Pay attention to the authenticity of periodicals. You can go to the periodical query page of the General Administration of Press and Publication to check whether the periodical is included.
(3) Just contribute directly to the publication you want to publish, preferably through HowNet. Baidu official website is fake, all of which are impersonated by the intermediary. If you want to contribute slowly, you can find an organization like Tao Tao Paper Network to publish it. This one is quite reliable, others are not recommended.
