Can articles published in newspapers still be published on online media and social media?

I have published an article in a weekly magazine under the People's Daily. Due to space restrictions, a lot of content has been deleted. I hope that the original manuscript can also be seen by people. If I publish the original text before the reduction on some online media and self-media, will there be any problems?
The official People's Daily Online version of my article has a statement under every page: "The copyright of the People's Daily Online is owned by all. It is prohibited to use it without written authorization."
"I don't think an individual can get this written authorization. Only the media that they work with can. I saw someone on the Internet answering similar questions and saying that it was okay as long as the source was indicated. However, I was still not at ease because they were well-known journals after all. I still wanted to submit to them in the future and did not dare to offend them.

Answer 1

Generally speaking, articles published in newspapers were protected by law, which meant that articles published on online media and self-media platforms needed to meet corresponding legal requirements, such as obtaining the authorization of the newspaper or following the relevant provisions of copyright law.

However, there were some exceptions. For example, if the article was published in an illegal publication or on an illegal website, the article might not be published in legal media. In addition, if the article is outdated or has been widely circulated, it may no longer be copyrighted in legal media.

Therefore, before publishing an article, it was recommended to confirm whether the published work was legal or not to avoid unnecessary trouble.
