Article 33 of the Copyright Law of People's Republic of China (PRC) stipulates: "If a copyright owner submits a manuscript to a newspaper or periodical agency and fails to receive a notice of publication from the newspaper or periodical agency within 15 days from the date of publication of the manuscript, or fails to receive a notice of publication from the periodical agency within 30 days from the date of publication of the manuscript, he may submit the same work to another newspaper or periodical agency. Unless otherwise agreed by both parties. " This means that the author is not allowed to contribute more than one manuscript within the specified date.

Extended information At present, most newspapers, including some websites, stipulate that all contributions are non-refundable, and authors can handle them without notice for more than three months. In this case, the author can't receive the confirmation letter from the editor in time, which is also an important reason for multiple contributions.

The timeliness of academic papers is not very strong. A manuscript can be published in the first half of the year and one in the second half. But for some time-sensitive manuscripts (such as essays and comments), if they are thrown into the sea and there is no news, let alone three months, they will become a thing of the past.

The author's painstaking efforts are also invalid because of "expiration". Therefore, in desperation, most authors are forced to choose more contributions for one manuscript, not to make more contributions deliberately, but to publish their hard-earned manuscripts.
