Obey the rules. How to post the articles published on the topic refers to the topic of the paper, which should comply with the relevant provisions of the topic paper. Papers that are closely related to the topic are not necessarily the result of the topic. If the paper is used for the conclusion of the topic, it must be highly related to the content of the topic. Once it is relevant but not big, it will not be recognized by the project organizer. Therefore, if the paper is hung on a topic, it is necessary to find a topic that can be hung. Especially when hanging other people's topics, we should understand the disadvantages of hanging other people's topics in papers.
