1. The funds that can be used to hang papers are usually scientific research funds provided by government departments, including major projects, key projects, Jieqing projects, Youqing projects, general projects of the National Natural Science Foundation of China, postdoctoral funds, key projects of the Ministry of Education and provincial funds, school funds, and various special talent plan funds. As long as your paper is funded by the fund, no matter how much, as long as your application is successful, you can hang it, which is good for the publication of the paper. It will be more difficult to publish a paper without funds.

2. The paper is funded by the fund, so the research content of the paper should at least be related to the content of the project fund. It is not a serious act to mark the unrelated natural science fund number, or even the natural science fund number of the author (similar to a friendly nominal name).

3. If the paper is supported by multiple funds, it must be indicated on the publication page of the paper. But it also means accepting the evaluation and supervision of the public. If your thesis level can't reach the level of fund support, you will definitely be ridiculed by your peers, so you should pay attention to keeping a low profile when you hang up the fund.

4. Don't hang too many papers and funds. More than three will make people think that you are numbering, so if you don't want to close the paper and the fund, you'd better not hang the fund around.
