First, don't obliterate the achievements of our predecessors and exaggerate our propaganda. Explain that it deliberately devalues the work of predecessors and raises itself; In other words, it is very ostentatious to use such words as "world first", "China first" and "filling the gap in China".

Second, don't forge or tamper with the original experimental data. After the paper is published, all the data must stand the repetition of future generations. When writing a paper, you must never forge or tamper with the original materials, plagiarize or plagiarize. A set of forged data is bound to be incompatible with other real data. You can't modify the original data at will to explain the problem you want to explain.

Third, don't copy or plagiarize the achievements of others. Many domestic scholars plagiarize some or even all of them, and sometimes directly translate English into Chinese.

Fourth, two or even more votes are different. For multiple submissions, the international practice is never to allow a paper to be submitted to different journals at the same time. Note: it is submitted, not published. In other words, submitting articles to two journals at the same time has already belonged to one manuscript and two contributions.

Then there is multi-input in disguise: the same data, completely changed or combined in different ways, which is self-plagiarism. It is also illegal for some scholars to publish the same article in different languages (Chinese and English) in domestic and foreign journals.
