Can English papers be written in Chinese?

You can use it, but when it is an example, for example, if you write a paper on translation direction and translate slogans, you can quote it if you want to demonstrate and give examples. Generally speaking, except documents and abstracts, other papers should not appear in Chinese.

General academic papers are not allowed and need to be translated into English. If you quote Chinese books or website articles, you need to translate them into English, unless it is special, such as education, and the structure of writing can appear. To know that this is aimed at foreigners, the first condition is that they can understand. As long as they can understand what you are saying, there is no problem.
