I have encountered this problem many times. I am a graduate student. And as a graduate student in Britain, I also encountered many problems in the process of translating Chinese into English. If it is only translation, it is plagiarism in the strict sense. However, due to the poor translation level. Or language differences. Even professional evaluation software is difficult to compare the similarity. So, if you don't strictly check the source of your article, or you are too harsh. Generally speaking, it will not be found. But personally, from an academic point of view, undergraduates should also study hard. Then write a paper based on your own experience.
