Because if the document is in English or other languages, when it is translated into Chinese, there is no similar content in the database of HowNet system to compare. Therefore, if the HowNet system contains the English documents you plagiarized, it will not be able to effectively detect the contents translated into Chinese. But pay attention to whether the plagiarized English documents have been used by others. If someone else has translated this document like you, it will be included in HowNet. Then when you test, it will show that you copied him.
