In fact, whether we can detect what the language is limited to depends on comparing the database. When you submit your paper, the system will compare the data and then generate a duplicate report. Although the paper report is in Chinese, the repeated parts will float in red to show the source of the article.
Most paper-based duplicate checking systems can check small languages, such as paperfree, but each duplicate checking platform contains different data, and the time to update the data is different, and the results are a little different. The first draft can be compared and revised on multiple platforms, and then submitted to the school after being checked by the internal duplicate checking system.
