Thank you for correcting my typo, I use GPT to translate and proofreading by myself. And the result seems like I do need native speaker to do the proofreading in order to get the best quality of translation.
As for Andrea, at first I do use stuttering text in every sentences. But later I think stuttering text may let reader get annoyed. So in the end I choose to use normal text.
I'll add this issue into the questionnaire then decide what method should I use in the future.
