Users are advised to choose international science editors. The service flow of international scientific editors is that after receiving the European quotation email, users confirm that they agree to accept the quotation, and reply to the quotation email in English, clearly indicating that they accept the quotation. After receiving the email from the user agreeing to accept the quotation, the European side will assign the user's article to the corresponding editor to start work. On the other hand, users will receive a short reply email from Europe informing them that the article has been edited. Generally speaking, it takes 5 working days to edit an English article with less than 5,000 words, and 7 working days for LaTex text. Europe will return the article to the author after editing and quality control.
