Your chosen references will be emailed a form through the MNU application, so you will not need to obtain written documents yourself. 参考文献, you will want to enter the name, occupation and email address of the individuals you are using as references.
Please make sure that the email address you use is correct, and one that your references will check regularly, to ensure they receive the recommendation form in a timely fashion.
Here are some sample occupation titles, “Manager”, “Professor”, or “Supervisor”. An email will go to the people you identify, with log-in information. Each will enter their ratings, and they may also upload a letter of recommendation.
