I suggest you make preparations in advance. Re-examination is a proposition of various colleges and universities, and there is no uniform regulation. The main forms of oral investigation include: self-introduction; Draw lots to speak impromptu or answer corresponding questions; Read an English article and then translate or answer related questions; Two or three people discuss and debate the same topic; Ask and answer questions freely (it may be professional or professional-related questions, or it may just be about personal situation). Don't be nervous during the second interview, be confident. Fluent in language. Relax and treat it with a normal heart!
