It is very useful to study in the education of nitrogen introduction. At the beginning, the teacher taught me a lot of golden sentences and vivid and unique words during the interview at their home. Later, when I took the exam, I said a few words according to them, which was just the finishing touch. I remember that the examiner nodded several times in a row, and as a result, I got a high score in the interview and landed smoothly. Another thing I want to say is that besides golden sentences, nervousness is also a very important factor in the interview.
