The 129 page graduation thesis written by the doctoral supervisor of Zhejiang University has been screened. This tutor is very powerful. We all know that in a study at the undergraduate stage, you have to hand in a senior thesis when you graduate, which is what you have learned in a certain major. So, when you say this paper, you have to defend it, but you are online, and you are a graduate student, a doctoral student and a master. Therefore, it is becoming more and more difficult to gradually define the boundaries layer by layer. Especially if you are a doctor, you must study a fixed zero. Then, in that field, I will always focus on the deeper side, or the better side. In this case, if he writes his graduation thesis, the tutor will like it very much, and it is related to a job that he generally likes to study, because it consumes a lot of words and forms, so it is difficult for him to study. So when I was able to write the graduation thesis of 129, I couldn't help but be really shocked by it, because few unforgettable undergraduates can write so many graduation papers now, and I hope all of you here will study hard, and you must change your specific direction through your own study at any time. No matter from which aspect, we need to learn with an open mind and consult our teachers with an open mind. Only in the process of constant consultation and learning can we get something that we can feel right outside, and we can gain some experience whether we succeed or fail. This is how I feel. It is best to sum up your own experience in the case of failure, so that you can gain more insights and cognition. This is what I summed up.
