This problem is just more responsible than the undergraduate teacher. Let's discuss a topic with you first, and then discuss it next semester. Then I will look for materials according to the topic of the paper. If I need a simulation, I will make a physical demonstration. In the process of doing it, if I feel bad, I will discuss it with my tutor, and then I will revise the topic. My tutor usually asks how the paper is written. So I still have to do it alone
