Generally speaking, if you copy the defense teacher's words, you can hear them by asking a few questions casually, and then see if they want to arrest you. Remember to be fully prepared before replying, even if you don't do anything or know anything, you should act like you have a plan! Don't be silent when he asks, and don't admit that he copied it! Do your homework. It doesn't matter if you say something unreliable. As long as you dare to say it then, you must be confident. In this case, the teacher won't arrest you. If you know nothing, congratulations. Have you thought about it? So many students are listening! It depends on who can speak at that time, so we must make full preparations and look at the data structure and software engineering. If he asks what you really don't admit that there is something wrong with this work, don't say no, just say that you didn't think clearly at that time. I hope the teacher can put forward suggestions for improvement, improve in future work and life, and so on. This is a cliche, flattery, you know!
