Look, that's the point! I want to see that there are only two kinds of students here: those who copy the code and those who copy the code.

However, when copying away, you need to think about one thing. After copying away the code, you have an egg to use. It is the most important thing for you to understand.

OK, it's soy sauce.

Old fellow, if this is not acceptable, I can not tell you!!! Oh, by the way, you look so good, pay attention to it...

Finally, I said to myself:
Every misfortune you encounter now comes from a time when you refused to work hard.
