1. If you don't share your secret with others casually, it's very likely that everyone will know it the next day. Even a good friend should be reserved.

2. Don't associate with people who do extreme things, especially when they are out of control and have a tendency to violence, stay away immediately.

Don't participate in off-campus activities alone, such as club sponsorship. Never go alone.

You'd better not drink, and no matter what you drink, as long as the glass is out of your sight, you'd better not drink any more. Sometimes you even have to stare at what others hand you. In case you get dizzy after drinking, you should find an excuse to leave immediately.

Never borrow money, let alone "campus loan". Be sure to tell your parents that no matter what you do, they won't blame you.

6. Don't disclose your personal information casually. Be sure to carry your ID card with you, and don't take it to strange places. It is essential to guard against people.
