1. Don't be greedy for petty gain, there will be no pie in the sky. Good things for no reason (for example, your friend told you that there is a business that can make a fortune, for example, netizens claimed that they fell in love with you at first sight and wanted you to meet her, such as offering part-time jobs to make money), you should seriously consider it.

2. When you are away from home, you should keep in touch with your classmates or parents under any circumstances, and never give your ID card and mobile phone to others.

If it is violated, you should do everything possible to call the police.

4. Do not accept alcohol and tobacco banquets from strangers, do not take illegally operated black cars, and do not enter small hotels.

If you can't get rid of being watched, you can go to a large supermarket and come out without paying. Large supermarkets will call the police and will be detained if they don't pay. You must insist that only the police can search you.

I hope I can help you.
