Don’t be stupid and show your heart to everyone.

Don’t be stupid and show your heart to everyone. This sentence is true. People's hearts are often sinister. Some people are the kind of people who talk the talk but do the same thing behind the scenes. They even count the money for the person after he is sold. As the saying goes, you must not have the intention to harm others, but you must also have the intention to guard against others. There is a certain truth to this. Of course, it’s not that there are no kind people, you just have to identify them carefully.
