Why do some people always like to show off that they are rich?

There are all kinds of wonders in the world, so people also come in all kinds. You know, the more something is lacking, the more it will show off, because this is the reason why a barking dog will not bite. No matter what other people think, in fact, when it brags about it, it is just to satisfy its vanity, so don't care too much about it. What a person shows off shows what he lacks in his heart. The more a person cares about, the more he or she feels inferior. People tend to think about saving face, and sometimes those who brag a lot may be proof of something lacking in their hearts, which requires careful observation. Wanting to cover up, because you don't want others to know what you lack, so you will cover it up by showing off.
