Why are there stars in this world?

Because stars can appear frequently in front of the public, they can also increase their popularity. More importantly, a profit is a unique patent for stars. In this era, stars are more regarded as idols by ordinary people, and we yearn for stars. However, in the commercial economy, stars are commodities and tools for making money. Different people have different understandings. Stars exist in our society because they have certain value. Without value, there is no abstract business vocabulary of stars.
