How to be a photographer in the entertainment circle

You can go to some small cultural, performing arts and media companies and take pictures of those small artists. The company is promoting your works as well as the artists. If you do a good job and your work is creative for a long time, you will become famous, so that you can enter a bigger company. As for entering these companies, you can look at this kind of recruitment online. Even if you don't want a photographer, you can do something else first, because after all, you said you didn't know anyone to introduce you, so you can only try. This is my suggestion, I hope it will help you.
