What will you do if your manager in office always angry to you ?

Tell you boss about him

Is that really the only job opportunity you have? Can't you find a job in a different firm?

I too had such kind of experience,.. there was a one Boss he intentionally bully me for one year but as soon I get the opportunity, I took transfer to other city... It was very toxic, that i can't bear him,as he blame and bully me for no reason. Once he called for the meeting and he was parroting me like anything So, I said excuse me Sir, Politely and Left the meeting.. and did not return to meeting.. Later on my colleagues inform me that he, himself, doubt and asked them "Did he talk nonsense"

Develop a habit of tolerating of it is so regular..some people can never be happy and appreciative

If you haven’t already, I would suggest talking to him and telling him how you feel. If you situation is really bad, then surely it won’t make it worse, and it has a very good chance of making it better.

I think you have to try even harder to give your best so there's no chance for then to blame you. Well there are some kind of bosses, ones of them are leader another ones are bossy

I hope your manager realized his bad attitude.he must be a leader specially in good etiquette

Another idea would be to try being extra nice to him. That might soften him.
